The speed regulation methods that do not change the synchronous speed are widely used in the production of machinery, including the rotor series resistance speed regulation, chopper speed regulation, cascade speed regulation and the application of electromagnetic slip clutch, hydraulic coupling, oil film clutch and so on. The multi-speed motor that changes the synchronous speed changes the stator pole number, and the variable frequency speed regulation that changes the stator voltage and frequency can speed regulation of the non-commutating motor. The following is andThree-phase asynchronous motor manufacturersLet's find out.

       From the point of view of energy consumption during speed regulation, there are two kinds of efficient speed regulation methods and inefficient speed regulation methods:

       Efficient speed regulation refers to the constant slip rate, so there is no slip loss, such as multi-speed motors, frequency conversion speed regulation and speed regulation methods that can recover slip loss (such as cascade speed regulation, etc.).

       The speed regulation method with slip loss belongs to low efficiency speed regulation, such as the rotor series resistance speed regulation method, the energy is lost in the rotor loop; Speed regulation method of electromagnetic clutch, energy loss in the clutch coil; Hydraulic coupler speed regulation, energy loss in the hydraulic coupler oil.

       Generally speaking, slip loss increases with the expansion of speed regulation range, if the speed regulation range is not large, the energy loss is very small.

       Winding asynchronous motorAdditional resistance is inserted into the rotor to increase the slip rate of the motor, and the motor runs at a lower speed. The greater the resistance in the series, the lower the speed of the motor. This method has simple equipment and convenient control, but the slip power is consumed on the resistor in the form of heat, it is a step speed regulation, and the mechanical characteristics are soft.
