Products Induction

EMA Series Cast of Iron Three Phase Induction Motor is specially designed for European

market, whose terminal box is located on the top of motor.

EMA motor is totally enclosed and fan-cooling designed. They are newly designed in conformity

with the relevant requirements / rules of IEC&DIN42673 standards.

EMA 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.  Fixing measurement and power grade completely conform

to IEC standards.

EMA series three phase asynchronous electric motors are widely used in many fields, such as

machine tools, pumps, fans, transport machinery, mixer, agriculture machinery, food

machines, agitator, air compressor etc. We also can supply aluminum housing type for frame

size under the standard of IEC132.

For the Connection Model of EMA motor, please refer to the Name Plate on the motor (The Y

Connection is adopted by motors′Output equal or below 3kW; The Delta-Connection is

adopted by motors′Output above 4kW).

EMA 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: EMA 90 L - 2

EMA—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)
