[Tobias Kuhn] had watched a YouTube video about a robot arm which used servo motors, and wanted to try making one himself. But he found it hard to get slow or smooth movements out of the servos. Even ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

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.

The first installment of this two-part series focused on debugging brushed-DC motor systems. Now the second installment will share some tips for stepper motor systems and provide general bench testing ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

Stepper motor drives are devices used to power and control stepper motors. While some basic drive units only supply power, many commercially available drives also incorporate controller electronics ...
