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 ...

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, ...

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 ...

[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 ...

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 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 ...

A new design technique produces corrosion-proof and waterproof stepper motors, extending motor life in harsh outdoor conditions. Electric motors used outdoors are susceptible to temperature extremes ...

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 ...
