The series wound motor is mainly composed of stator, rotor, front and rear end covers (covers) and cooling wind blades.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.
Knowledge of the basic structure of the series motor, back to the vacuum cleaner motor fan, fan part mainly has two main parts: the impeller and impeller, and impeller wheel is mainly produce the wind, when the impeller wheel with a 20000-30000 revolutions per minute of the high speed rotates, into FengKouChu will produce negative pressure vacuum formed, and the suction;Fixed impeller, also known as the wind guide wheel, the main role is to make the air volume produced by the moving impeller more smooth release, the quality of the fixed impeller duct, directly affect the efficiency of the vacuum cleaner motor.
