Title:
モータ制御装置
Document Type and Number:
Japanese Patent JP6633399
Kind Code:
B2
Abstract:
In a motor control device, a voltage phase detecting unit sets a voltage phase of applied voltage to be applied to a motor based on a deviation between a target d-axis current set by a target d-axis current setting unit and an actual d-axis current detected by a rotor position detecting unit and an actual rotational speed detected by a rotational speed detecting unit. Here, a correction amount calculating unit determines whether or not a rotor has rotated by one period of mechanical angle based on the rotor position detected by the rotor position detecting unit and calculates an average value of deviations between target d-axis current and actual d-axis current in each period of mechanical angle as a correction amount, and a second addition/subtraction unit corrects a target d-axis current by a correction amount.
