Title:
MOTOR DRIVE DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2015/072048
Kind Code:
A1
Abstract:
A motor drive device comprises: a motor current phase detection unit (102) for detecting a motor current phase and outputting the detection result as motor current phase information; a motor phase detection unit (104) for detecting a motor phase and outputting the detection result as motor phase information; a phase correction value calculation unit (105) for, based on the difference between the motor current phase information and the motor phase information, calculating a correction value and outputting the calculation result as correction information; and a motor-applied voltage calculation unit (106) for receiving the correction information and the motor phase information to calculate a motor-applied voltage indicating a voltage applied to a motor and outputting the calculation result as a motor-applied voltage signal (107), the phase of which is corrected.
