The power train of armored face conveyor is repairable series-wound system. It consists of electrical motor, coupling, gearbox, sprocket assembly, chain assembly etc. The error of any part of power train will result in the failure of the whole system.

刮板输送机的传动系统由电动机、偶合器、减速器、链轮轴组、刮板链等组成，构成了整个传动链，任何一个部件的故障都会导致整个系统的失效，是可修复的串联系统。

In this way, the automatic control, the centralized control and the intelligent self-disposal functions of the motor protection is realized.

这样真正实现了电动机保护的智能保护、集中监控和管理。

The reason of low system efficiency of the mechanical lifting is: unavailable match between transformer and asynchronous motor with large capacity of equipment and large self-consumption; large average no load less of Y series electrical machinery (31.4% of the total oilfield electrical machinery) with 2.86kw; limited adjustable extent of stroke of the electrical machinery in low-liquid produced wells with minimum value of 4 times per minute for limitation of minimum rotation of the electrical machinery and minimum arc of contact of pulley. Energy consumption will be waste for 1 to 1.5 times per minute is enough.

分析显示，造成抽油机系统效率低的原因主要是：变压器与异步电动机之间匹配方式不合理，设备容量大，自身损耗大；占油田电机总量31.4%的Y系列电机的平均空载损耗大，为2.86kW；低产液井电机的冲次可调范围有限，受电机最低转度和皮带轮最小包角限制，其最小冲次仅可调到4次／min，但1~1.5次／min的冲次即可满足生产需要，造成能耗浪费。

In recent years, as numerical control technique has been applied, the newly electrical screw press with numerical control has emerged.

其中电动螺旋压力机采用电动机直接驱动的传动方式，代替以往广泛采用的液压伺服和机械传动方式，具有传动链短、易于维护等优点。

Machine drive principle: No matter it is mono-block type or detached type, we take electromotor as original motor to convey the power to retarder input shaft (high-speed rotation axle) through direct connection or triangular belt and retarder output shaft (low-speed rotation shaft) connects directly with the joint screw or low-speed rotation shaft connects with the main shaft joint screw through coupling thrust bearing socket.

机械传动原理：本司产品无论是整体式的还是分体塑料再生机，均以电动机为原动机，通过直连式或三角带将电动的力传递给减速器轮入轴由减速器输出直通联接螺杆或经低速轴通过联轴器止推轴承座主轴联接螺杆，使螺杆按设计要求及生产工艺要求的扭矩和转速匀速地旋转，以达到塑料塑化后定压、定量、均匀地连续挤出的目的。

Choice the motor according to the gear program and the job requirements of the rolling machine

根据传动装置的总体设计方案和轧车的工作要求选择电动机

With ecorner,electric motos will ensure contact between the wheel and the road.

有了& ecorner &系统，电动机将确保车轮和路面接触。

The frequency of the current ripple in the DC motor caused by its counter-EMF is analyzed.

0引言电动机的电枢是一个特殊的旋转体，旋转时有些电气参数会随转速而变。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
