Abstract
A motor control device and a motor control method are provided. The motor control device includes a memory and a controller. During an initialization period, the controller drives a brushless DC 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, and the controller stores starting-angle information corresponding to the starting angle and locked exciting-current information corresponding to the locked exciting current in the memory. After the initialization period ends, during a normal rotation period, the controller maintains the rotor position of the brushless DC motor at the starting angle with the locked exciting current through the drive circuit, until the controller activates the brushless DC motor through the drive circuit.
