Abstract
A motor driver system includes an inverter configured to apply a three-phase voltage to a motor; an inverter driver configured to generate a reference voltage to the inverter to control a motor speed to follow a reference speed; and a motor protector configured to control the inverter driver so that a value of the reference voltage is equal to or lower than a predetermined voltage value.
