  • Drive Circuit is simplified because the motor is driven with star winding connection
  • High torque is obtained at low speed with a mirco-step driver
  • Ultra-low vibration and low noise achieved with our micro-step driver
  • With these drivers, motor step angle is set by selecting from 1/1, 1/2, 1/4, or 1/8
