DREIPHASENRELUKTANZMOTOR.

摘要

A three-phase reluctance motor in which a rotor (1) is constituted to receive the magnetic attractive force in one direction at all times without cancelling the magnetic attractive force, in order to decrease mechanical vibration. Moreover, compared with the conventional motors, this motor has fewer magnetic poles (16a,---) and salient poles (1a,---), and thus it becomes a small-sized low-output motor. Three three-phase reluctance motors are accommodated in the same housing, the magnetic attractive forces in the radial direction of one reluctance motor at the centre and of two reluctance motors on both sides are balanced in the opposite directions relative to each other, so that a predetermined attractive force is left. Pairs of magnetic poles (16a,---) of each of the phases are excited to form N and S poles.
