Abstract:
A fan motor control device that, when in a state in which a control unit (10) cannot obtain a rotation request (LO request) at a first rotation speed and control is being performed on the basis of a rotation request (HI request) at a second rotation speed from an OFF request, changes the lock current threshold from a first threshold value (first level) to a second threshold value (second level), and, after a prescribed time period has passed after a second drive signal is output on the basis of the HI request, returns the second threshold value (second level) to the first threshold value (first level).
