摘要： A permanent magnet electric machine comprises a stator provided with windings and a rotor disposed with an air gap between the stator and the rotor. A plurality of permanent magnets are arranged along and fixed to the circumference of the rotor. The angular circumferential extent of a surface of each permanent magnet facing the stator is determined so that an induced voltage in the machine has a waveform that approximates a sinusoidal waveform, to suppress the peak of the induced voltage.

摘要： A device for detecting a load torque using angle detectors fitted with a certain spacing on a shaft which is rotated by a drive source and on the basis of a relative angular difference of angles detected by the angle detectors. The device includes two rotary drums or discs fitted with a certain spacing on the drive side and load side of the shaft, with a plurality of magnetic poles for generating magnetic signals being formed on the surface thereof, and a magnetic sensor disposed to confront the surface of the rotary drums or discs, with magnetic resistance effect elements which vary in internal resistance in response to the magnetism of the magnetic poles being provided thereon. The amount of torsion created by the load on the load side of the rotary shaft is measured as a phase difference of outputs of the magnetic sensor, and the torque is detected in terms of the angular difference between the magnetic drums or discs. The device is operative to detect a torque in both storage and rotation, and capable of detection within a period of magnetic signal, whereby high-accuracy, high-resolution torque detection is made possible.
