一YCT 系列电磁调速电动机
YCT Serles Electromagnetic Adjustable Speed Motor
□ 概述
YCT 系列电磁调速电动机是机械工业部组织设计的Y 系列异步电动机的主要派生系
列。电磁调速电动机由拖动电机（Y 系列电动机）、电磁转差离合器和控制器三部份组成，
可用于恒转距负载场合，特别适宜在递减转矩负载中使用（例如离心式水泵和风机），有较
明显的节能效果。
YCT 系列电磁调速电动机能在规定的调速范围内均匀地、连续地无级调速，并能输出
额定转矩，电机在运行中当负载转矩变动时可通过控制器的速度负反馈系统自动调节离合器
的励磁电流，使输出转速基本上保持不变。
本系列电机有全国统一的技术条件，并且外形安装尺寸、拖动电机及其它易损件全国各
生产厂均为统一，可以互换。
□ Description
The YCT series electromagnetic andjustable speed motor is one of the derived series from Y
series asynchronous motor,which is designed under the organization of the Minstry of Mechaical
& Electronic Industries of the PRC The electromagnetic adjustable speed motor is composed of
three parts, ie. The driving motor (Y series motor) electromagnetic slip coupling and controller. It
is usually used under a constant torque load and is particularly suitable for the use under the load
with a decreasing torque such as the centrifugal pump and blower, etc. featuring evident
energy-saving efficiency.
The speed of the electromagnetic adjustable speed motor can be adjusted uniformly
continuously and steplessly within the specified adjustable speed range with an output of rated
torque. When the loading torque is changed during the running of the motor, the exciting current
of the coupling can be reguated automatically by the speed negative feedback system of the
controller so as to keep the output speed free of any variation basically.
There is a State Standard for the technical specifications of YCT series motor. Besides, the
overall & installation dimensions, driving motor, other easy-wearing parts of the motor in YTC
series are the same even if they are made by different domestic manufacturers, featuring high
exchangeability.
□ YTC 系列电机的特点：
1． 无失控区；
2． 调速范围广，速度调节平稳；
3． 具有速度负反馈自动调节系统，转速变化率小；
4． 起动力矩大，起动平稳；
5． 结构简单、可靠、使用维护方便；
6． 控制功率小，并能实现多种方式控制。
□ Features of YCT series motor:
a. Free of out-of-control zone;
2
b. Wide adjustable speed range and stable speed dajustment;
c. With sped negarive feedback automatic regulation system, small speed variation ratio;
d. Large start torque and smooth start performance;
e. Simple construction, reliable and easy for operation and maintenance;
f. Small control power, multi-way control.
□ 应用范围：
YCT 系列电磁调速电动机，可用于油漆流水线、装配流水线的传输带、注塑机、印染
机、印刷机、水泵、鼓风机、回转炉、拉线机、卷纸机、卷板机、压延机、空调设备、输送
设备等。
□ Applications:

□ 订货须知
1、用户选用于本系列电机时，应使选用电机的额定转矩大于或等于负载转矩。
2、订购时须说明产品型号，标准功率，调速范围，是否需要控制器，测速发电机为何
种等。
例：YCT160－4B，3KW.1250~125r/min 单机运行，不需附控制器，中频测速发电机。
又例：YCT250-4A,18.5KW.1320~132r/min 四台齐速运行，脉冲测速发电机。
3、如需要特殊型式或特殊规格的YCT 系列电机，请先于联系，根据具体情况可以另行
设计，试制。
□ Ordering information
1) It is suggested that the user should select the YCT series motor. The rated torque of which
should be larger than or equal to the load torque.
2) All the informations about the model, nominal power. Adjustable speed range. Whether the
controller required. Variety of tachogenerator. etc, must be clearly indicated in the contract.
For example: YCT160-4B, 3KW. 1250-125r/min, single-motor running without controller,
medium-frequency tachogenerator.
Another example: YCT250-4A, 18.5KW. 1320-132r/min, 4-motor running, pulse
tachogenerator.
3) Special types and specifications of YCT series motors can be designed and arranged in a
trial production upon negotiation.
