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's output current not higher than motor rated current, and voltage not higher than 36V.
* Please take care of four wires coils order when you connecting to driver, or it will damage your driver.
