Products Induction
Y series three phase asynchronous electric motor is a kind of low-voltage squirrel cage 3-phase induction motor. They are totally enclosed, fan-cooling newly designed and to be in conformity with the relevant requirements & rules of JB/T10391-2002 & IEC standards.
Y motor have the advantage of high efficiency, long working life, energy saving, high starting torque, low noise, small vibration, big breakaway torque, reliable operation performance, easy & convenient maintenance.
Y motor are widely used in many fields, such as machine tools, pumps, fans, transport machinery, mixer, agriculture machinery, food machines, agitator, air compressor etc. However, Y series three phase asynchronous electric motors are unsuited to be used in that place where combustible, explosive or corrosive gas exist and other special requirements forbidden.
For the Connection Model of Y motor, please refer to the Nameplate on the motor. (The Y Connection is adopted by motors' Output equal or below 3 KW; The Delta-Connection is adopted by motors' Output above 4 KW).
Y Motor can be equipped with PTC.
For motor of frame size 160MM and above can be equipped with re-greasing system.

Products Standard
Motor product labeling confirms to the following rules: Series Code + Frame Size + Iron Core Length No. + Motor Poles
Example: Y 90 L - 2
Y—means induction motor
90—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)
2—the forth part means the motor poles, this is a 2 poles motor, synchronous speed is 3000 r/min (50Hz); 3600 r/min (60Hz)
