Motor control device and motor control method

A motor control device, comprising:

• a memory, adapted to store at least one control parameter, wherein the at least one control parameter comprises starting-angle information and locked exciting-current information;
• and
• a controller, coupled to the memory to access the at least one control parameter, wherein during an initialization period, the controller drives a motor to change a rotor position through a drive circuit for adjusting and obtaining a starting angle and a locked exciting current corresponding to the starting angle, the controller stores the starting-angle information corresponding to the starting angle and the locked exciting-current information corresponding to the locked exciting current in the memory, the starting angle and the locked exciting current corresponding to the starting angle are determined before a normal rotation period starts, and the normal rotation period is performed if the rotor position of the motor is at the starting angle before the normal rotation period starts;
• and
• after the initialization period ends, during the normal rotation period, the controller maintains the rotor position of the motor at the starting angle with the locked exciting current through the drive circuit until the controller activates the motor through the drive circuit.
