A motor is required for an industrial air extraction system. The fan speed should be constant between 0 rpm and 2900 rpm, say two speeds. The maximum torque to nominal torque ratio should be no more than 4.0, the torque rating should be at around 100 Nm. The power factor should not be lower than 0.8 for power factor correction reasons. A 100A miniature circuit breaker (MCB) will be used to protect the motor. The enclosure should meet IP55 standard, and the feet are to be bolted to the stator and made of cast iron. From the ABB motors data sheet link attached select a suitable motor, giving the motor type number.

Efficiency values are given according to IEC 60034-2-1; 2007.
Please note that the values are not comparable without knowing the testing method.
ABB has calculated the efficiency values according to indirect method, stray load losses (additional losses) determined from measuring.
