No brush No ring starter is to conquer the default of the rings、carbon brush、and complex starting sets on winging asynchronous motor, and is an equipment to reserve the advantage that small current and large torque of winging motor. JR、JZR、YR、YZR three phase winging stator ac asynchronous motor who use the starter of resistance、reactor、adjustable rheostat frequency sensitive rheostat、 liquild resistance starter、soft-starter all can choose “No Brush and no ring to stead.
無刷無環起動器把傳統的、繁瑣的、多觸點元件組成的起動裝置去掉，采用無刷無環運行，操作簡單，安裝拆卸方便，可大大減少維修費用，其優點是：去掉滑環、碳刷、刷盒、刷盒支架、短路環及二次回路系統中的頻敏變阻器、交流接觸器、時間繼電器等元件，并可保持電機原有的運行特性。
No brush No ring starter remove the traditional 、complicated、multiconduction component starting equipment. it is easy to operate and install, less repairing expense. the advantage is: to keep the original operation without rings、carbon brush、brush box、brush box shell、short circuit ring and ajustable rheostat frequency sensitive rheostat on secondary loop system AC connector and time relay.

無刷無環起動器的工作原理是利用電動機在起動過程中，轉子電流頻率 fz 隨轉子轉速升高而降低的關系 fz=f1×S，當轉子轉速由 0 上升到額定轉速 Ne 時，轉子電流頻率則從 50Hz 平滑地降至1~3Hz。起動器阻抗 Zp=rp+jxp,其中鐵損 rp的大小與頻率的平方成正比，隨著 fz 的降低，rp也隨之下降，電抗 Xp=ωLP，同理，Xp 也減少。當起動結束后，sf1 很小，Zp 則降到很小甚至近似于零，因此電動機在起動時，既能限制起動電流，也能提高功率因數和增大起動轉矩，是一種理想的起動裝置。
The principle of starter is to use the current frequency of stator fz reduce when stator speed risingfz=f1xS, when the speed of stator rise 0 to rated speed ne, current frequency of stator from 50hz down to 1-3hz. of starter zp=rp+jxp, the size of iron loss rp is proportional to frequency square. with the reduction of fz, rp will go down, reactance xp=ωLp, xp will reduce. when the starting finish, sf1 is very small, zp will go down to nearly zero, so when starting, it not only limit the current, but also improve power factor and torque, which is an ideal starting equipment.
與WZR無刷自控電機軟起動器方式一致。
此電動機轉子出頭線有兩種：即50KW以上的電動機轉子有6個出頭線（A-A、B-B、C-C），50KW以下的電動機轉子只有3個出頭線，本公司生產的無刷無環起動器也按功率大小，設有6個或3個接線柱。起動器裝配完成后，將轉子的出線接在起動器接線柱對應位置（對于有六根出線的電動機，應將同一相的兩根導線，對稱地接在起動器的兩個接線柱上）即可，具體接線如下圖所示。
It is the same as WZR No Brush self-controlled motor soft starter.
There is 2 kind of out-head line of motor stator: 6 out-head line of more than 50KW motor stator(A-A、B-B、C-C). 3 out- head line of less than 50kw of stator. the starter also be designed 6-3 binding post according to power. after finishing the installation, pls connect the line to corresponding location of binding post.
