Title: Brushless motor drive circuit and brushless motor drive system
Inventor: ASUKAI TADASHI
IPC: H02P6/06
Filed: 2010-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a brushless motor drive circuit capable of driving a brushless motor more suitably while suppressing the variation of the power supply voltage caused by the regeneration when the brushless motor is decelerated.SOLUTION: A brushless motor drive circuit has a first AD converter which converts a voltage value depending upon a power supply voltage supplied from a power supply to drive a three-phase brushless motor, to a digital signal and outputs the digital signal. The brushless motor drive circuit has an energization timing adjustment circuit which outputs an adjustment signal for adjusting a lead angle value or a lag angle value of energization timing of the three-phase brushless motor, in response to the digital signal which is output by the first AD converter. The brushless motor drive circuit has an energization timing setting circuit which sets the energization timing of the three-phase brushless motor. If a regenerated voltage is generated by decelerating the three-phase brushless motor with sine wave signals and the power supply voltage rises, then the energization timing setting circuit sets energization timing changed by the lead angle value or the lag angle value on the basis of the adjustment signal to further decelerate the three-phase brushless motor.
