standard motor sizes kw

Motors from 0.37kW to 375kW make up the vast majority (approximately 90%) of installed motor population and are covered by the standard IS 12615:2011. This fulfills the need of the manufacturers to design motor for a global market. This standard defines four efficiency classes for nominal frequency 50Hz.

Motors that fall witin the EI1 efficiency class have the following specifications: Output is 0.75kW to 355kW. Poles are 2, 4, 6, 8, 10 and 12. Speed range is from 500rpm to 3600rpm. RPM frequency is 50Hz or 60Hz. Temperature class is B class. Insulation class is class F. Protection technology used is IP55, IP56, IP65, IP66. IE2 - High Efficiency

0.75 - 375 kW shall have a minimum efficiency class of IE3, Motors with frame size from 355 have feet integrated with the motor housing.

From 1 July motors between 0.75 kW and 1000 kW will be required to meet a minimum efficiency class of IE3, the group of smaller motors from 0.12 kW to 0.75 kW minimum IE2. From 1 July 2023, motors between 75 kW and 200 kW will be required to meet the even higher efficiency class of IE4. All the details are available here.

In frame number 145, for example, the first two digits divided by the constant 4 is equal to the “D” dimension, 14 divided by 4 = 3½”. Similarly, the “D” dimension of a 213 frame motor is 5¼”, 21 divided by 4 = 5¼”. By NEMA definition, two—digit frame numbers are fractional frames even though 1 HP or larger motors may be built in them.
