Generally, the frequency is changed between 10-60HZ (Hz) by frequency converter, but it can also be extended to 5-100HZ. The variable frequency motor must be used in conjunction with the frequency converter. Frequency conversion speed regulation is widely used in the world because it has the following advantages:
1, high efficiency and remarkable energy saving;
2, speed regulation smoothness can stepless speed regulation in the range of 5-100HZ;
3. When starting at low frequency, the impact of torque parameter load is small;
4, the starting current is small, and no additional starting equipment is needed;
5, small size, light weight, and the installation size is the same as that of Y series;
6. An axial fan is installed in the wind hood, which has good cooling effect at various speeds;
7. Wide application range, it can operate with constant torque below 50HZ and with constant power above 50HZ;
8. Compared with electromagnetic speed regulating motor, it is simple in structure, reliable in use and convenient in maintenance.
Conditions of use
1. The ambient temperature shall not exceed -15℃~+40℃
2. The altitude does not exceed 1000m.
3. Motor protection grade IP44
4. Power supply voltage is 380 (220) V 10% and frequency is 50 (60) Hz 2%.
