Looking for the best solution provider to measure the efficiency of electric motors. Anyone willing to share his experience?

COME, . . come, . . you are not expecting to receive many valuable comments on your "one-liner", are you?

You are likely to get as much advice as the effort you put in into the question itself.

What size?

AC, DC, Voltage range, etc.

For integral HP solutions I still prefer a dynamometer and accurate electrical instrumentation.

A DC machine for the dyno load is easy to control.

Our dyno motor was mounted in bearings and had a torque arm to load cells.

In my opinion, a dynamo-brake dynamo-meter is the best, although its design is of old times.

I have used it to evaluate a new design automotive motor-alternator I am developing.

Good luck,

Arturo

Try the manufacturers. They publish lots of technical data about their motors. A few telephone calls should do it.
