Description

A kind of single-pole stator DC and AC universal electric machine

The invention belongs to electrical engineering

Present widely used various small-sized and micro ac motors, efficient is all low, and can not resemble direct current machine that works arbitrarily control or regulate rotating speed, though some alternating current machine also can the stepping speed governing or by the speed governing of the SCR control angle of flow.But its inefficiency method complexity.Optional equipment is many, and therefore general alternating current machine has only a kind of rotating speed, can not change speed and electromagnetic torque as required.Direct current machine is than alternating current machine efficient height, and the motor that produces various rotating speeds easily is next, and present general direct current machine needs commutator and brushgear to work, and this device is the weak link of direct current machine always, causes the machinery and the apparatus failure of motor easily.

Though micro brushless dc motor has been eliminated commutator and brush, can resemble and rotate the alternating current motor, but the starting of motor and at the uniform velocity rotation need multiple elements such as complicated electronic circuit and a plurality of large power triodes to work.So this motor not only costliness but also complexity, reliability is also poor, can only be applicable to special occasions.

It is simple to the purpose of this invention is to provide a kind of structure and manufacturing process, motor with low cost.This motor has overcome the deficiency of above-mentioned three kinds of motors, makes it have the advantage of two kinds of motors of AC and DC.Be a kind of multipurpose, high efficiency, the multiple power supply of adaptation, and the DC and AC universal electric machine that can carry out stepless speed regulation.

Concrete solution of the present invention comprises the structure and the manufacture method of single-pole stator DC and AC universal electric machine.
