Product Description



Product Description
With the development of electric power technology, AC frequency conversion speed control system is also developing rapidly. In order to meet the needs of the market, our company has developed YVF series frequency-controlled three-phase asynchronous motors based on extensive research and collection of relevant information at home and abroad. The performance indexes and technical conditions of the motors are in accordance with IEC34-1, GB755 and IB/T 71.8-2014 international and national standards. The motors are characterized by low noise, low vibration, wide speed adjustment range and novel appearance, and can be used with various kinds of frequency conversion devices at home and abroad. It helps to save energy and realize automatic control.
Features: beautiful appearance, high efficiency and energy conservation, Class F insulation, protection level IP55, low noise, low vibration, reliable and stable operation.

Technical Specifications
