This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of ...

Uni- And Bipolar Bipolar Stepper Motor Driving Circuit (Credit: Monolithic Power) The difference between unipolar and bipolar design is covered in this stepper motor overview by Monolithic Power.

If you want a simple and easy introduction to stepper motors, check out the [IMSAI Guy]’s short video where he designs a very basic stepper motor controller and packs in a lot of quick lessons ...

Stepper motors generally include a motor, drive, and controller. The motor, a brushless dc version, moves in equally sized fixed steps during rotation, and only rotates one step at time.

For example, the figure shows a USB-based controller for four stepper motors built using inexpensive off-the-shelf components. The circuit requires no microcontroller or DSP.

The CMMS-ST single-axis position controller combined with the EMMS-ST stepper motor is designed as a comprehensive, easy-to-use package for single and multiple-axis handling with loads of up to 20kg.

Two-chip designs combining a microcontroller or DSP with a highly integrated driver IC simplify the design of a stepper-motor controller, while also enabling sophisticated control features that ...

Toshiba Electronics Europe has started sampling a 40V/3.0A stepper-motor control IC that requires no external current-sense resistors, making it possible to develop both more economical and compact ...
