1. Hydraulic coupling mode. That is, a hydraulic coupling device is inserted between the motor and the load in series, and the size of the coupling force between the motor and the load is adjusted by the height of the liquid level, so as to realize the speed adjustment of the load;
2. Cascade speed regulation. The cascade speed regulation must adopt a winding asynchronous motor, and a part of the energy of the rotor winding is sent back to the power grid through rectification and inverter, which is equivalent to adjusting the internal resistance of the rotor, thereby changing the slip of the motor; Because the voltage of the rotor and the voltage of the power grid are generally not equal, so a transformer is needed for inverting to the power grid, in order to save this transformer, the form of infeed motor is generally used in the domestic market application, that is, a three-phase auxiliary winding is made on the stator, which specifically accepts the feedback energy of the rotor, and the auxiliary winding also participates in the work, so that the energy absorbed by the main winding from the power grid will be reduced, so as to achieve the purpose of speed regulation and energy saving
3. High and low mode. Since the high-voltage frequency conversion technology was not solved at that time, a transformer was used to reduce the grid voltage first, and then a low-voltage frequency converter was used to realize the frequency conversion; For the motor, there are two ways, one is to use a low-voltage motor; Another way is to continue with the original high-voltage motor, which requires the addition of a step-up transformer between the inverter and the motor.
