The variable frequency speed regulating motor is a kind of changing the power supply frequency to achieve the purpose of motor speed regulation. It is based on the principle (formula): n=60f/p where: n-per minute speed p-pole logarithm f-frequency (China Power Grid Standard is 50Hz)

It can be seen from the above formula that when the number of motor stages (P) is constant, the frequency is changed, the motor speed per minute (n) is inevitably changed (proportional), and the general frequency of the inverter is changed between 10-60 Hz (Hz), but It can also be extended to 5-100Hz. The inverter motor must be used with the inverter. At present, frequency control is widely used in the world because the variable frequency speed control motor has the following advantages:
1. High efficiency and remarkable energy saving;
2. The speed regulation smoothing can stepless speed regulation in the range of 5-100Hz.
3. When the low frequency starts, the torque has little impact on the load;
4, the starting current is small, no additional starting equipment;
5, small size, light weight, the installation size is the same as the Y series;
6. An axial fan is installed in the hood, which has a good cooling effect at various speeds;
7. Wide application range, constant torque operation below 50Hz, constant power operation above 50Hz;
8. The electromagnetic speed regulating motor has simple structure, reliable use and convenient maintenance.
