الکتروموتور - موتور الکترونیکی چیست؟

(1 رای)

نحوه کار یک موتور DC بر این اصل که قطب های هم نام آهنربا یکدیگر را دفع و قطب های غیر هم نام یکدیگر را جذب می کنند استوار است. سیم پیچی که از میان آن جریان الکتریکی عبور می کند، یک قطب مغناطیسی به وجود می آورد که مرکز آن با مرکز سیم پیچ یکی است. با قطع و وصل کردن جریان سیم پیچ قطب مغناطیسی آن نیز می تواند قطع و وصل شود و یا با تغییر جهت جریان؛ قطب مغناطیسی می تواند ۱۸۰ درجه تغییر جهت دهد. یک موتور DC ساده به طور معمول دارای یک سری آهن ربا بر روی استاتور و دو یا چند سری سیم پیچ در روی آرمیچر است که این سیم پیچ ها دور یک قطب آهنی و البته با ایزولاسیون پیچیده شده و انتهای آن به کوموتاتور متصل است.

آرمیچر شامل برینگ هایی است که آن را در وسط موتور و مرکز تولید قدرت موتور نگه می دارد. سیم پیچ های آرمیچر به چرخش خود دور آرمیچر ادامه می دهند و هم از سیم های تکی و یا موازی استفاده می کنند و می توانند چندین دور به دور دندانه های انباره بزنند ( Stack Tooth ).

Dc Electric Motor Cycle 2

مقدار جریان عبوری و تعداد دورهای سیم پیچ تعیین کننده ی قدرت میدان مغناطیسی به وجود آمده می باشد. تواتر روشن و خاموش شدن یک سیم پیچ خاص معین کننده این است که یک میدان الکترومغناطیسی موثر به کدام جهت حرکت می کنند. باروشن و خاموش کردن یک سیم پیچ به صورت منظم و پشت سرهم یک میدان دوار ساخته شود. این میدهان مغناطیسی چرخنده بر روی میدان های که در روی استاتور وجود دارد و این میدان ها ممکن است توسط یک آهنربای دائمی و یا سیم پیچ به وجود آید واکنس می دهند و باعث به وجود آمدن نیرویی که آرمیچر را به چرخش در می آورد می شود. موتورهای DC در توان های بالا معمولا توسط تزیق هوا به داخل آنها خنک می شوند.

کوموتاتور به هر یک از سیم پیچ های آرمیچر اجازه می دهد که در نوبت خود فعال شوند. جریانی که سیم پیچ ها را تغذیه میکند به طور معمول توسط دو جاروبک و یا ذغال که با کوموتاتور اتصال لغزشی دارند برقرار می شود.

با پیشرفت تکنولوژی موتورهای DC بدون فرچه و زغال ساخته شده اند که دارای مدارات الکتریکی مرتبط ، جهت روشن و خاموش کردن جریان سیم پیچ آرمیچر هستند. این موتورها فرچه و ذغالی ندارند تا فرسوده شده و یا تولید جرقه کنند. از این الکتروموتورها در مکانهایی که تولید نویز ایجاد مشکلات عدیده ای می کند استفاده می شود ( مانند بیمارستانها و مراکز پردازش داده)

تعداد قطب های استاتور و آرمیچر و چگونگی اتصال سیم پیچ ها به یکدیگر ( سری یا موازی ) فاکتور سرعت / گشتاور این موتور ها را مشخض می کند. سرعت یک موتور DC می تواند با تغییر ولتاژی که به آرمیچر می دهیم تغییر کند. استفاده از مقاومت متغیر در مدار آرمیچر و یا مدار میدان به ما اجازه ی کنترل سرعت را می دهد. موتور های مدرن DC معمولا با مدارات الکترونیکی قدرت کنترل می شوند که این مدارات ولتاژ را با بریدن و تنظیم زمان قطع و وصل تنظیم می کنند که دارای ولتاژ کار پایین تر و موثرتری نیز هستند.

الکتروموتورهای DC سری دارای گشتاور زیاد در سرعت های پایین هستند. از این الکتروموتور ها در کاربردهایی چون لوکوموتیو های برقی و دیزل الکتریکی ، ترامواها و دریل های برقی بزرگ استفاده می شود.

معرفی موتور DC و یک سیستم برق رسانی برای به حرکت درآوردن ماشین آلات باعث به وحود آمدن یک انقلاب صنعتی دیگر در دهه ی ۱۸۷۰ شد. موتورهای DC می توانند به صورت مستقیم به باطری های قابل شارژ کار کنند و این اصل نیروی پیش رانه اولین خودروهای الکتریکی و اتومبیل های مرکب امروزی و حتی دستگاه های بدوم سیم را تامین کرد. امروزه موتورهای DC کوچک هنوز در کاربردهایی چون اسباب بازی ها و پرتاب کننده های دیسک و یا در سایزهای بزرگ برای به کار انداختن غلتک های گردان فلزات در کارخانه های نورد و ماشین های کاغذ بری بزرگ مورد استفاده قرار می گیرند.

اگر توان خارجی به صورت مکانیکی به یک موتور DC داده شود این موتور به عنوان یک ژنراتور DC یا یک دینام کار می کند. از این خصوصیت برای شارژ باتری خودروهای الکتریکی و مرکب (هیبریدی) و قطار های برقی وقتی که اقدام به کاهش سرعت و ترمزگیری می کنند مورد استفاده قرار می گیرد. این پروسه را ترمز احیا کننده می نامند. در لوکوموتیوهای دیزل الکتریک نیز از موتور های DC به عنوان ژنراتور برای ترمزگیری استفاده می کنند که این انرژی در بسته های مقاومتی ( Resistor Stack) تلف می شود. اکنون در طراحی جدید بخشی از این انرژی را در باتری ها ذخیره می کنند.

    Typically users might be having an underlying health situation which
    may worsen with using Sustanon. It is at all
    times essential to get a check-up before you start using any steroid, simply to
    be sure. By utilizing a good PCT (post cycle therapy) complement,
    you'll be able to assist to reduce the chance of many of these
    unwanted effects. Most bodybuilders, health lovers, and athletes who use Sustanon 250
    cycle report experiencing decreased recovery time between exercises.

    When you cycle these substances, you’ll be in a position to improve your general power while additionally decreasing the risk of
    unwanted aspect effects.
    Nonetheless, we now have found this to be one of the higher cycles for avoiding man-boobs.
    With Winstrol being a C17-alpha-alkylated steroid, it'll trigger liver strain while lowering HDL cholesterol and elevating LDL through the stimulation of hepatic lipase.
    All of this, mixed with a scarcity of aromatization, will cause potential damage to
    the center.
    If the cycle is for eight weeks, this acquire can be around 25 to 30 lbs.
    Nevertheless, the longer the run, the extra doubtless it is for
    you to undergo its unwanted effects. So, it's an official
    veterinary drug used mostly for enhancing cattle mass to obtain meals.
    These days, Trenbolone Acetate, one of many Tren types, is used as
    veterinary medication. Nevertheless, scientific research
    are ongoing with Trenbolone for human use.

    The finest method to learn the way your body will react is to begin with a lower dose and enhance it gradually over time.
    This will assist you to to gauge your tolerance for
    the steroid and minimize the dangers of unwanted facet effects.
    Moreover, Trenbolone additionally stimulates the production of purple blood cells, resulting in elevated
    vitality levels, stamina, and recovery time.

    We have discovered that isotretinoin, better often recognized as Accutane, might help bodybuilders that suffer from acne but need to expertise the advantages of trenbolone (or different
    androgenic steroids). It is important to note that particular person responses to Trenbolone can vary,
    and dosages must be adjusted based mostly on private tolerance and objectives.
    It is advisable to start with the lower end of the beneficial dosage vary and progressively improve
    if essential, whereas intently monitoring any potential unwanted effects.

    Blood pressure will need to be monitored very regularly on this cycle, as
    it’s likely to spike to very high ranges.

    Trenbolone Acetate is a potent anabolic androgenic steroid
    (AAS) that belongs to the 19-nor (short for nor-testosterone) household.
    It is derived from the primary male sex hormone,
    testosterone, with structural modifications to reinforce its anabolic properties.

    Trenbolone Acetate is extremely regarded within the health and bodybuilding community for its distinctive ability to advertise muscle development, increase power, and enhance athletic performance.
    Trenbolone stands out as some of the transformative tools available to bodybuilders,
    offering unparalleled advantages in muscle progress, fats loss, and efficiency enhancement.
    Its capability to accelerate protein synthesis, enhance strength, and optimize body composition makes it a robust choice for those aiming to
    achieve peak physical outcomes. Whether for bulking or chopping, Trenbolone’s versatility and effectiveness
    have cemented its place as a go-to option for critical athletes and health fanatics.
    It acts as a stimulant, so potential side effects will have an result on everyone
    in one other way – put together to alter the dose if required and monitor your blood strain throughout the cycle.

    However after a while, the one issues on hearth will be
    these volcanoes on your face and back. Even with a basic, low-dose cycle of Trenbolone,
    your blood stress can spike dramatically. Some severe drug customers
    even stack another drug known as Cardarine with their Trenbolone to assist manage the
    signs.
    Moreover, setting realistic expectations is important, as Trenbolone just isn't a magic
    answer but rather a tool that can improve your efforts.
    By clearly defining your fitness objectives and managing expectations, you could make extra informed decisions about dosage,
    cycle size, and the general strategy to utilizing Trenbolone.
    This steroid escalates nitrogen retention within muscle tissues, fostering an optimal
    state for accelerated muscle development
    and repair. This steroid’s knack for catalyzing protein synthesis is another key contribution, amplifying the muscle-building
    potential harnessed from protein consumption. With an upward
    shift of almost 20% muscle power visible within weeks, users can raise
    heavier weights, promoting muscle hypertrophy.
    By following a Trenbolone cycle and using it responsibly, you may get essentially the most out of this highly effective steroid while minimizing the dangers to
    your health. Trenbolone has a chemical structure that is much like other anabolic
    steroids, however it has a few key variations. It has a double bond on the ninth and
    eleventh carbons, which makes it proof against
    the enzyme aromatase. This implies that Trenbolone won't convert
    to estrogen in the physique, which might trigger unwanted
    unwanted effects like gynecomastia (the growth of breast tissue in men).
    The three steroids you talked about are all very popular choices for these seeking to bulk up
    and achieve lean muscle mass.
    Trenbolone and Deca Durabolin are each injectable bulking steroids, yet they are fully unique of their pharmacology and effects.
    We have discovered Equipoise to be extra estrogenic than Deca Durabolin, with EQ
    displaying 50% much less estrogenic effects of testosterone however 400% greater than Deca
    Durabolin. Research point out that Deca Durabolin is
    mostly well-tolerated by ladies when taken in dosages of a
    hundred mg (6), administered every different week for 12 weeks (thus translating as 50
    mg/week). Although Deca Durabolin will not be essentially the most optimum steroid
    for women (with Anavar being a extra suitable compound), research suggests Deca Durabolin presents a low risk
    of virilization. We find this cycle higher suited to someone nervous about gynecomastia,
    as an aromatase inhibitor (AI) can be taken, synergistically
    lowering estrogen and progesterone ranges. Thus, by stacking Dianabol
    with Deca Durabolin, users is not going to be greatly aggravating these two signs, with Deca being an injectable
    and having less toxic results on blood lipids.


    The principle that anabolic steroids cause "roid rage" is largely a myth;
    quite, AAS use could potentiate "aggressive" qualities in individuals who behave
    that method innately. Trenbolone acetate is a modified form of nandrolone.[16] The structure of trenbolone
    acetate is a 19-nor classification, which represents a structural
    change of the testosterone hormone. Trenbolone acetate lacks a carbon atom on the 19 place and carries a double bond at carbons 9 and eleven. The place of those carbons slows
    its metabolism, which tremendously increases its binding affinity to the
    AR, and inhibits it from undergoing aromatization into the
    corresponding estrogenic metabolite. In the livestock industry, trenbolone acetate is
    more often referred to as Finaplix. It was intentionally developed
    to advertise androgen and achieve muscle mass in cattle.

    Due to its properties, this permits livestock to develop as a lot muscle as attainable earlier than they are transported to a slaughterhouse.


    This might help optimize the benefits of the trenbolone cycle by guaranteeing that you simply're focusing on particular
    muscle groups and incorporating workouts that promote strength and hypertrophy.

    We know we’ve already checked out a trenbolone acetate, but to help refresh your memory and
    to clear up the precise dosages of tren ace you will want 75mg of Tren-ace each other day for the primary four weeks.
    It isn’t unusual for individuals to realize upwards
    of 30 pounds of muscle mass with only one tren-ace cycle.

    It Is important to note that Tren is a potent androgenic steroid and must be used with warning.
    It is often recommended for knowledgeable customers who have a
    strong foundation of training and vitamin. Earlier Than contemplating Tren for fat burning functions, it is crucial to consult with a healthcare skilled or a educated
    professional who can present steerage on dosage,
    cycle length, and potential unwanted effects. However
    the optimistic results of anabolic steroid
    use are irrefutable, and trenbolone (acetate and enanthate) remains one of
    the highly effective performance-enhancing medication for muscle development.

    This Cutting Stack bundle incorporates Anvarol, Clenbutrol, Winsol, and Testo-Max.
    Together, these merchandise promote a lean physique
    and increase fat burning while preserving the muscle mass you've got constructed up.
    Nonetheless, many of these studies use exorbitantly massive
    doses of β-sitosterol, particularly animal studies, which use anywhere between 20 and 100mg/kg.
    Research research on each of Trenorol's 4 components show that they can enhance athletic performance, assist muscle building, or speed up fats burning.

    Tren customers expect large will increase in energy and lean muscle positive aspects
    on cycle. In the world of bodybuilding and athletic performance, the choice between Trenorol and Trenbolone can be
    difficult. Both supplements aim to provide elevated energy, muscle development, and
    fat-burning. Nonetheless, there are significant
    differences between them that want cautious consideration. Testo Max makes use of some potent natural testosterone boosting components toincrease testosterone ranges which is the basis for the method it
    delivers huge gains in muscle, strength and restoration time.

    Trenbolone is a powerful steroid that can ship impressive results, however it
    additionally comes with potential unwanted facet effects.
    By understanding these dangers and following correct guidelines to be used, people can reduce
    the probability of experiencing antagonistic results and achieve their health targets safely.

    However as with every androgenic side effects, each particular person has their
    own expertise. You could be one of many lucky ones who isn’t genetically predisposed and get away with minimal androgenic results.
    When we’re using most other anabolic steroids, there’s a fairly
    good thought of what kind of unwanted facet
    effects you possibly can count on. Most steroids share an analogous aspect impact profile, however Trenbolone is a little
    bit of an outlier. The many variables make it impossible
    to outline ends in black and white. You should consider your dosage and cycle size, another compounds you’ve added to
    the stack, the kind, intensity, and frequency of your workouts,
    diet, and genetics – only for starters.
    In addition, the results showed that trenbolone acetate additionally promoted greater satellite tv for pc
    cell activation and growth in skeletal muscle tissue.
    Trenbolone acetate is considered essentially the
    most anabolic steroids in the marketplace and for good reason. This compound has been shown to be more
    practical than other anabolic steroids by way of muscle development, energy gains, and stamina.
    Trenbolone is essentially a spinoff of Nandrolone
    with some very important variations in its chemical properties and power.
    Trenbolone and its parent hormone Nandrolone each belong to a class/category of anabolic steroids known as 19-nor compounds,
    or 19-nors (short for 19-nortestosterone).
    Anadrol is estrogenic, inflicting vital amounts of water retention and potential gynecomastia in customers.
    Nonetheless, it doesn't aromatize, so taking an aromatase inhibitor (AI) is not going to
    be effective in preventing gynecomastia or water retention from
    Anadrol. To try and hold blood strain as little as possible, customers are really helpful to take 4 grams of fish
    oil per day, combined with clear eating and common cardiovascular exercise.

    Although cardio may be the very last thing a bodybuilder needs to do when bulking, it’ll
    provide cardiac safety. We typically see Anavar shift cholesterol levels, lowering HDL and growing LDL;
    due to this fact, a modest improve in blood stress should be anticipated
    (7). Anavar/testosterone cycles have been shown to
    considerably increase lean mass throughout bulking while simultaneously stopping fats gains.
    A first-time cycle (like this one) can produce roughly 20 pounds of
    lean mass.
    From anabolic steroids to SARMs to peptides and ancillary medicine,
    I've carried out it sooner or later in my life, and I can relate.

    Tren Hex (Trenbolone Hexahydrobenzylcarbonate) is the massive ester type of the anabolic steroid Trenbolone.
    It has a protracted half-life of about 14 days and
    slowly releases Trenbolone into the body after injection. Tren Hex features equally to other Trenbolone steroids, the one distinction being the
    discharge price with the connected hexahydrobenzylcarbonate ester.
    Optimistic Trenbolone reviews give attention to how much muscle has been gained
    and the way quickly (expect it to be quite
    fast), strength gains, and fats loss or body recomposition. Equipoise and Dianabol, working alongside Parabolan and testosterone at
    replacement degree dosage, will present some of the powerful bulking combos potential.
    Dianabol at 25mg daily provides a potent cycle kickstart and is simply used for the primary six weeks as it's a fast-acting oral steroid.

    Trenbolone binds to and activates androgen receptors, which are found in numerous tissues all through the body.
    The idea that anabolic steroids can reduce
    sexual operate is a standard one, and it is true that some steroids can have negative effects on sexual operate.
    We have identified of customers who're relatively new to anabolic
    steroids, including almost a hundred pounds to their
    bench press on trenbolone inside the first month of a
    cycle. Thus, when a person cycles steroids, we see their
    overall testosterone levels shoot up, but their natural testosterone levels plummet as the body detects extreme
    hormone ranges.
    Trenbolone additionally boosts metabolism and
    comes with the good factor about not causing water retention. With Out water retention problems, Tren retains you dry and lean and is an final chopping and conditioning steroid.

    This is crucial not only for health causes but
    in addition to take care of the features you’ve made in the course of the cycle.

    Mechanistically, tren is very similar to different anabolic and androgenic steroids.
    Trenbolone has the capability to produce insulin like progress factors, (IGF-1), as nicely as upregulates fibroblast development factor.

    Particularly, tren is classified as a steroidal selective
    androgen receptor modulator (SARM). The three steroids you mentioned are all very
    popular selections for these trying to bulk up and gain lean muscle mass.

    This isn’t a knock on their providing, though, as very
    few nutritional supplements will ever get approval from an insurance
    company. That guarantee is designed to allow you 60 days to try the product and as a lot as
    every week to return it after that. As lengthy as you come any bottles (used or
    unused) inside sixty seven days, the corporate will refund you 100%
    of your buy price.
