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.

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 ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

Allegro MicroSystems has announced a new integrated bipolar stepper motor driver IC with built-in translator for easy operation. Allegro MicroSystems has announced a new integrated bipolar stepper ...

Industrial semiconductor expert STMicroelectronics launched its first two STSPIN9 devices as part its new high-current motor-drive series, specifically designed for high-end industrial applications as ...

The new PJE series of bipolar hybrid stepper motors from Nippon Pulse America Inc. are available in sizes from 20 to 86 mm in diameter (NEMA sizes 8 to 34). The motors provide high torque in each of ...

TRINAMIC extends its portfolio of TMCM embedded motor control modules. Following the success of the TMCM-351 triple axis board, the TMCM-3351 is designed to be as easy to use as its sibling, but with ...

They do this with greater efficiency and less motor heating because motor phase currents are regulated up and down according to need. Performance of the closed-loop steppers are similar to servo ...

Even veteran engineers often suffer from a lot of misconceptions about stepper motors and how to drive them. This article will focus on clearing up just a few of these misunderstandings so that ...

Integrating a controller, amplifier and encoder into a brushless dc servo motor, the SM2315 is competitively priced with many complete stepper motor systems. A motion-control chip handles all ...

There are a lot of fun projects you can do with stepper motors salvaged from old printers or disk drives. However, it isn’t always clear how to connect to some strange motor with no markings or ...
