Product Overview
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.
Changli’s YVF Series Frequency Controlled Three-Phase Asynchronous Motors are engineered specifically for optimal performance with frequency converters (VFDs). Offering high efficiency (IE2), robust design, and wide power range from 0.75 kW to 200 kW, these motors meet IEC standards with frames 80 to 315. The IP55 protection rating and TEFC enclosure ensure durability in various industrial environments.
Designed for seamless integration with frequency converters, enabling precise speed control and energy savings.
Support for frequent start-stop cycles without compromising motor life.
Complies with IE2 efficiency standards, reducing electricity consumption and operational costs.
Optimized electromagnetic design minimizes losses and heat generation.
Enclosure: Totally Enclosed Fan Cooled (TEFC) for enhanced protection against dust and moisture.
IP55 protection ensures resistance to water jets and dust ingress, suitable for industrial and outdoor applications.
Durable cast iron frame with precise machining for extended service life.
Ideal for pumps, fans, compressors, conveyors, and other variable speed industrial applications.
Compatible with common industrial VFD brands and control systems.
