3. Simple wiring, convenient grasp and low price;
4. There are stages of speed regulation, and the stage difference is large, so smooth speed regulation cannot be obtained;
5. It can be used in cooperation with pressure regulation and speed regulation and electromagnetic slip clutch to obtain high efficiency Sliding speed regulation characteristics. This method is applicable to production machinery that does not need stepless speed regulation, such as metal cutting machine tools, elevators, lifting equipment, fans, water pumps, etc.
2、 Variable frequency speed regulation method
Variable frequency speed regulation is a speed regulation method to change the frequency of motor stator power supply, so as to change its synchronous speed. The main equipment of variable frequency speed regulation system is the frequency converter supplying variable frequency power supply. The frequency converter can be divided into two categories: Communication constant current AC frequency converter and communication communication frequency converter. At present, AC constant current AC frequency converter is mostly used in China. Its features:

3、 Cascade speed regulation method
Cascade speed regulation refers to that adjustable additional potential is connected in series in the rotor circuit of wound motor to change the slip of motor and achieve the purpose of speed regulation. Most of the slip power is absorbed by the additional potential in series, and then used to generate additional devices to return the absorbed slip power to the power grid or convert energy for utilization. According to the slip power absorption and utilization mode, cascade speed regulation can be divided into motor cascade speed regulation, mechanical cascade speed regulation and thyristor cascade speed regulation. It mostly accepts the additional resistance in series of the rotor of the crystal wound asynchronous motor to increase the slip rate of the motor and the motor operates at a lower speed. The greater the resistance in series, the lower the speed of the motor. This party The equipment is simple and convenient to grasp, but the slip power is consumed on the resistance in the form of heating It is a step-by-step speed regulation with soft mechanical characteristics.

5、 Stator voltage regulation and speed regulation method
When the speed of the stator is different, a set of mechanical transformation curves can be obtained. Because the torque of the motor is proportional to the square of the voltage, it is the largest The torque decreases a lot, and its speed regulation range is small, which makes it difficult to apply the general cage motor. In order to expand the speed regulation range, voltage regulation and speed regulation should accept cage motors with large rotor resistance, such as torque motors specially used for voltage regulation and speed regulation, or frequency sensitive electricity in series on wound motors Resistance. In order to expand the stable operation range, when the speed regulation is 2:1_ Feedback control shall be adopted in the occasion to achieve the purpose of automatic speed adjustment. The main device of voltage and speed regulation is an energy supply At present, the commonly used voltage regulation methods of power supply responding to voltage changes include series saturation reactor, autotransformer and thyristor voltage regulation. Thyristor voltage regulation mode is the best. Characteristics of voltage and speed regulation:
1. The voltage and speed regulation circuit is simple and easy to realize automatic control; mountain
2. In the process of voltage regulation, the transfer differential power is consumed in the rotor resistance in the form of heating, and the / efficiency is low.
3. Voltage regulation and speed regulation are generally applicable to production machinery below 100kW.
