Driving a 3-Phase Stepper Motor With a BLDC Motor Driver Reference Design


Design files


TIDA-01362 demonstrates how to drive a three phase stepper motor using the same hardware structure of a Brushless (BLDC) driver. By regulating the PWM signal schemes, the design achieves a smooth sinusoidal output current. DRV8313 device is used for the implementation of this design.

  • Smooth Current
  • Compact design
  • Low noise operation
  • Open Loop operation
  • Very low to no vibrations
