摘要： A phase-shift detection circuit detects a phase shift in motor driving, using pulse-shaped position detection signal Rd and measurement signal Ms. The position detection signal is based on sensor signal Hs from a position sensor disposed in a motor. The measurement signal is based on the induced voltage from windings. The phase-shift detection circuit includes a level difference calculator and a phase-shift calculator. The level difference calculator calculates a level difference between the level of measurement signal Ms at a rising timing of position detection signal Rd and the level of measurement signal Ms at a falling timing thereof. The phase-shift calculator calculates the amount of phase shifts based on the level difference.

摘要： A motor control device according to the present invention includes a motor driving unit for driving a motor, a current vector controller, a magnetic-flux weakening current command generator, and one of a target command limiter and a q-axis current command limiter. The current vector controller controls a current of the motor by separating the current into a d-axis current and a q-axis current orthogonal to each other, in accordance with a target command value from the outside. The magnetic-flux weakening current command generator generates a d-axis current command to control the amount of the d-axis current, based on one of differences, i.e. a difference between a first predetermined reference value and the absolute value of a voltage command from the current vector controller to the motor driving unit and a difference between a second predetermined reference value and a q-axis component of the voltage command. The target command limiter sets a limit value of the target command value from the outside, based on an excessive amount of the d-axis current command over a negative upper limit.

摘要： In a motor control apparatus for controlling a rotational position of a motor, a rotation detector detects the rotational position of the motor, and outputs first and second detection signals having phases corresponding to a detected rotational position of the motor and different from each other, and a position detecting circuit detects a rotational position in a unit which is less than one cycle of the first and second detection signals based on the first and second detection signals, and outputs a rotational position signal representing a detected rotational position. Further, a motor controller compares the rotational position signal with a reference position signal representing a reference rotational position of the motor to obtain a position error, and controls the rotational position of the motor so that the position error is minimized.
