Abstract
The control part includes: a gate control voltage output unit that is configured to output a drive signal which switches a switching element according to a Hall edge that forms each of six Hall stages which are represented by a combination of electric potentials of position detection signals that are outputs of a plurality of sensors; a counter value acquisition unit that is configured to acquire a counter value which is a time period of the Hall stage and which is represented by a time period between two Hall edges that form each of the Hall stages from the position detection signal; and a switching control unit that is configured to determine a value obtained by multiplying a previous counter value of each of the Hall stages by a preset correction coefficient as a delay time of each of current Hall edges and that allows the gate control voltage output unit to output a drive signal according to each of the Hall edges which are corrected by the delay time.
