YVF系列变频调速三相异步电动机
YVF SERIES INVERTER DUTY THREE PHASE ELECTRIC MOTOR
 随着电力电子技术的发展，交流变频调速系统也正在突飞猛进地发展。为了适应市场的需要，本公司开发了YVF系列变频调速三相异步电动机。其主要技术性能如下：
- 电动机调速范围广，5(3)~100Hz无极调速。5(3)~50Hz为恒转矩调速，2极电机恒功率调速频率为50~60Hz ，4极以上为50~100Hz；在矢量控制下的条件下，调速范围还可以扩大。
- 低速性能好。低速时转矩平滑，无爬行现象。
- 电动机的绝缘等级为F级，绝缘结构具有对变频器输出高载波频率电压的适应能力。
- 防护等级：IP55。（其中轴流风机部分为IP44）。
- 在结构上，YVF系列的安装尺寸与Y2系列相同，以便用户的配套和选用。电机采用了独特的冷却结构，使用单独的轴流风机，保证了电机在低频恒转矩长期运行时温升不超过允许值。
DESIGNED FOR THE DEMAND OF MARKET,YVF SERIES INVERTER DUTY THREE PHASE MOTORS ARE DEVELOPPING ACCORDING TO THE ADVANCED TECHNOLOGE.THE MAJOR PERFORMANCE ARE AS FOLLOWING:
- WIDE FREQUENCY RANGE. 5(3)~100Hz STEPLESS SPEED REGULATION. BELOW 50HZ (OR 60HZ) WITH CONSTANT TORQUE SPEED REGULATION, FOR 2P MOTOR, THE CONSTANT POWER SPEED REGULATIO RANGE IS 50-60HZ, FOR 4P MOTOR, WHICH IS 50~100HZ. WITH VECTOR CONTROL, THE SPEED RANGE WILL BE EVEN BIGGER
- THE MOTOR TORQUE SMOOTH AT LOWER SPEED AND THE MOTOR RUNS WITHOUT CREEP.
- INSULATION OF MOTOR IS CLASS F,WHICH IMPROVE IT’S RELIABILITY.
- IP55. (IP44 FOR THE AXIAL-FLOW VENTILATOR)
- IT’S OUTPUT, FOOT-MOUNTING DIMENSIONS AND CENTRAL HIGH ARE IN CORRESPONDENCE WITH THAT OF Y2 SERIES. ADOPTED THE SPECIAL COOLING CONSTRUSTION AND ASSEMBLED WITH THE AXIAL-FLOW VENTILATOR. SO IT HAS GOOD INTERCHANGEABILITY AND COMMONALITY.
