CN105529978A - Motor control device, compressor, air conditioner and program - Google Patents

Abstract

The invention provides a motor control device, a compressor, an air conditioner and a program. In a motor control device applied in an air conditioner and the like, restriction on response frequency of the motor control device can be compensated and noise or vibration of a motor can be reduced. The motor control device is provided with an electric power conversion circuit and a control part. The electric power conversion circuit converts direct-current voltage into alternating-current voltage and drives a motor connected with a load device via the alternating-current voltage. The control part outputs a driving signal used for driving the electric power conversion circuit, presumes a rotation angle position (a shaft error delta theta c) of the motor and changes the duty ratio of the driving signal according to a presumed or preset load changing mode (differential torque presumed value delta tm^) and the rotation angle position (shaft error delta theta c).
