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 YSP/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
Frame size: 80 ~ 355mmWe have obtained such certifications as CE, CCC, EAC, ISO 9001, ISO 14001, ISO45001, etc. Our motor series comply with IEC, NEMA, GOST, ISO, IEEE, JIS, AS standards.
Located in Changsha, Hunan province, Changli Electric Co., Ltd. (formally known as Changsha Motor Factory, which was founded in 1946), is a leading electric motor manufacturer among Top 10 industrial electric motor manufacturers in China.
With an investment of 1094 million yuan, the company covers an area of about 400mu (about 270,000m2), has over 600 sets of precision production equipment, with annual production capacity of 8,000 MW.
