Here is how to implement a stepper motor to sense position and actively correct any error that might accrue during actuation.

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 ...

Unlike brushed varieties, brushless dc motors cannot be operated directly off of straight-line dc voltage. Remember, brushless motors use electronic commutation — so again, no brushes make physical ...

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.

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

New and existing stepper motor applications will benefit from SILENTstep, a sensorless drive and control system developed by Agile Systems and available in the UK from LG Motion. The new modular drive ...

It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

Klaus Neuenhueskes looks at brushless DC motor control in cars and discovers that H-bridge controllers have specific advantages for designers. According to a recent report by research firm IHS, around ...
