T 系列三相同步电动机



系列三相同步电动机

1. 概述  SUMMARIZE

T 系列三相同步电动机 适用于传动通风机、水泵、电动发电机组及其它通用机械。本系列电动机的额定电压为10000V,根据用户要求可制成6000V。额定功率因数为0.9(超前)。电动机允许全压直接起动,起动时转子回路应串接10倍于磁场绕组电阻的起动电阻。

本系列电动机符合国家标准GB 755 《旋转电机 定额和性能》的有关规定。

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. 结构简介  INSTRUCTION OF CONSTRUCTION

T系列电动机为卧式结构。冷却方式有开启自扇冷式、管道或半管道通风式、封闭自循环通风式。T系列电动机可制成一端轴伸,也可制成两端轴伸。旋转方向从集电环端看为逆时针方向旋转,根据需要可改变电机的旋转方向,但电机的风叶应做相应的变动。

机座:用钢板焊接成整体结构,机座与轴承座分别固定于钢板焊成的底板上。

定子铁心:用0.5mm后的硅钢冲片叠压而成,定子铁心用拉紧螺杆固定在机座上。

定子线圈:线圈为叠绕组,采用F极绝缘,并有防电晕措施。线圈端部帮扎牢固,并经整体VPI真空浸漆处理。

磁极:用薄钢板冲制的磁极冲片叠压而成,磁极铁心外套以磁极线圈。整个磁极装在磁轭上。

磁极线圈:由铜扁线绕制而成,经绝缘处理后为F级绝缘。

轴承:由铸铁的轴承座和浇有轴承合金的轴瓦等组成,润滑方式为油环自润滑或外加油路系统的复合润滑。

电刷与集电环:集电环为装配式结构。电刷装在恒压刷盒内,由导电板连接起来,整个刷架固定在轴承侧面。

励磁方式:本系列电动机励磁系统采用可控硅励磁装置。励磁装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.
