YPF series(IP54) frequency-converting multi-speed three-phase induction motors (H80-315)
With the development of power electronic technology, a new method of speed regulation with the combination of the converter and the frequency-converting multi-speed motor is widely used to replace the traditional method of speed regulation. It can bring excellent the technical performance and significant economic benefits to various industry lines, and also can save energy, improve productive efficiency and automation degree.
Because of the particularity of converter supply, general purpose motors can not meet the requirements of running at high speed or low speed and fast dynamic response. So the special frequency-converting multi-speed motor must be used to in this case. Zhejiang Yongfa electro mechanics has done many research works on electromagnetism, insulation and ventilation according to the particularity of converter supply with the application of CAD, and marketed YPD series frequency-converting multi-speed motors.
With the features of lower noise, lower vibration, and wider speed range, YPF series motors can be matched with various kinds of SPWM frequency converting device. The motors can keep the constant torque for the frequency up to the 50Hz, and keep the constant output power for 50Hz upwads. They are distinguished by the stable speed regulation without torque ripple, high start torque, low star current, and therefore widely applied to various driving machines for speed regulation, such as light industry, textile, chemical industry, metallurgy, print, packing , food, machine tools, blowers, pumps and transportation lines.
