摘要： When a shaft misalignment detection part detects occurrence of a shaft misalignment that is a misalignment in a relative position in a radial direction of a rotary shaft between a magnet part and a sensor part, the shaft misalignment detection part outputs a shaft misalignment determination flag to a correction part and a control change instruction part. The correction part calculates a motor rotational angle so as to reduce a detection error caused by the shaft misalignment. The control change instruction part outputs instructions of changing calculation methods so that influence by the detection error decreases to an assist torque setting part and an assist current instruction part.

摘要： When a current sensor fails, instead of a normal-time motor control section, an abnormal-time motor control section drives and controls a motor. The abnormal-time motor control section detects a timing at which motor current becomes zero in a state in which all the switching devices are turned off. Every time the motor current becomes zero, the abnormal-time motor control section sets an ON time corresponding to steering torque, and turns on the switching devices corresponding to the direction of the steering torque for the ON time. With this operation, an average current corresponding to the steering torque flows through the motor, whereby deterioration of the followability of steering assist is suppressed.

摘要： A first excitation AC signal (V1=A1·sin(ωt)) is supplied to a first excitation coil of a first resolver via a first excitation line, and a second excitation AC signal (V2=−A2·sin(ωt)) is supplied to a second excitation coil of a second resolver via a second excitation line. Within a resolver unit, a first excitation line and a second excitation linea are connected via an electric resistance element. By virtue of this configuration, torque can be detected even when any of a ground line, a first excitation line, and a second excitation line of a wire harness is broken.

摘要： An electrical power supply unit for vehicle comprises: a Main Power Supply 100, a Voltage Converter 40 for converting the output voltage of the Main Power Supply 100 to supply electrical power to a Motor Drive Circuit 30, a Subsidiary Power Supply 50 to be charged by the Voltage Converter 40 and to aid the electrical power supply for the Motor Drive Circuit 30 with its stored electrical power, and an Electrical Power Supply Control Unit 62 to control the converted voltage of the Voltage Converter 40. The Electrical Power Supply Control Unit 62 controls the converted voltage of the Voltage Converter 40 based on the Voltage Converter Temperature Tb and the Subsidiary Power Supply Temperature Ts so that the heat generation condition of the Voltage Converter 40 and the heat generation condition of the Subsidiary Power Supply 50 are balanced. Thereby, the difference between the timing when a Voltage Converter Temperature Tb reaches an overheat prevention starting temperature and the timing when a Subsidiary Power Supply Temperature Ts reaches an overheat prevention starting temperature decreases, and the timing when an overheat prevention starts can be delayed as much as possible.

摘要： A magnetic head is composed of a write head which magnetically records information by emitting magnetic flux, which is generated by a write coil, from a magnetic pole unit to a recording medium; and a read head having a reading element which converts record magnetic flux, which is emitted from the recording medium, to an electric signal. In a write coil facing area facing an area in which the thin-film coil pattern of the write coil is disposed, a heater coil which causes a medium facing surface to protrude toward a recording medium side by thermal expansion caused by power distribution and overheating is disposed via an insulating layer. In the heater coil, a wide terminal pattern is disposed outside the write coil facing area, and a heater pattern having a width narrower than the terminal pattern is disposed in the write coil facing area.

摘要： A magnetic head structure has a coil and a magnetic pole allowing a magnetic flux generated by the coil to be transmitted therethrough and forming a magnetic gap. An insulating layer surrounds the coil, and a protective layer covers the insulating layer and the magnetic pole. The insulating layer has a volume equal to or greater than a value which is determined with respect to a thickness of the protective layer. It is preferable to increase the volume of the insulating layer as the thickness of the protective layer is made greater. By increasing the volume of the insulating layer, the protrusion of a portion of a floating surface of the magnetic head slider near the magnetic pole, toward the disk, is reduced.
