Universal AC/DC motor

Abstract

The universal AC / DC motor consists of casing, two end caps, bearing seats fixed onto the end caps, hollow rotating shaft, electrodes and armature set inside the casing, and metal ring fixed to the rotation shaft. The motor has no cast iron casing and less temperature raise to damage the winding, light weight, high mechanism strength and wide application range.

Description

technical field [0001] The invention belongs to a motor, in particular to a general AC and DC motor. Background technique [0002] The motor currently used is fixed on the inner edge of the cast iron casing with a main pole composed of silicon steel sheets axially stacked and coil windings wrapped in grooves on it. The rotating shaft on the end cover is fixed with an armature composed of silicon steel sheets axially stacked and coil windings wound in grooves on the rotating shaft. The disadvantage of this kind of motor is that the magnetic conduction between the magnetic poles is completed by the cast iron casing. When the load of the motor increases or the running time is too long, eddy currents are easily generated in the cast iron casing, which will cause the temperature of the motor to rise. The coil is easily burned out; the cast iron casing has poor mechanical strength and is heavy, and the motor cannot work under vibration conditions, so the scope of application is g...

Problems solved by technology

The disadvantage of this kind of motor is that the magnetic conduction between the magnetic poles is completed by the cast iron casing. When the load of the motor increases or the running time is too long, eddy currents are easily generated in the cast iron casing, which will cause the temperature of the motor to rise. The coil is easy to burn out; the cast iron casing has poor mechanical strength and is heavy, and the motor cannot work under vibration conditions, so the scope of application is greatly limited
