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 ...

Stepper motor drive When a two-pole permanent magnet is used in the motor rotor, one full-step corresponds to a mechanical angle of 90 0. Each full step can be further divided into a number of ...

Hybrid stepper motors combine the operating principles of variable reluctance with permanent-magnet stepper motors. The rotor shaft holds one or more pairs of stacked laminations containing many teeth ...

Step motors provide accurate position control without the need for feedback, traditionally in open-loop control schemes. A stepper motor’s shaft normally makes discrete angular movements of ...

Over the last two decades, stepping motors (or step motors) have increasingly been applied in electronic-control applications throughout all segments of the electronics industry. Its simplicity of ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

Stepper motors are well known for their ability to perform accurate positioning in an open-loop mode. But they have a reputation for generating a lot of heat when rotating at high speeds. Generation ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Gree Electric Appliances Inc of Zhuhai has filed a patent for a rotor structure, electric motor, and rotor manufacturing method. The rotor structure includes stacked rotor sheets with a shaft hole, ...
