The carbon brush of the motor and the carbon brush of the generator are also collectively referred to as the carbon brush of the motor or the motor brush, the appearance of the carbon brush of the motor is a bit like the rubber strip that erases a pencil, there is lead lead on the top, the volume has big and small.For a 220V vacuum cleaner
The motor is mainly composed of a stator, a rotor, a front and rear end cover (hood) and a cooling wind blade.The rotor is composed of rotor core, shaft, armature winding and commutator. Its function is to ensure and generate continuous electromagnetic torque, drive the load to do work by rotating the shaft, and convert electrical energy into mechanical energy.The front and rear enclosures are used to support the armature and to secure the connection between the stator and rotor. The rotating shaft and the front and rear enclosures should be strong enough to prevent the armature from resonance with the enclosures, causing vibration and danger. Generally, there are rolling or sliding bearings in the front and rear enclosures.
1. The rotor is made of high temperature enameled copper wire, which is more heat-resistant and can improve the service life of the motor.
2. Ball bearing is used at the front of the motor to make it run more smoothly and reduce the noise of the motor.
3. The motor is equipped with a radiator blade, which can dissipate heat quickly and improve work efficiency.
4. Rotor overbalance test to reduce motor vibration and noise.
