电动机

Exactly the advance of these techniques make the motor control the technique at near two 10-year insides change for turn overing the ground of day is take placed.

正是这些技术的进步使电动机控制技术在近二十年内发生了天翻地覆的变化。

A: It means that a bottle without compressed air can be mounted on the machine, after the game starts; the electric power supply pre-mounted on the machine drives the motor of air compressor to build the air pressure into the bottle, then it can be used as a power source.

意思是指在比赛开始时，未充压缩空气的安在机器人身上的瓶子；提供给安在机器人上的空气压缩机的电动机，来把空气压缩进瓶子，这样才能被当作动力源使用。

The oil pump control system of governor oil pressure unit at power plant of Naban reservoir was modified with contact-free,soft start,intelligent pressure control unit,which not only remove the defects from traditional oil pump motor control mode consisting of relay and contactor,but also upgrade the control automation degree,improve starting performance and permit convenient operation.

通过利用无触点的智能软启动压力控制装置对那板水库电站调速器油压装置油泵控制系统的改造，解决了油泵电动机采用传统继电器———接触器控制方式所存在诸多缺陷，提高控制的自动化程度，改善启动性能，方便操控，经过3年多的应用，运行良好，为水电站的调速器油压装置油泵控制提供了一个好的借鉴。

Of the general testing items, dynamic performance is the most important and difficult one to be carried out, including pull-in/pull-out torque, pull-in/pull-out frequency, raising frequency time and so on.

在经常要进行的测试项目中，以步进电动机动态性能指标的测试最为重要。

In this system design method, voltage of the driver and design parameters of the motor are determined as the pull-out torque requires at the full-conducting frequency.

在该系统设计方法中，按照全导通频率处的牵出转矩来确定驱动器电压及电动机的设计参数。

As a sub- project of national science and technology key project——"The Research andDevelopment of High Performance Rare Earth Permanent Magnet Machine ", this paper presents the research on several key questions of designing premium-efficiency permanent magnet synchronous motor uses in the fan or pump ,such as efficiency, power factor, pull-out torque and so on. The achievement that has value in the Engineering is obtained.

作为国家重点科技攻关项目&高性能稀土永磁电机的研究与开发&的一个子课题，本文围绕风机、泵类负载用超高效永磁同步电动机设计中的效率、功率因数、失步转矩等几个关键问题进行了研究，取得了工程上具有使用价值的成果。

This enter and give system realize worker stock with two major basic functions that retreat soon mainly, To switch over and adopt getting automatically controlled, thus avoid between milling cutter and surface scotch that has process already when stopping speed.

其设计方案主要从总体方案设计、各主要部件技术参数的确定，及其空间的合理布置、传动方案的比较选择、各种典型零件的设计计算、校核、电动机选型等。进给系统作为机床的主要功能系统，对之有较高的运动速度，精度要求。

When high-strength sheet metal straightening,it will have a Turtle phenomenon,its process control model is obviously inadequate hydraulic pressing,the Shaft of straightening machine Often broken and the work of roller bearings damage Frequently.so it is necessary for the fuel tank pressure,displacement and the roll rotation of the motor current,torque drive signal for analysis.

当矫直高强度薄板时，会产生龟背现象，其工艺控制模型中液压压下明显不足和矫直机传动轴经常断，工作辊轴承经常损坏问题，于是很必要对液压缸压力，位移和各辊的电动机转数，电流，传动扭矩信号进行分析。

In a similar way, though not with the same precision, it is possible to calculate in advance the mode of operation of an electric motor, a transmission system, or of a wireless apparatus, even when dealing with a novel development.

同样，尽管精确程度有所不同，但还是可能事先算出电动机、输电系统、或者无线电装置的运转方式，甚至在处理比这些还要新的事物时也是这样。

In a similar way, though not with the same precision, it is possible to calculate in advance the mode of operation of an electric motor, a transmission system, or of a wireless apparatus, even when dealing with a novel development.

同样，尽管精确程度有所不同，但还是可能事先算出电动机、输电系统、或者无线电装置的运转方式，甚至在处理痹烩些还要新的事物时也是这样。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
