Established in 1989, Bluelight is a leading manufacturer of elevator control systems and gearless permanent magnet synchronous machines.

沈阳市蓝光自动化技术有限公司成立于1989年，是研发制造电梯控制系统和永磁同步无齿轮曳引机系列产品的专业公司。

According to the mathematical model and vector control method of permanent magnetic synchronous machine, the gearless elevator traction system was simulated.

并根据低速大转矩永磁同步电动机的数学模型及矢量控制方法，在MATLAB／SIMULINK环境中对无齿轮电梯曳引传动系统进行了建模和仿真。

Gearless traction machine and the power consumption compared to traditional lifts 30-40% reduction in the same period last year.

无齿轮曳引机的耗电量和传统电梯相比同比减少30-40%。

This paper introduces the design characteristics of low-speed permanent magnet synchronous motor for gearless pull-in system of elevator and design measures for suppression of the torque ripples at low speed ,presents the programming methods for the computer-aided design of PMSM using MATLAB,gives the test results of prototype motor,and verifies that the design idea and method are correct.

介绍了用于电梯无齿轮曳引驱动系统的低速永磁同步电动机的设计特点和抑制低速脉动转矩的设计措施，提出了建立在MATLAB平台上的永磁同步电动机计算机辅助设计程序的编程方法，给出了样机试制和试验的结果，证明了设计思想与方法的正确性。

Permanent magnet gearless traction machine is of the light weight,compact structure,small size,It cuts down the space required by the elevator.

永磁无齿轮曳引机重量轻，结构紧凑、尺寸小的特点，减少了电梯所需要的空间，方便了无机房电梯的井道布置。

But this synchronous gearless Tractor has no machanism slowdown framework and need too much moment. It can not depend on manual jigger to move lift car.

但是这种同步无齿轮曳引机没有了机械减速机构，要求的力矩很大，往往无法靠人力盘车来移动电梯轿厢。

Reliability:The gearless traction machine with low-speed moving parts ensures long-term reliability of the elevator.

可靠：富士永磁同步电机直接驱动的无齿轮曳引机只有低速成运动部件，保证电梯系统的长时间可靠运行。

The major bycatch species of sergestid shrimp mid-trawl and planktonic shrimp mid-trawl was Trichiurus lepturus, while the Harpadon microchir and Gerres filamentosus were the main bycatch species for bottom shrimp trawl and shrimp beam trawl, respectively.

四种渔业混获与目标渔获比为1.93~15.08，以桁杆式虾拖网最高，其余三种渔业皆在3.3以下，正樱虾及中型毛虾中层拖网混获最多的种类为白带鱼，底层虾拖网为小鳍镰齿鱼，桁杆式虾拖网为曳丝钻嘴鱼。

Initially for hunting, grazing, janitorial, and other service tracking and harness drag use.

最初供狩猎、放牧、守门、追踪和挽曳等役用。

Starting from the ground up, I used a high-traction rubber compound in the outsole together with a multidirectional herringbone design as the base.

从地面开始在，上面我连同一个多方向的飞鱼鱼骨一起用了外底的一个高曳橡皮化合物如基础的设计。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
