YCT Series Electromagnetic Adjustable Speed Motor

Description

YCT series electromagnetic adjustable speed electric motor is one of the derived series from Y series asynchronous motor, which is designed under the organization of the Ministry of Mechanical & Electronic Industries of the PRC The electromagnetic adjustable speed motor is composed of three parts, i.e. 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 regulated 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.

a. Free of out-of-control zone;

b. Wide adjustable speed range and stable speed adjustment;

c. With sped negative 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.

Applications

The YCT series electromagnetic adjustable speed motor can be used in painting lines, transmission belts of assembly lines, plastic injecting machines, dyeing machines, printing machines, pumps, blowers rotary furnaces, wire drawing machines, calendars, air-conditioning equipment, transfer equipment, etc.

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 information about the model, nominal power, adjustable speed range, whether the controller required variety of tachgenerator. 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.
