Hello Friends,
I am interesting in to know about the different and recommended Dynamomtric test availables for AC and DC electric motors.
Thanks for the Inputs.

RE: dynamometric testing for AC& DC electric motors
Dynamometric testing is different for a large variety of motors. One can also get many types of dynomometers such as hydraulic, electro-magnetic, frictional.
Please be more specific about the type of motor, its mountings, the type of cooling the motor usually needs and what you are hoping to achieve with the tests. Some people such as rewinders need to prove efficiency, others want to prove the load handling capability or over load conditions.

Specific needs are for prove efficiency at some loading conditions in a motor repair shop

RE: dynamometric testing for AC& DC electric motors
you wrote "Specific needs are for prove efficiency at some loading conditions in a motor repair shop". As you probably know there different standards for determination of efficiency mainly as IEC or IEEE, so should you follow these ones or simply the efficiency "input/output"?
If IEC 60034-2 should be followed, that is the simpliest one. IEEE 112 Method B requires more.
