Hey I have a BLDC square wave controller. How to check the efficiency of the controller alone (not including the BLDC motor). Any suggestions ?
I have checked with DC load test machine, but what I get was the efficiency of both motor and controller. But I want to efficiency of the controller only.
Are two wattmeters suitable for this, which are designed for 3 phase power measurement?
I think a power analyzer could be used but it is very costly and even we don't have one.
Advance thanks guys...
