What is speed control motor?

A speed control motor is a kind of motor that changes the speed of the motor by changing the logarithm of the magnetic pole, voltage, current, frequency, etc., in order to achieve a higher performance of the motor.

Due to its excellent performance, speed regulating motor has been widely used in iron and steel, power stations, cable, chemical, oil, water, mud, textile, printing and dyeing, paper making, machinery, and other industrial sectors as a constant torque or decreasing the load torque mechanical step-less speed regulation, especially suitable for a great changing flow pump and fan class load moving in, can obtain good energy-saving effect.

Speed adjusting type

Frequency adjusting

Frequency conversion speed regulation is to change the frequency of the motor stator power supply, so as to change its synchronous speed regulation method. Frequency conversion speed control system is the main equipment to provide frequency conversion power converter, the converter can be divided into AC - DC - AC converter and AC - AC converter two categories, most of the use of ac - DC - AC converter. Its features:

1, high efficiency, no additional loss in the speed regulation process;

2, wide application range, can be used for cage asynchronous motor;

3, the speed range is large, hard characteristics, high precision;

4, complex technology, high cost, difficult maintenance;

5. This method is suitable for occasions requiring high precision and good speed regulation performance.

Voltage adjusting

When the stator voltage of the motor is changed, a set of different mechanical characteristic curves can be obtained, so as to obtain different speeds. Because the torque of the motor is proportional to the square of the voltage, the maximum torque decreases a lot, and the speed range is small, which makes the general cage motor difficult to apply. In order to expand the speed range, regulating voltage speed regulation should use cage motors with large rotor resistance value, such as torque motors for regulating voltage speed regulation, or in series on the winding motor frequency sensitive resistance. In order to expand the stable operation range, when the speed regulation is above 2:1, feedback control should be used to achieve the purpose of automatic speed regulation.
