The paper transferring mechanism includes a drive gear coaxially coupled with a rotation shaft of a motor, a pick-up gear coupled with a shaft of a pick-up roller to separately feed the paper sheets, and a feed gear coupled with a shaft of a feed roller to outwardly transfer the paper sheets.

一种纸张传送机构，包括：与一电动机的旋转轴同轴耦连的驱动齿轮，与一拾取辊的轴耦连以分别供给纸张的拾取齿轮，与一送纸辊的轴耦连以向外传送纸张的送纸齿轮。

The lathes are usually powered by electric motors which, through various gears, supply the necessary torque to the work material and provide the feed motion to the tool.

车床通常是电动机驱动的，通过不同的齿轮系统，向工件提供必要的扭矩，使刀具进行进给动作。

Indentation is too small, the two rolls of contact pressure is small, the paper feed roller and smaller tribochemical, in the same feed rollers under tension reducing motor speed ratio; the indentation is too large, it will be closing the rubber roller and feed roll in on the PTFE contact pressure greater as a result of excessive heat, accelerated ageing of rubber roller, reducing its life.

压痕过小，则两辊的接触压力较小，送纸辊与纸张的摩擦也较小，在相同的送纸辊电动机速比下张力减小；压痕过大，则会使橡胶合压辊与送纸辊在对压运转过程中因接触压力较大产生过多的热量，加速橡胶辊的老化，减少其寿命。

They have found wide application in large abd medium-sized winding asynchromous motors used in the rields of building materials,chemical industry,chemlcal fertilizer,paper making,pharmacy,metallurgical industry.

This paper presents several control methods for BLDC motor, and describes their fundamental principles ,advantages and disadvantages in brief. The method of speed-independent function,based on a new flux linkage function,is explained in detail. This method makes it possible to detect the rotor position over a wide speed range from near zero to high speed.

本文介绍了几种无位置传感器无刷直流电动机的转子位置检测方法，并对它们的基本原理，优缺点作了简单的说明，详细地阐述了基于一种新磁链函数之上的与速度无关的位置函数控制方法，利用这种方法从零转速到高转速的宽速度范围内能检测到转子位置。

Related modules in the toolbox of MATLAB/Simulink are adopted. The nonlinear mathematic model for SRM is obtained by adding the flux linkage functionψ into the parameter table of the motor module.

To meet the demand of power saving in oil production, a friction roller type intelligent pumping unit is developed based on the motor-reversing type pumping unit.

为了更好地实现节能目标，在满足油田采油工艺要求的前提下，在原有电动机换向智能抽油机的基础上，改进设计了滚筒式智能抽油机。

Air compressor is the necessary equipment for many enterprises. Since the air compressor might run for long time under the full-load status, the motor capacity is determined according to the maximum need, and the designed surplus is usually a little higher.

空压机组是很多企业的必备设备，由于空压机不能排除在满负荷状态下长时间运行的可能性，所以只能按最大需要来决定电动机的容量，设计余量一般偏大。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
