摘要： A P-ECU controls an actuator which drives a shift control mechanism. An encoder signal acquisition unit acquires signals output from an encoder which detects a rotational angle of the actuator. A counter calculates a count value from the output signals of the encoder. An energization control unit controls energization to the actuator. A first phase-matching unit uses the Z-phase signal of the encoder to match the count value with energized phases so as to find a correspondence therebetween and a second phase-matching unit matches the count value with energized phases to find a correspondence therebetween without using the Z-phase signal of the encoder. If the first phase-matching unit detects an abnormality of the encoder, the second phase-matching unit subsequently performs phase matching.

摘要： In a torque sensor having a magnetic metal film with magnetic anisotropy attached to a torque transmission shaft, and an exciting coil and a pair of detector coils each installed near the magnetic metal film, outputs of the detector coils and a reference signal are respectively added in waveform adders when the exciting coil is energized by an exciting power source. Then, the outputs of the adders and the reference signal are respectively compared in phase in phase comparators, and the outputs of the comparators are respectively converted in voltage values. A differential amplifier amplifies a difference between the voltage values, and a torque detector detects direction and magnitude of the torque applied to the torque transmission shaft from polarity and magnitude of the difference voltage value, thereby enabling to accurately detect applied torque even when installed near noise-producing electrical equipment such as an electric power steering system.

摘要： A motor and a disk drive device having the disk drive motor are disclosed. A bearing bush is arranged on a motor mounting plate constituting a base for mounting on the disk drive device to read/write data from/into a recording disk. A shaft is supported rotatably through a bearing inside the bearing bush. A rotor on which an annular disk is placed is fixed at the upper end of the shaft. A rotor magnet is mounted on the inner peripheral wall surface of the rotor. A stator is arranged in opposed relation with the rotor magnet outside the bearing bush. The bearing bush is made of an aluminum alloy, the motor mounting plate is made of an aluminum alloy or a silicon steel plate, and the circuit board is formed of FPC. As a result, the heat generated in the motor can be efficiently radiated. Thus, the disk drive motor and the disk drive device having the motor are reduced in thickness and weight.
