- Paul,
-
- I had a similar problem with the motor on my 1 year-old Delta
- Contractor's saw. It turned out that the switch that removes the
- capacitors from the armature, once the motor gets to operating speed,
- had some crud in it. The crud prevented the switch from closing
- (capacitors in the circuit), so there wasn't the phase offset necessary
- to start the motor. The end result was the motor turned at a very low
- RPM, made a loud humming noise and tripped a 20 amp breaker (110v) in a
- matter of seconds.
-
- I took it the motor housing apart, cleaned out the contacts,
- reassembled, and bingo, worked great.
