PROBLEM TO BE SOLVED: To provide a motor drive control device capable of controlling a motor without being restricted by a function of a motor drive part, and a motor drive control method.SOLUTION: A motor drive control device 1 comprises: a Hall element 4 having positive and negative polarities; a motor drive part 2 including a start support function for setting a PWM signal to be electrified to a motor 20 at a predetermined duty ratio for a predetermined time after the motor 20 is started; an inverter circuit 5 for inverting output of the Hall element 4; and a control circuit part 3 which controls the inverter circuit 5 and outputs a desired Hall element signal to the motor drive part 2. When starting the motor 20, the control circuit part 3 performs control for cancelling the start support function of the motor drive part 2 by inverting the Hall element signal iteratively predetermined times or more by the inverter circuit 5.SELECTED DRAWING: Figure 1 |
