Basic Structure Of The Vacuum Cleaner Motor

　　The vacuum cleaner motor is the heart of the vacuum cleaner, which is composed of two parts: motor and fan. The motor of the vacuum cleaner has high requirements on the speed, generally at 20,000-30000rpm, thus universal motor is used in vacuum cleaner.

　　The universal motor is mainly composed of stator, rotor, front and rear cover and fan blade. The stator consists of stator core and winding on the pole boot, which is used to generate exciting flux and guide magnet, support the front and rear covers. The rotor consists of rotor core, shaft, commutator and armature winding, which is used to generate continuous electromagnetic torque and exchange electrical to mechanical energy by means of rotating shaft driving the load working. The front and rear covers support the armature, connecting stator and rotor. Generally, shaft、front and back covers should have enough strength to prevent resonance effects from armature and covers, and covers have rolling or sliding bearings.

　　After learning the basic structure of universal motor, we return to the fan of vacuum cleaner motor. The fan has two main components: impeller and diffuser. The impeller can produce wind. When the impeller is rotating at a high speed of 20,000 to 30000rpm, negative pressure is created at the air inlet making a vacuum, then creates suction; The diffuser, also known as the inducer, is mainly used to release the wind smoothly, which is produced by the impeller. The quality of diffuser air flue directly affects the efficiency of the vacuum cleaner motor.
