AC Universal Motor

The working principle of a series motor is similar to that of a DC motor, and its principle is explained through the left-hand rule and the right-hand rule. When powered by a DC power supply, current enters from the left coil, passes through the rotor winding, and flows out from the right coil. According to the magnetic effect of the current, the stator winding will generate a magnetic field in a direction from N to S in the figure. At the same time, the rotor winding that passes current will be affected by electromagnetic force, and the direction of the force can be determined according to the left-hand rule. The coils in the N-pole and S-pole ranges receive the same force, but in different directions. The electromagnetic torque will cause the rotor to start rotating. Due to the electromagnetic force and inertia, after the rotor rotates for half a revolution, due to the existence of the commutator, the direction of the current flowing into the rotor coil will change, so that the direction of the force within the N and S ranges will remain unchanged, and the rotor will continue to rotate. Go down.

In practical applications, series motors are widely used in power tools, kitchen supplies, floor care and other fields due to their advantages such as high speed, large starting torque, small size, and light weight.

A series excited motor is mainly composed of a stator, rotor, front and rear covers (covers), and cooling blades. The stator is composed of a stator core and a winding wrapped on pole shoes, which is used to generate excitation flux, conduct magnetism, and support the front and rear covers; The rotor is composed of a rotor core, shaft, armature winding, and commutator. Its function is to ensure and generate continuous electromagnetic torque, which drives the load to do work through the shaft, converting electrical energy into mechanical energy; The front and rear covers support the armature, connecting and fixing the stator and rotor together The rotating shaft and front and rear covers should have sufficient strength to prevent resonance between the armature and the cover, causing vibration and danger. Generally, there are rolling or sliding bearings inside the front and rear covers.

After understanding the basic structure of the series excitation motor, let's return to the fan part of the vacuum cleaner motor. The fan part mainly consists of 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 to 30000 revolutions per minute, negative pressure will be generated at the air inlet to form a vacuum, thereby forming suction force; The fixed impeller, also known as the guide vane, is mainly used to release the air volume generated by the moving impeller more smoothly. The quality of the fixed impeller air duct directly affects the efficiency of the vacuum cleaner motor. The application scope of vacuum cleaner motors: various household industrial dry vacuum cleaners, dual-purpose dry and wet vacuum cleaners, central vacuum cleaners, industrial vacuum cleaners, and various types of sweepers.
