We’ve all heard linear motors, like those propelling Maglev trains, described as “unrolled” versions of regular electric motors. The analogy is apt and helps to understand how a linear motor works, ...

Ordinary printers used in daily life can print flat objects designed by computers, and 3D printers work basically the same as ordinary printers, but the printing materials are a little different. The ...

For his entry into the 2019 Hackaday Prize, [Tobius Daichi] is working on adding some motion control capabilities to everyone’s favorite Linux SBC. His 3+Pi board attaches to the Raspberry Pi’s GPIO ...

As the shift to automation continues to gain momentum in the industrial sector, servo motors and stepper motors with electric actuators become ever more important. When selecting a motor for an ...

The world is digital today, and most information is represented in numbers. However, human nature is more “analog” and better represented in the old-fashioned way, using pointer gauges and bar graphs.

Stepper and servo motors have different attributes when considered for motion applications. Torque curves play an important role in selecting the proper size and type of motor for an application.

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 ...

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 ...
