Variable speed principle editing
The speed of the motor is changed by changing the connection mode of the windings, that is to say, the rotation speed of the motor is changed by changing the logarithm of the magnetic poles of the rotating magnetic field of the motor.
Two-speed motor (fan), usually the speed is low, sometimes the fan on high speed, mainly through the following external control line switch to change the winding connection of the motor coil to achieve.
1. There are two common windings with different pole logarithms embedded in the stator slot, and the pole logarithms can be changed by changing the connection method of the motor stator windings through switching of external control lines;
2. Two independent windings with different logarithms of poles are embedded in the stator slot;
3. There are two independent windings with different logarithms of poles embedded in the stator slot, and each winding can have different connections.

The two-speed motor belongs to the asynchronous motor pole-changing speed regulation, which is to change the pole number of stator rotating magnetic field by changing the connection method of stator windings, so as to change the speed of the motor.
According to the formula; N =60f/p shows that the synchronous speed of the asynchronous motor is inversely proportional to the logarithm of the magnetic poles. If the logarithm of the magnetic poles is doubled, the synchronous speed n decreases to half of the original speed, and the rated speed n of the motor will also decrease by approximately half. Therefore, changing the logarithm of the magnetic poles can achieve the purpose of changing the speed of the motor. This speed regulation method is graded, not smooth speed regulation, and only suitable for squirrel-cage motor.
This figure introduces the most common single winding two-speed motor, the speed ratio is equal to the magnetic pole multiple inverse ratio, such as 2 pole /4 pole, 4 stage /8 pole, from the stator winding delta connection method to YY connection method, the number of magnetic pole from 2p=2 to 2p=1.

Industry status editor
Two-speed motors are mainly used in coal mine, petroleum and natural gas, petrochemical and chemical industries. In addition, it is widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other sectors. As the main power equipment, the two-speed motor is usually used to drive pumps, fans, compressors and other transmission machinery.
With the development of science and technology and production, the places where there is the risk of explosion are also increasing. For example, edible oil production used to use the traditional pressing process, after the 1970s, China began to introduce foreign advanced extraction process, but this process to use a chemical solvent containing ethane, ethane is flammable and explosive substances; As a result, the leaching workshop becomes an explosion hazard site, requiring the use of two-speed motors and other explosion-proof electrical products. For example, in recent years, China's highway development is rapid, a large number of fuel gas stations appear, also provides a new market for two-speed motor.
