 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.
