YVF系列變頻調速三相異步電動機
YVF SERIES INVERTER DUTY THREE PHASE ELECTRIC MOTOR
 隨著電力電子技術的發展，交流變頻調速系統也正在突飛猛進地發展。為了適應市場的需要，本公司開發了YVF系列變頻調速三相異步電動機。其主要技術性能如下：
- 電動機調速范圍廣，5(3)~100Hz無極調速。5(3)~50Hz為恒轉矩調速，2極電機恒功率調速頻率為50~60Hz ，4極以上為50~100Hz；在矢量控制下的條件下，調速范圍還可以擴大。
- 低速性能好。低速時轉矩平滑，無爬行現象。
- 電動機的絕緣等級為F級，絕緣結構具有對變頻器輸出高載波頻率電壓的適應能力。
- 防護等級：IP55。（其中軸流風機部分為IP44）。
- 在結構上，YVF系列的安裝尺寸與Y2系列相同，以便用戶的配套和選用。電機采用了獨特的冷卻結構，使用單獨的軸流風機，保證了電機在低頻恒轉矩長期運行時溫升不超過允許值。
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.
