Solved: What voltage to Bench Test Mavic Pro motors? ANSWER You need an ESC

kartane · Mar 22, 2019

What voltage do I need to bench test a Mavic Pro motor? Are Platinum batteries the same? I have a drowned MPP and I would like to know if the motors still work.

Do I have to desolder them from the circuit board? I could not find the motor specs anywhere. Yes, I am aware they are variable speed. I just want to put 2 wires across a motor and see it work.

Thanks for looking.

These are not D.C. motors. You will break them if they are not already broken.

– I should clarify that - it needs an ESC to power it - you can't just hook it up to a battery.

Really, so the circuitry must include a transformer.

No - see my clarification above. I realized after posting that it looked like I was implying an A.C. motor. It's a 3-phase DC brushless but you can't just feed it a simple D.C. voltage.

That makes sense. It needs to be variable.

OK, thanks for the information. Simple question with a complex answer.

For testing brushless motors there are corresponding devices from the RC sector. For example, you need such a device:

SkyRC BMA-01 Brushless Motor Analyzer / Tester

But why do you want to test a single motor, is it a spare part? You can also do a simple test directly at the MPP. Start the engines without mounted propellers, and do a listening test. If all four motors are running and sound the same, then it can be assumed that they are working properly ...
