YVF Variable frequency motor,frequency converter motor,induction electric motor

1. PRODUCT INTRODUCTION OF YVF ELECTRIC MOTOR

YVF series are asychronous 3 phase motors with variable-frequency and adjustable-speed ( frequency converter velocity modulation ),are INDUCTION MOTORs and ac motors. It has used a squirrel-cage construction.The electric motors have separately assembled with axial-flow ventilator, it guarantee its better cooling effect at different output.

The electric motors absorb the advantage of the same motors in the world.we use computer aided optimization design, the effect caused by the inverters’s higher-harmonic can be reduced as much as possible. The electric motors can be well matched with the inverter of different manufacturers in the world.Wide range of frequency conversion, speed control performance is superior.

The output rated power and mounting dimensions of the electric motors are perfectly in accordance with IEC60072-1. Convenient replacement and easy maintenance, strong universality and interchangeability. YVF electric motors have high efficiency, energy-saving, smooth drive, low noise, wide range of frequency, fast response, etc.

YVF series motors can be widely applied for driven equipment in need of velocity modulation in light industry, chemical industry, textile, oil, metallurgy, machine tools, CNC device. The motors can also be used to to fan and pump of energy-saving purpose, save considerable electric energy, protect the environment.
