Researchers built and tested a low-cost 3D-printed robotic arm that lifted a 0.8 kg payload successfully in all ten ...

Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and 3D printers, ...

Here is an example of a bipolar stepper motor. (Source: pixabay.com) In this article, we are talking about bipolar stepper motors as they are by far the most likely to be encountered by an engineer ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

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 motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.

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 ...

Precise, repeatable valve control within an aircraft’s environmental control system is critical for regulating cabin temperature. Here’s why engineers typically select stepper motors for the job. An ...

Stepper motors are impressive little engines that may not be getting the credit they deserve, as they are a relatively important part of our electronic lives. Printers and CNC machines are ...

Hybrid Hybrid motors consist of a heavily toothed PM rotor and toothed stators, plus prominent rotor poles like a VR rotor. These motors have very fine step angles: 0.5 to 15 degrees. Hybrid motors ...
