Question for our electricians. I think the start winding of a motor has less resistance and larger wire then the run windings. Wonder if I am correct in that assumption...?? Lost the motor on my drill press, so I put on another, turned on the drill and the spindle ran backwards. Dumb me didn't even check the rotation before installing...!!! Made my day though........I had to sit down in a chair I was laughing so hard. All help on the question appreciated...!!
Tom

I just bought a 1/3 hp motor 2 weeks ago . Mine has a wiring diagram shown on the plate to wire it up in either direction Tom?? as to your question . I would guess more resistance would be needed if there was no capacitor? as the initial surge of electricity is higher to get the motor started .

Thanks for the comeback Ernie. Reversing the motor was job one today. Took the motor off the press, removed the cover from the circuit box , and of course a rats nest of wires. Picked what I thought were the start leads and reversed them. Motor just sat and hummed. One more try and it started in reverse. Started to put the cover plate back on and there on the inside was the wiring diagram stating the leads to switch. Another hi-lite day......................if at first it doesn't work read the instructions.
