摘要： A motor drive device includes a drive controller for generating drive signal “trq”, a limiter for limiting a value of drive signal “trq” within a range, a limit value generator for generating limit value “lmt”, and a drive output section for generating an energizing signal in response to an output signal from the limiter. The limit value generator generates a comparison signal by adding offset value “ofs” to drive signal “trq” and updates limit value “lmt” based on a size relation between a value (trq+ofs) of the comparison signal and limit value “lmt”.

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.

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.
