<P>PROBLEM TO BE SOLVED: To provide a motor drive control device and an image forming apparatus that reduce rotational variations of one electrical angle period component by suppressing variations in energization switching timing in a more inexpensive structure using a small capacity EEPROM. <P>SOLUTION: The motor drive control device includes: a brushless motor; position detection means for detecting a rotor position of the brushless motor; inverter means for switching energization to stator windings of the brushless motor; control means for outputting a drive signal to drive the brushless motor and driving the inverter means in accordance with a signal of rotor position output from the position detection means; and storage means for storing advance information determined in accordance with characteristic variations of the position detection means measured beforehand. The control means performs control to advance the brushless motor according to the advance information stored in the storage means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
