YEZ系列电动机是一种不附加任何电磁设备自行制动的电动机，具有结构紧凑体积小，重量轻等优点。设计和制造均符合国家有关规定的要求，2000年8月通过ISO9001国际质量认证。

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.

各部零件均经精密加工和检验，制动部分保证在满载情况下迅速刹住，停止转动，并能频繁的起动和运转。

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.

本系列电动机适用于快速制动与需要频繁制动的场合，加电动葫芦，电动小车及大车运行机构，仓库自动化及军训打靶设施等。

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.结构

Two. Structure

本系列电动机为自冷式，前端盖有连接法兰。

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

定子：定子铁心嵌完线以后，漆浸前进行冲击耐压试验一分钟，经浸漆烘干后成为一个完整体，绕组及绝缘具有良好的电气、机械、防潮性能及热稳定性。

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.

电动机的绝缘等级B级。

Motor insulation class B.

转子：采用热套工艺将铸铝转子固定在轴上，转子经校正平衡，运转平稳，振动小。

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

风扇制动轮及风扇罩：除0.2～0.8KW电机风扇制动轮采用铸铁件和铸铝件两种材料外，其它品种电机均采用ZL203（GB1173-84）铝合金制成，并配有石棉橡胶制动环。风扇罩由08F钢板拉伸后冲孔制成，风路畅通，外形美观，刚性好。

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.制动原理

Three. Braking principle

在电源接通时，转子轴向磁拉力克服弹簧力推开制动轮，电机旋转。切断电源、转子在弹簧力的作用下复位，制动环对电机制动而停止运行。

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.
