    T 系列三相同步電動機



    系列三相同步電動機

    1. 概述  SUMMARIZE

    T 系列三相同步電動機 適用于傳動通風機、水泵、電動發電機組及其它通用機械。本系列電動機的額定電壓為10000V,根據用戶要求可制成6000V。額定功率因數為0.9(超前)。電動機允許全壓直接起動,起動時轉子回路應串接10倍于磁場繞組電阻的起動電阻。

    本系列電動機符合國家標準GB 755 《旋轉電機 定額和性能》的有關規定。

    T series synchronous motor are applied to drive fan,water pump,motor-generatoe set and other universal machines.Their rated voltage is 10000V or 6000V as the customer request.The frequency is 50 Hz.The rated power factor is 0.9(leading).The motor is allowed to be started directly at full voltage .The rotor circuit should be series connected with a starting resistor with ten times resistance of field winding resistance during strating.

    2. 結構簡介  INSTRUCTION OF CONSTRUCTION

    T系列電動機為臥式結構。冷卻方式有開啟自扇冷式、管道或半管道通風式、封閉自循環通風式。T系列電動機可制成一端軸伸,也可制成兩端軸伸。旋轉方向從集電環端看為逆時針方向旋轉,根據需要可改變電機的旋轉方向,但電機的風葉應做相應的變動。

    機座:用鋼板焊接成整體結構,機座與軸承座分別固定于鋼板焊成的底板上。

    定子鐵心:用0.5mm后的硅鋼沖片疊壓而成,定子鐵心用拉緊螺桿固定在機座上。

    定子線圈:線圈為疊繞組,采用F極絕緣,并有防電暈措施。線圈端部幫扎牢固,并經整體VPI真空浸漆處理。

    磁極:用薄鋼板沖制的磁極沖片疊壓而成,磁極鐵心外套以磁極線圈。整個磁極裝在磁軛上。

    磁極線圈:由銅扁線繞制而成,經絕緣處理后為F級絕緣。

    軸承:由鑄鐵的軸承座和澆有軸承合金的軸瓦等組成,潤滑方式為油環自潤滑或外加油路系統的復合潤滑。

    電刷與集電環:集電環為裝配式結構。電刷裝在恒壓刷盒內,由導電板連接起來,整個刷架固定在軸承側面。

    勵磁方式:本系列電動機勵磁系統采用可控硅勵磁裝置。勵磁裝置可由我公司配套提供。

    T series synchronous motor are of horizontal.Their cooling mode can be open self-ventilation,duct or half duct ventilation,or enclose self-circulating ventilation.T series synchronous motor can have one shaft endirection as see from the ring collector.The rotation direction can be changed,but the fan should be changed accordingly. Frame:Integral constrution welded by steel plate.The frame and plain bearing housing are fixed on the base by steel plate respectively. Stator iron core:Laminated by 0.5mm silicon steer lamination.The stator iron core is fixed on the frame by tighting screw ordoetail rib.

    Stator iron core:Laminated by 0.5mm silicon steer lamination.The stator iron core is fixed on the frame by tighting screw ordoetail rib.

    Stator coil:The coil is two layer lap winding.It has class F insulaioon and can prevent the corona.The end of the coil is wrapped tightly and be integral varnished.

    Magnetic coil:Wound by flat copper wire and has class F insulation after be insulating treat.

    Bearing:Composed of cast iron plain bearing housing and plain bearing half-liner casted with alloy.The lubricating method is oilring self-lubricating or compound lubricating with outer oil system.

    Brush and collector ring:The collector rings construction is assembling.The brush is fixed in the constant voltage brush box and connected by the conducting plate.The whole brushis fixed on the side of bearing.

     Exciting mode:T series synchronous electrical machines are excited by quiescent controllable exciting.The exciting unit can be procided by the manufactroy.
