YG、YGEJ系列三相異步電動機

YG系列輥道用三相異步電動機

YG SERIES THREE PHASE ASYNCHRONOUS MOTOR USED IN THE ROLLER WAY

YGEJ系列輥道用制動三相異步電動機

YGEJ SERIES THREE PHASE ASYNCHRONOUS MOTOR WITH BRAKE USED IN THE ROLLER WAY

  YG系列輥道用三相異步電動機采用封閉自冷式結構,是取代JG2系列電動機的更新換代產品。YG系列電動機按用途可分為YGa和YGb兩種型式,YGa型電動機具有堵轉轉矩大、動態常數高、機械特性軟的特點,能夠頻繁起動、制動和反轉運行,適用于單獨拖動冶金工業的工作輥道輥子。YGb型電動機具有功率大、效率高、機械特性硬的特點,通常只有單向運轉,適用于單獨動冶金工業的傳動輥子。

  YG系列電動機額定電壓380V,額定頻率50Hz,電機采用Y接法,可以滿壓起動。在保持電壓與頻率成正比變化的條件下,YGa型電動機允許在40Hz~70Hz范圍內使用(但堵轉轉矩和動態常數隨頻率變化而變化),YGb型電動機可以在10Hz~70Hz頻率范圍內作恒轉矩調速運行。YG系列電動機安裝尺寸符合IEC標準,外殼防護等級為IP54,冷卻方式為IC0041。YGa型電動機采用H級絕緣,YGb型電動機中心高112mm~200mm,采用F級絕緣,中心高225mm采用H級絕緣。YGa型電動機主要用于斷續工作制,按表1中的堵轉轉矩和相應于一定的負載持續率進行選用,負載持續率FC表示,分為15%、25%、40%、60%四種,其中40%為基準定額。YGb型電動機主要用于連續工作制,按表2的額定功率選用。

  YGEJ系列電動機是由YG系列電動機附加交流制動器組合而成。交流制動器無整流二極管,由三相380V電源直接供電,具有運行可靠,使用壽命長,制動速度快,定位準確,制動力矩可以從零調到需要值等優點。

  該系列變頻電機中自主研發交流制動器經推向市場獲得廣泛好評。

  本系列變頻電機可以按用戶提供的圖紙設計并制造。


YG Series 3-Phase Asynchronous Motor Used in the Roller Way adopts the self cooling construction, which replaced the pervious generation of JG2 series motors. This series motor can be divided into two sub-models, namely, YGa and YGb according to their usage. The YGa series motor is suitable for driving roller of the roller way in the metallurgical industry,as it has a large braking torque, high dynamic constant, soft mechanical performance, and suitable for frequently starting, stopping and inverting capacity. The YGb is used for driving the conveying roller in single direction in the metallurgical industry, due to it features large power, high efficiency and hard mechanical performance.

YG series motor is capable to start under normal voltage condition; therefore it is not necessary to reduce starting voltage, eg. It can be started at 380V and 50Hz. Under condition of the voltage changing in the positive proportion to the frequency, the YGa series motor is allowed to operate freely at range from 40Hz to 70Hz, while the braking torque and dynamic constant varying correspondent to the change of the frequency. The YGb series motor is capable to operate in variable speed and constant torque within the frequency range of 10Hz to 70Hz.

The mounting dimension of the YG series motor meets the IEC Standard. The protection for its outside layer is IP54, and cooling method is IC041. YGa adopts Class H insulation. However, YGb uses Class F insulation for frame height between 112mm to 200mm while Class H insulation for frame height of 225mm.

YGa series motor mainly operates non-continuous duty. Its duty cycle can be selected from one of duties corresponding to the braking torque shown in the table below. The ratio of duty cycle is represented as FC. It can be specified in 15%, 25%, 40% and 60%, among those ratio 40% is considered as the basic cycle. YGb series motor mostly operates under continuous duty. The selection of its duty cycle demonstrated in the table below.

Compared with YG Series 3-Phase Asynchronous Motor Used in the Roller Way, YGEJ Series 3-Phase Asynchronous Motor with Brake Used in the Roller Way has the same features and functions as YG series motors, but it is added a build-in AC brake. The AC brake is powered directly from a three phase power supply without rectified diodes. The AC brakes are not only quick response braking (100 times quicker than a DC single phase brake) but also have improved reliability and long service life. The advantages of AC brakes also include precise positioning, such as no axial movements, and the capability of a wide adjustable range of braking torque, such as from zero (0) to any desired values. The AC brake is an approved patent from the National Patent Bureau. The approval patent number is: 97206492.3.

Above series motors are available in the direct connection between the motor and the gearbox. Please refer to tables below for details.

These series motors can be customized designed and produced to meet your request.
