Pole-changing Multi-speed Three-phase Asynchronous Motor

"pole-changing multi-speed three-phase asynchronous motor". This kind of motor is based on the three-phase asynchronous motor, by changing the connection mode of the stator winding to change the pole number of the motor, so as to achieve a variety of different speed operation. 

How it works:

When the pole-changing multi-speed three-phase asynchronous motor works, the stator winding passes through the three-phase symmetrical alternating current, which generates a rotating magnetic field between the stator and the rotor. The rotating magnetic field cuts the rotor winding and generates induced electromotive force and current in the rotor loop. The current in the rotor conductor is subjected to the action of the rotating magnetic field to make the rotor rotate. On this basis, the variable pole multi-speed three-phase asynchronous motor, by changing the connection mode of the stator windings, makes the stator windings form different pole numbers, and then changes the rotating magnetic field speed, and finally realizes the motor running at different speeds.

Features:

Wide speed range: can provide a variety of different speed options to meet the needs of different loads and work scenarios, such as machine tools, mining, metallurgy, textile and other industrial sectors of all kinds of universal, combination, special metal cutting machine tools and need to speed up various transmission mechanisms.

Equipment simple and reliable: Pole-changing multi-speed three-phase asynchronous motor pole change speed regulation method is relatively simple, do not need complex speed regulation device, high reliability of operation.

Good energy saving effect: Pole-changing multi-speed three-phase asynchronous motor can adjust the speed according to the change of load, so that the motor can maintain a high efficiency under different working conditions, so as to achieve the purpose of energy saving.

Application scenario:

Machining equipment: In the machine tool industry, different processing processes require different speed, variable pole multi-speed three-phase asynchronous motor can quickly switch speed according to processing requirements, improve processing efficiency and quality.

Lifting and transportation equipment: such as the trolley amplitude changing mechanism of the tower crane, the motor needs to provide different speeds in different working stages, and the variable pole multi-speed three-phase asynchronous motor can well meet this demand.

Ventilation equipment: In the ventilation system, according to different ventilation requirements, the air volume of the fan can be adjusted by changing the speed of the Pole-changing multi-speed three-phase asynchronous motor to achieve energy-saving operation.
