Step Motor Voltage

Q: Can you tell me exactly how much voltage is supplied to the motor from your drivers?

A: If you're using one of Oriental Motor's 24 VDC input drivers (or any DC driver), the power supply voltage is applied to the motor. If you're using one of our 115/230 VAC input drivers, the voltage is rectified to DC and then approximately 140 VDC is applied to the motor. There are exceptions to this rule. Since the motor is receiving more voltage from an AC input driver, the motor will have better torque characteristics in the high speed range. You can tell by looking at / comparing the speed-torque curves that we provide for our motor/driver packages. In some of our torque-speed curves, we do show curves corresponding to different drive voltages.
