The determination of the voltage and current of the step motor drive
The driving voltage and current of the usual step motor are selected according to the actual usage requirements, and in theory the smaller the better. The electric current is low and the inertia of the motor is smaller. The inductance will decrease. The step motor usually works at 5 times the rated voltage. The current is less noise than the rated current.
But for the moment, it's all high-speed stepping motors (improving productivity), usually with high voltage, big current motors and drivers. Because of stepping motor and servo difference except for overload, also does not have 3 times the instantaneous current, in order to make up for this gap, by improving the stepper motor power supply voltage and the running current to improve performance is also a good choice.
It's much better than low-voltage motors, such as 110V and 36V, for both torque and speed performance
