  • Patent number: 10447182
    Abstract: The present invention provides a control device and a control method for a brushless motor, including energization modes for selecting a phase to be energized by pulse width modulation operation from among phases of the brushless motor, and being provided for controlling the rotation speed of the brushless motor by switching between the energization modes based on comparison of a voltage induced in a non-energized phase with its threshold value. In the control device and method, the input voltage of the brushless motor is increased when the duration for which the induced voltage is maintained unchanged or the duration for which the current energization mode is maintained employed reaches a predetermined time. This prevents the brushless motor from being staying in the stopped state, even when the load on the brushless motor abruptly increases while the brushless motor rotates at a speed within an extremely low speed range.
