Abstract

An H-bridge circuit controls a motor and includes a first series circuit of switching elements and a second series circuit of switching elements connected in parallel to the first series circuit. A motor driving control method includes a step of turning each of the switching elements Q2, Q3 off and turning-on or performing PWM control on the switching element Q1 and also turning the switching elements Q4 on; a step of performing PWM control on Q1; a step of turning off Q1; a step of repeating for a predetermined number of times a first kickback suppression period during which Q2 is turned on and Q4 is turned off and a second kickback suppression period during which Q2 is turned off and Q4 is turned on; and a step of turning Q2 on and turning on or performing PWM control on Q3.

Description

technical field

[0001] The present invention relates to a drive control method and a motor drive control device for driving the motor by passing a current through a coil of the motor. Background technique

[0002] The driving control method of a single-phase motor will be described below.

[0003] Figure 10 is a schematic configuration diagram showing a motor drive control device of a comparative example.

[0004] Such as Figure 10 As shown, the motor drive control device 101 of the comparative example controls the drive of the motor 20 which is a single-phase brushless motor. The motor 20 includes, for example, a position detector 30 as a Hall element and a motor coil Lm. This motor drive control device 101 includes a control circuit unit 104 , a pre-drive circuit 103 , and an H-bridge circuit 102 .

[0005] The control circuit unit 104 generates a drive control signal Sd based on the position detection signal Sp (position information) from the position detector 30 and...
