Abstract
Motor control devices and methods are described. According to one embodiment, a motor control device includes a resolver to calculates an angle of rotation of a motor in accordance with voltage sensing values from stator windings and a motor controller to calculate an angle of rotation for control by extrapolating the angle of rotation calculated by the resolver based on a time difference between a control timing and a voltage sensing timing of the resolver and to control the motor by using the angle of rotation for control.
