Default Testing a pm dc motor

Now you can wind a bit of string round the shaft and pull it to see if it
generates any DC output! Of course if there's another motor you can link
it
to with a bit of hose or similar (as a flexible coupling; no water!), so
much


the better.

Mike.


Will check or DC output.

Ah, now that you mention it, this equipment experienced a flood which
probably submerged the motor fully for 48 hours (late last year). Not
operated when submerged (!) but probably some moisture still in it when
first
operated after the flood. (2 other equipment suffered damage: a VFD and a
contactor burnt out.)

Thanks.


That is something that should have been noted up front. You have a bad
motor.
