China motor vacuum cleaner factory, vacuum cleaner motor has copper wire motor and aluminum wire motor.Copper wire motor has the advantages of high temperature resistance, long life, long single operation time, but the price is higher than aluminum wire;Aluminum wire motor has the characteristics of low price, but the temperature resistance is poor, low melting point, life is not as long as copper wire.
Series wound motor is mainly composed of stator, rotor, front and rear end cover (cover) and cooling blade.The stator is composed of the stator core and the winding set on the pole boot, whose role is to generate excitation flux, magnetic conductivity and support the front and rear cover;The rotor is composed of rotor core, shaft, armature winding and commutator. Its role is to generate continuous electromagnetic torque, which drives the load to do work through the rotating shaft and converts electric energy into mechanical energy.The front and rear covers support the armature and fix the stator and rotor together.Among them, the rotating shaft, front and rear cover should have enough strength to prevent the armature from resonance with the cover, causing vibration and danger.Generally there are rolling or sliding bearings in the front and rear cover.
