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.

    [b]Top 7 Bitcoin Mixers and Tumblers to use in 2022 and Beyond[/b]
    Best Bitcoin blender 2022, Top 5 Bitcoin mixer, Top 10 Bitcoin mixer, Bitcoin mixer

    Initially, Bitcoin transactions were said to be anonymous and completely private. Bitcoin is considered a payment method that cannot be tracked down. But instead, information about Bitcoin transactions is open to third parties. But what if you want to make a completely anonymous Bitcoin transaction? Well, this is where the concept of Bitcoin mixers comes into place.
    Bitcoin mixers are pretty helpful when you want to protect your privacy and hide where your transactions are going.
    However, this is still a pretty new concept to many. So if you are wondering what it is, here is an explanation:
    What is a Bitcoin Mixer?
    A bitcoin mixer or tumbler is an external service. It is basically an internet platform that offers you the mixing service for your coins.
    The service mixes different streams of cryptocurrency and anonymizes it. As a result, you get to gain complete privacy of your transactions and funds. Because Bitcoin mixers make it hard to trace the transaction.
    Also, in today's time, bitcoin mixer services have become a necessity. Since almost all the crypto exchanges now require your personal documents to prove your identity. As a result, your transactions are accessible.
    Though there are many anonymous crypto exchanges available in the market which don't require you to do a KYC but they have their own set of challenges and risks to use.
    The job of a Bitcoin mixer is to break down your funds into smaller sets and mix them up with other transactions. After this process, the recipient gets the same value in Bitcoin. But instead, they receive a different set of coins.
    As a result, bitcoin tracing becomes more difficult, and the bitcoin mixer breaks the link between those specific coins and an individual.
    Also, when you use Bitcoin Tumblers, you receive new coins which are not really associated with your identity. Hence, you regain your privacy.
    However, bitcoin mixer services attract a small fee. But they are pretty helpful in confusing bitcoin tracking solutions tracking down your transactions.
