How to select a suitable 3 phase induction motor for a compressor
(OP)
I need to calculate the capacity 0f a 3 phase induction motor that suitable for the compressor which gives maximum efficiency. The load of the compressor is 150kW. Now I want to know how we calculate the capacity of the motor that gives maximum efficiency

BTW, if you don't have data on your compressor and you have motors larger than the compressor, might as well couple your compressor with the motor and do a "measurement" of power input(1.732 x V x I x PF) for your compressor; as Archimedes suggests.

Burnt2x - I'm not sure I understand why you'd divide the required motor output power by the motor efficiency. The motor rating is the output power on the shaft. The input power to the motor includes the motor efficiency.
