Abstract
A motor control apparatus includes: a gate control voltage output unit that outputs a drive signal based on a corrected Hall edge that constitutes each of six Hall stages; a counter value acquisition unit that acquires a counter value which is represented by a time period between two Hall edges from the position detection signal; and a switching control unit that allows a value obtained by multiplying a previous counter value of each of the Hall stages by a preset correction coefficient to be a first delay time of each of current Hall edges and allows the gate control voltage output unit to output the drive signal based on each of the Hall edges obtained by correcting each of the Hall edges corrected by the first delay time by a second delay time that advances a Hall edge corresponding to a predetermined sensor among the plurality of sensors.
