   The vacuum cleaner motor is the heart of the vacuum cleaner. The main types of vacuum cleaner motor include: dry suction vacuum cleaner motor, dry and wet vacuum cleaner motor. Vacuum cleaner motor consists of two parts: the motor part and the fan part, because the vacuum cleaner motor speed requirements are high, generally in 20000-30000 rpm, so the motor is mainly used is a series of exciting motor, also known as series excitation motor.

   There are copper wire motors and aluminum wire motors.
The copper wire motor has the advantages of high temperature resistance, long life, long single operation time, but the price is higher than the aluminum wire. The aluminum wire motor has the characteristics of low price, but the temperature resistance is poor, the melting point is low, and the life time is not as long as the copper wire.

  The stator excitation winding and the armature (rotor) winding are connected in series, and both the direct current and the alternating current can be switched on, and the commutator is commutated.

  The series-excited motor is mainly composed of a stator, a rotor, a front cover, a rear cover (cover), and a heat-dissipating fan. The stator is composed of a stator iron core and a winding wound on a pole shoe, and its function is to generate excitation magnetic flux, magnetic permeability and Support the front and rear covers; the rotor is composed of the rotor core, shaft, armature windings and commutator, its role is to ensure and generate continuous electromagnetic torque, work through the shaft to drive the load, the electrical energy into mechanical energy; before and after the cover from the support armature , The fixed and the rotor are fixed together as a whole. The shaft, front and rear cover must have enough strength to prevent resonance between the armature and the cover, causing vibration and danger. Generally, there is rolling or sliding in the front and rear cover.

 The fan section has two main components: the moving impeller and the fixed impeller. The moving impeller is mainly generating wind. When the rotating impeller rotates at a high rotation speed of 20000-30000 rotations per minute, a negative pressure will be generated at the air inlet to form a vacuum. The formation of suction; fixed impeller, also known as the wind guide wheel, the main role is to make the wind generated by the moving impeller to release more smoothly, the impeller air duct is good or bad, directly affect the efficiency of the vacuum cleaner motor.

The scope of application of vacuum cleaner motors: various domestic industrial dry suction vacuum cleaners, wet and dry vacuum cleaners, central vacuum cleaners, industrial vacuum cleaners and various types of sweeping machines. In fact, vacuum cleaner motors are not limited to vacuum cleaners, such as bubble baths, spray paints, artificial snowflake on stage, agricultural machinery, etc. that require suction.
