When we are in production, we often use three-phase asynchronous motors, and some mechanical equipment has this speed regulation demand, so today, Senli Motor Xiaobian will take you to simply understand the three ways of speed regulation of asynchronous motors!

       The first type of speed regulation is frequency conversion speed regulation, which is by changing the frequency of the motor stator power supply, so as to change its synchronous speed regulation method;

       The second type of speed regulation is pole logarithm speed regulation is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps, etc., for the magnetic pole number is changed in pairs, so it is a level adjustment method, generally can be two-speed, three-speed or four-speed speed regulation. The machine tool is often used to change the triangle connection to the double star connection, which is used to adjust the two-pole speed of the motor from four poles to two poles.

       The third type of speed regulation is cascade speed regulation, which is suitable for fans, pumps and rolling mills, mine elevators and extruders.
