YEZ系列電動機(jī)是一種不附加任何電磁設(shè)備自行制動的電動機(jī)，具有結(jié)構(gòu)緊湊體積小，重量輕等優(yōu)點(diǎn)。設(shè)計(jì)和制造均符合國家有關(guān)規(guī)定的要求，2000年8月通過ISO9001國際質(zhì)量認(rèn)證。

YEZ series motor is a kind of motor which is not attached to any electromagnetic device, it has the advantages of compact size, light weight and so on. Design and manufacturing are in line with the requirements of the relevant provisions of the state, in August 2000 through the ISO9001 international quality certification.

各部零件均經(jīng)精密加工和檢驗(yàn)，制動部分保證在滿載情況下迅速剎住，停止轉(zhuǎn)動，并能頻繁的起動和運(yùn)轉(zhuǎn)。

All parts are by precision machining and inspection, ensure the braking part quickly stopped, under the full load condition to stop rotating, and frequent starting and running.

本系列電動機(jī)適用于快速制動與需要頻繁制動的場合，加電動葫蘆，電動小車及大車運(yùn)行機(jī)構(gòu)，倉庫自動化及軍訓(xùn)打靶設(shè)施等。

This series motor is suitable for fast braking and frequent braking situations, with electric hoist, electric car and traveling mechanism, warehouse automation and military training targeting facilities.

二.結(jié)構(gòu)

Two. Structure

本系列電動機(jī)為自冷式，前端蓋有連接法蘭。

The series motor is self - cooling, and the front end is connected with the flange.

定子：定子鐵心嵌完線以后，漆浸前進(jìn)行沖擊耐壓試驗(yàn)一分鐘，經(jīng)浸漆烘干后成為一個(gè)完整體，繞組及絕緣具有良好的電氣、機(jī)械、防潮性能及熱穩(wěn)定性。

After the stator stator core block end line, varnished before the impulse voltage test for a minute, after drying after a complete, winding insulation has good electrical, mechanical, thermal stability and moisture resistance.

電動機(jī)的絕緣等級B級。

Motor insulation class B.

轉(zhuǎn)子：采用熱套工藝將鑄鋁轉(zhuǎn)子固定在軸上，轉(zhuǎn)子經(jīng)校正平衡，運(yùn)轉(zhuǎn)平穩(wěn)，振動小。

The rotor: the cast aluminium rotor is shrunk on the shaft, the rotor adjusted balance, stable operation, small vibration.

風(fēng)扇制動輪及風(fēng)扇罩：除0.2～0.8KW電機(jī)風(fēng)扇制動輪采用鑄鐵件和鑄鋁件兩種材料外，其它品種電機(jī)均采用ZL203（GB1173-84）鋁合金制成，并配有石棉橡膠制動環(huán)。風(fēng)扇罩由08F鋼板拉伸后沖孔制成，風(fēng)路暢通，外形美觀，剛性好。

The fan wheel brake and fan cover: in addition to 0.2 ~ 0.8KW brake motor fan wheel made of cast iron and aluminum casting of two kinds of materials, other varieties of motor adopts ZL203 (GB1173-84) Aluminum Alloy made with asbestos rubber brake ring. The fan cover is made of 08F steel plate, which is made of punching and punching. The wind road is smooth, the appearance is beautiful, and the rigidity is good.

三.制動原理

Three. Braking principle

在電源接通時(shí)，轉(zhuǎn)子軸向磁拉力克服彈簧力推開制動輪，電機(jī)旋轉(zhuǎn)。切斷電源、轉(zhuǎn)子在彈簧力的作用下復(fù)位，制動環(huán)對電機(jī)制動而停止運(yùn)行。

When the power is switched on, the rotor axial magnetic pull overcomes the spring force to push away the brake wheel, and the motor rotates. Cut off the power supply, the rotor under the action of the spring force, the brake ring on the motor brake and stop running.
