3 Phase Slip Ring Induction Motor

Be specially designed for energy saving purpose which is totally enclosed and fan-cooled type.

Good performance, such as high safety, energy saving, compact design, low noise, little vibration, high torque big breakaway torque, reliable operation, stable running and convenient maintenance.

Can be fit for common working environment and machinery without special requirement, such as pumps, fans, ventilators, mixer, crushers, food machines, agriculture machines etc.

Equipped with re-greasing system when the motor frame size is 160MM and above

Can be equipped with PTC if requested.

 

Labeling Standards

Series Code + Frame Size + Iron Core Length No. + Motor Poles

Example: YR2 160 L – 4

YR2—3 phase slip ring induction motor

160—the second part means the height of motor center (when the motor has no foot, it is same to motor with foot)

L—the third part means the base iron core length no.(S-Short Base, M-Medium Base, L-Long Base)

4—the forth part means the motor poles, this is a 4 poles motor, synchronous speed is 1500 r/min (50Hz); 1800 r/min (60Hz)

Ordering Informations

1. Please indicate the motor type, rated output, rated voltage, rated frequency, synchronous speed, Explosion proof Mark, mounting type, rotation direction(view from the shaft extension side)Use of the environment(indoor or outside)If the user havn't point out the rotation and environment, normailly we think is CW roration and used indoor.
2. When user have special requirments, For example: Dispose the stator, bearing explosion proof and bearing temperature sensors, space heater, Plateau use, specical frequency, mounting size change, special output, the user must, order can be confirm after signing the technical agreement with engneering department.
3. The catalogue is only fpr reference, and there may be variations.
4. This range of motor can also be made into Variable-Frequency motors, the range of frequency of which is 0-100HZ, the output and overall dimensions should be confirm separately.
