Stepper motors are inexpensive and rugged because they have fewer mechanical parts. They are brushless, easy to position, and are commonly used in automation systems, although they are small low power ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

Any stepper motor can be used as a generator. In contrast to other generators, a stepper motor produces a large induced voltage even at low rotational speeds. The type used here, with a DC resistance ...
