Abstract: The present disclosure relates to a motor rotor control device and method capable of reducing noise caused by the alignment of a motor rotor, and securing stability of staring a motor.
The motor rotor control device in accordance with an embodiment of the present disclosure includes a motor having a rotor; an inverter for supplying a three-phase alternating-current voltage to the motor; and a control unit for estimating the initial location of the rotor upon the initial driving of the motor, correcting the location of the rotor by a predetermined angle from the estimated initial location, and then driving the motor.
