In some special driving circuits, two-speed motors are needed. Sometimes even a three - or four-speed electric motor is required. The principle and control method of these multi-speed motors are basically the same. Here is a small series with Senli motor to understand the content of the two-speed motor.
Two-speed motorIt is mainly used in various transmission machinery such as machine tools, mining, metallurgy, textile, printing and dyeing, chemical and other industries that require speed regulation step by step with the nature of the load. The requirement of the same motor to achieve multiple speeds is solved by different connections of the same winding and multiple sets of windings of the same motor.
The method of variable stage speed regulation is to change the number of magnetic poles of the motor by changing the connection mode of the stator winding of the motor, so that the synchronous speed can be changed successively and the motor speed can be adjusted successively. This kind of speed regulating motor currently has a fixed series of products to choose from, such as single-winding multi-speed motor.
Advantages: no additional slip loss, high efficiency; Simple control circuit, easy maintenance, low price; Smooth speed regulation with high efficiency can be obtained by combining with electromagnetic slip clutch.
At present, in the industrial field, there are many occasions that need speed regulation, such as driving, fans, conveyor belts, machine tools, etc., the use of pole change speed regulation has the characteristics of low cost, low power consumption, and good output torque rigidity.Two-speed motorThere is still some room for application.
