WARNING:
As a stepper motor, it should connect to a constant current or chopper driver. Connecting the motor directly to a power supply will destroy the motor.
To choose a driver, please make sure the driver output current not higher than motor rated current, and voltage not higher than 36V.
Please take care of wires coils order when you connecting to driver or it will damage your driver.
