Answer / loboreliance2003

The motor drawing 1.6A on no load appears to be okay.The
motor drawing 4.8A on no load appears to have a fault. the
winding may be having not proper megger value. Or even
rewinding of this motor may have been done improperly. You
will not find this condition in new motors from original
manufacturer.

I have a shop heater with a 1/3 hp capacitor start, induction motor driving the fan. Intermittently, the fan motor speeds up significantly for several seconds (15-60 sec) then slows to normal operating speed. The manufacturer suggested changing the capacitor which made no sense, but I did it to no avail. Could this possibly be caused by the centrifugal switch intermittently reconnecting the start winding?
