motor troubleshooting question.
air compressor, 1ph/208v motor.
running current is 23.8 working under load. 5.3kw. 7.5 hp TEFC
starting is another thing......
stutters badly for five or six seconds, then lights up
and runs smoothly.
i'm guessing the centrifical switch has either stuck
open, or closed. if stuck open, there is no starting
if stuck closed, it burnt out the starting cap.
i usually just remove and take to a motor shop.
is there a way i can easily test the centrifical switch?
or, does it sound like something else entirely?
it was working fine, until they moved it about 7'
further down the wall. same circuit, same feeders,
same everything. now, it's like trying to kick start
a harley with one plug wire disconnected.
motor's been in service a year and a half.
