机房内安装有曳引机、导向轮、控制柜、限速器、总电源控制盒等。
Normally located on top of well (upper-placed machine room), machine room includes traction machine, diverter pulley, control cabinet, overspeed governor and main power control box.4-1-1 控制柜Control cabinet电梯控制柜安装在曳引机旁边，是电梯的拖动装置和信号控制中心。
如图4-1所示。
早期的电梯控制柜中有接触器、继电器、电容、电阻器、变压器、整流器等。
随着电脑、电子技术的飞越发展，VVVF控制技术、光纤通讯技术、串行通信、网络技术等在电梯上得到广泛应用。
大规模集成电路的应用使电梯控制柜体积越来越小，功能越来越强，可靠性越来越高。
目前的电梯控制柜大多由全电脑控制板和变频器组成，达到对交流电动机进行调频调压调速控制（VVVF）。
Located near traction machine, control cabinet serves as atrailing device and signal control center, as shown in figure4-1. Originally, control cabinet included contactor, relay,capacitor, resistor, transformer, and rectifier. With rapiddevelopment of computer and electronics as well as wideapplication of VVVF control technology, optical fibercommunication technology, serial communication andnetwork technology in lift, application of big scale integratedcircuit makes control cabinet smaller in size, stronger infunction and more reliable in operation. Currently, controlcabinet is composed of computer control panel and frequency inverter, to control AC motor in terms of frequency, voltage and speed (VVVF).2of 4-39控制柜的电源由机房的总电源开关(图4-2)引入，由控制柜接触器引出的动力线用电线管送至曳引机的电动机接线端子。
7TRACTION MOTOR 牵引电机8.1 General characteristics一般特性The traction motor 6 FRA 4567 B is a three phase asynchronous motor, 6 poles, squirrel cage motor. It is of the open type, cooled by air forced ventilation. This motor is similar as the one for the SNCF freight locomotive BB 427000.牵引电机6 FRA 4567 B是一种6极三相鼠笼式异步电机。
它为开放式，由空气通风冷却。
此电机类似于用于SNCF货运机车BB 427000的电机。
Each motor is force-ventilated by a separated bogie circuit ( one circuit per two motors ).每台电机均由一个隔离的转向架回路（每两台电机一个回路）进行强制通风。
The motor is nose suspended in the bogie. This arrangement is adopted for speeds up to 140 km/h. 电机以鼻式悬挂方式安装在转向架中。
对于140 km/h以下的速度采用此布置。
The choosen constructive solution leads to a bearing supporting the motor, located after the pinion. This ensures a very long bearing life span.所选择的构造方案形成位于副齿轮后对电机的轴承支撑。
这样可以使轴承保证非常长的寿命期。
