Title:
MOTOR DRIVE CONTROL APPARATUS AND CONTROL METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2016174478
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor drive control apparatus capable of avoiding generation of power swing by performing further optimum spark advance control.SOLUTION: A motor drive control apparatus 1 for a motor 20 includes: a spark advance reference voltage generation unit 6 for generating a spark advance reference voltage Vz; a counter-electromotive voltage comparison unit 5 for generating a phase signal of each phase according to cross-timing between the spark advance reference voltage Vz and counter electromotive voltages V1 to V3 of each phase of the motor 20; and a control unit 4 for detecting a rotational speed of the motor on the basis of a phase signal S2 of each phase, increasing the spark advance reference voltage Vz as the rotational speed changes from a high speed to a low speed, and decreasing the spark advance reference voltage as the rotational speed changes from a low speed to a high speed.SELECTED DRAWING: Figure 1
