The vacuum cleaner motor (VACUUM CLEANER MOTOR) is the heart of the vacuum cleaner. The main types of vacuum cleaner motors are: dry vacuum cleaner motor (THRU-FLOW), dry and wet vacuum cleaner motor (BY-PASS). The vacuum cleaner motor consists of two parts: the motor part and the fan part. Because the vacuum motor has a high rotational speed requirement, it is generally between 20000-30000 rpm, so the motor mainly uses a series-excited motor, also called a series-excited motor.
There are copper wire motor and aluminum wire motor. Copper wire motor has the advantages of high temperature resistance, long life, long single operation time, etc., but the price is higher than aluminum wire; Aluminum wire motor has the characteristics of low price, but the temperature resistance is poor, the melting point is low, and the life is not as long as the copper wire.
The series-excited motor is mainly composed of a stator, a rotor, a front and a rear cover (cover) and a heat-dissipating fan blade. The stator is composed of a stator core and a winding sleeved on the pole piece, and the function is to generate a field magnetic flux, a magnetic flux and Supporting the front and rear covers; the rotor is composed of a rotor core, a shaft, an armature winding and a commutator, and its function is to ensure and generate a continuous electromagnetic moment, and the work is carried out by the rotating shaft to convert the electric energy into mechanical energy; the front and rear covers support the armature The fixed shaft and the rotor are fixed and integrated into one body. The rotating shaft, the front and rear covers must have sufficient strength to prevent the armature from resonating with the cover, causing vibration and danger. Generally, there are rolling or sliding in the front and rear covers. Bearing.
