Standard, Current-Free Load Tests for Electric Motors

You will need to make yourself clear about what you want. e. g. What is a "free load test?"

I'm very clear regarding free load test, but i'm not clear how the percentage of free load test when the electric motor running.? I'm just want to know, where I can get the standard of free load test..can give me the reference...

I guess I didn't make myself clear . . .

What is a "free load test?" Do you mean, "What is the current in a motor with no (mechanical) load, and how does that compare to full load current?"

Are you looking for a design standard? Or are you looking for what the usual ratings are?

Design standards can be obtained from IEC or your local national body that publishes electrical standards. If you want to know what manufacturers normally provide, look at some websites and check the specs

I'm looking for usual ratings....

For my edifidication, would you please tell me what a "free load test" is?

OK, if you're looking for typical numbers, Google for 2 pole motors, etc, locate some manufacturers and read their specs. If you still can't find it, you will at least have the names and contact info for these companies, so call them up and ask for the "free load" currents, whatever that means. BTW, you still need to clarify that definition for us...
