Title:
MOTOR DRIVING SYSTEM AND MOTOR DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/118318
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a motor driving system and a motor driving method capable of improving motor output taking into consideration a voltage waveform of a voltage application unit that drives the motor. The motor driving system is equipped with: a motor; a current detection unit for detecting a motor current of the motor; a magnetic pole position detection unit for detecting a magnetic pole position of the motor; a control unit for generating a voltage command on the basis of the motor current, the magnetic pole position, and an externally supplied operating condition; and a voltage application unit for applying a drive voltage to the motor on the basis of the voltage command. The motor is configured such that a harmonic component is superimposed on the fundamental wave component of an induced voltage of the motor so that the waveform of the motor drive voltage takes the form of a trapezoid wave that is expanded from a sine wave.
