• SUMMARIZE

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 all current and large torque of winging motor. JR、JZR、YR、YZR three phase winging stator ac asynchronous motor who use the starter of resistance、reaor、adjustable rheostat frequency sensitive rheostat、 liquild resistance starter、soft-starter all can choose “No Brush and no ring to stead.

• 產(chǎn)品優(yōu)點(diǎn)

無刷無環(huán)起動(dòng)器把傳統(tǒng)的、繁瑣的、多觸點(diǎn)元件組成的起動(dòng)裝置去掉，采用無刷無環(huán)運(yùn)行，操作簡單，安裝拆卸方便，可大大減少維修費(fèi)用，其優(yōu)點(diǎn)是：去掉滑環(huán)、碳刷、刷盒、刷盒支架、短路環(huán)及二次回路系統(tǒng)中的頻敏變阻器、交流接觸器、時(shí)間繼電器等元件，并可保持電機(jī)原有的運(yùn)行特性。

• ADVANTAGE OF PRODUION

No brush No ring starter remove the traditional 、complicated、multiconduion 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 conneor and time relay.

• 性能特點(diǎn)

無刷無環(huán)起動(dòng)器的工作原理是利用電動(dòng)機(jī)在起動(dòng)過程中，轉(zhuǎn)子電流頻率 fz 隨轉(zhuǎn)子轉(zhuǎn)速升高而降低的關(guān)系 fz=f1×S，當(dāng)轉(zhuǎn)子轉(zhuǎn)速由 0 上升到額定轉(zhuǎn)速 Ne 時(shí)，轉(zhuǎn)子電流頻率則從 50Hz 平滑地降至1~3Hz。起動(dòng)器阻 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 Xp=ωLP，同理，Xp 也減少。當(dāng)起動(dòng)結(jié)束后，sf1 很小，Zp 則降到很小甚至近似于，因此電動(dòng)機(jī)在起動(dòng)時(shí)，既能限制起動(dòng)電流，也能功率因數(shù)和起動(dòng)轉(zhuǎn)矩，是一種理想的起動(dòng)裝置。

• PERFORMANCE CHARAERISTIC

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 reduion of fz, rp will go down, reaance xp=ωLp, xp will reduce. when the starting finish, sf1 is very all, zp will go down to nearly zero, so when starting, it not only limit the current, but also improve power faor and torque, which is an ideal starting equipment.

• 安裝與接線

與WZR無刷自控電機(jī)軟起動(dòng)器方式一致。
此電動(dòng)機(jī)轉(zhuǎn)子出頭線有兩種：即50KW以上的電動(dòng)機(jī)轉(zhuǎn)子有6個(gè)出頭線（A-A、B-B、C-C），50KW以下的電動(dòng)機(jī)轉(zhuǎn)子只有3個(gè)出頭線，本公司生產(chǎn)的無刷無環(huán)起動(dòng)器也按功率大小，設(shè)有6個(gè)或3個(gè)接線柱。起動(dòng)器裝配完成后，將轉(zhuǎn)子的出線接在起動(dòng)器接線柱對應(yīng)位置（對于有六根出線的電動(dòng)機(jī)，應(yīng)將同一相的兩根導(dǎo)線，對稱地接在起動(dòng)器的兩個(gè)接線柱上）即可，具體接線如下圖所示。

• INSTALLATION AND CONNEION

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 conne the line to corresponding  location of binding post.
