titleOfInvention | Position detecting device, synchronous motor using the same, vehicle driving device for four-wheel drive, and vehicle driving device for hybrid vehicle |
abstract | A position detection device capable of reducing the cost and space of a position detector, and a synchronous motor using the position detection device. A synchronous motor includes a rotor having a pair of cores having a plurality of claw magnetic poles, and pole cores in which claw magnetic poles of each core are alternately arranged in the rotation direction. Of one pair of cores, one of the cores has a magnetic part and a nonmagnetic part alternately, thereby forming a magnetic body. The magnetic sensor unit 200 includes magnetic yokes 210 and 230 that form a magnetic circuit including the magnetic part of the rotor in the magnetic path, a permanent magnet 240 that biases the magnetic circuit, and a magnetic circuit that is disposed by the permanent magnet. When the circuit is biased, a magnetic sensor 220 that detects a change in magnetic flux density that occurs when the magnetic part and the non-magnetic part of the magnetic body periodically cross the magnetic circuit as the magnetic body rotates is provided.
