Abstract

The present invention provides a non-sensor motor control device and a method thereof. The non-sensor motor control device includes a control unit, a plurality of switch units, a comparison unit and a motor. The control unit provides a first control signal. The first control signal includes a first starting time. The plurality of switch units drive the motor at the first starting time, and stop driving at a first ending time. The comparison unit outputs a first conversion time point. The control unit calculates the difference between the first ending time point and the first conversion time point, so as to generate a first interval time. The control unit compares the first interval time with a first threshold value. When the first interval time is not equal to the first threshold value, the control unit increases or decreases a second starting time of a second control signal. The motor is based on the second starting time to drive and complete a rotation cycle, thereby increasing the stability of the motor and reducing the power loss.
