YVF2 SERIES FREQUENCY-CHANING AND SPEED-GOVERNING THREE-PHASE ASYNCHRONOUS ELECTRIC MOTOR Overview: YVF2 Series three-phase asynchronous motor is a high energy-saving motor. which is promoted mainly by the national Ninth Five-Year Plan. Operation Speed under control when have low speed (frequency below 50Hz) operate steadily. It has a upper stall torque and lesser stall current. motor has constant output power when it has high-speed. It has big Speed regulating , small vibration. low noise and match with a variety of SPWM frequency device in domestic constitute AC variable frequency stepless speed regulation system. Energy saving in more than 30%. It Can be used widely in driving principal axis of CNC machine tools. weaving, chemical industry. printing, plastics, metallurgy and other industries constant torque, constant power and fan speed, pump and so on speed regulation. It has the computer control interface. it help for speed control system to achieve automatic control. Motor with an independent axial fan, so that it has good cooling effect at different speeds. Brieg 一、Min frequency, torque at start> 125% 二、Frequency speed regulation scope 5 - 100Hz underthe vector control condition. The speed adjusting scope can be enlarged. 三、5-50Hz constant torque speed regulation. 50-100Hz constant power speed regulation
