Brief description of industrial vacuum cleaner motor/motor/fan
Industrial vacuum cleaner motor/motor/fan (VACUUM CLEANER MOTOR) is an important core part of vacuum cleaners, and can also be called the heart of industrial vacuum cleaners. The main types of vacuum cleaner motors are: dry vacuum cleaner motor (THRU-FLOW), wet and dry vacuum cleaner motor (BY-PASS). Wet and dry vacuum cleaner motor Application range of vacuum cleaner motor: various household industrial dry vacuum cleaners, wet and dry vacuum cleaners, central vacuum cleaners, industrial vacuum cleaners and various types of scrubbers, sweepers, etc.
The industrial vacuum cleaner motor consists of two parts: the motor part and the fan part. Because industrial vacuum cleaner motors have high requirements for speed, generally 20,000-30000 revolutions per minute, the motors mainly use series motors, also known as series motors. . First of all, let us understand what a series motor is: The stator field winding and the armature (rotor) winding are connected in series, which can pass both DC and AC, and has a commutator commutating motor. Then, we are understanding the series The basic structure of the excitation motor: the series excitation motor is mainly composed of the stator, the rotor, the front and rear end covers (cover) and the heat dissipation fan. The stator is composed of the stator core and the windings sleeved on the pole shoes, and its function is to generate excitation Magnetic flux, magnetic conductivity and support front and rear covers; the rotor is composed of a rotor core, a shaft, an armature winding and a commutator. Its function is to ensure and generate continuous electromagnetic torque, and the load is driven by the rotating shaft to perform work, which converts electrical energy into mechanical energy; The front and rear covers support the armature and connect and fix the stator and rotor into one body. The rotating shaft, front and rear covers must have sufficient strength to prevent resonance between the armature and the cover, causing vibration and danger. Generally, the front and rear There are rolling or sliding bearings in the cover.
Finally, understand the fan part of the industrial vacuum cleaner motor. The fan part mainly has two main components: the moving impeller and the fixed impeller. The moving impeller mainly generates wind. When the moving impeller rotates at a high speed of 20000-30000 revolutions per minute , The air inlet will generate negative pressure to form a vacuum, and then form suction; the fixed impeller, also known as the air guide wheel, the main function is to make the air volume generated by the moving impeller more smoothly released, and the quality of the fixed impeller air duct directly affects The efficiency of the vacuum cleaner motor.
