You guys are making my post #3 look pretty weak!Yup. The elegant mechanical solution, easy to maintain and fix, far less chance of something going wrong. Dont reverse the motor, reverse the mechanism.
Pretty hard to do in a compact location like a drill press head. Plus on top of that 'V' belts do not take being crossed over and ran at high speed well at all. Given the tight location and small diameter pulleys keeping the belt on would be difficult plus frictional wear would be very high.Get a longer belt and do a cross/over.
I thought it was pretty easy to figure out by the pictures. There are only four wires and it's obvious where they goTo hard to diagnose from a picture !
Won't do any good on a single phase motor.Or, you may try a VFD.......
The problem is he is usually to lazy to learn also!find the laziest son of a gun you can, give the problem to him and he will find an easy way to solve it. Gotta listen to the lazy folks more.
As stated above. Not enough space inside top.The startup winding would most likely have the starter cap on it.
The motor is driving a pulley, yes? Why not put another pulley or gear in line with the drill mechanism that reverses the drill mechanism rather than futzing with the motor?
That's what I'm doing if my motor ever dies. 3ph motors are dime a dozen.Or, you may try a VFD.......
You can see the splices in pictures. (I believe)It is possible, I did it on several 230V 1/2 Hp GE motors. On some just brought out start winding leads for reversing switches. The other end of the start winding may appear to be burried, but it is on the surface as a little lump laced up.
As per post #14 just 4 connections, 2 windings for a two pole motor.I would also like to experiment running a cap start motor on vfd.
It might work on a small duty cycle application, if it can be balanced to prevent fault trip.
It's usually impossible to move the field windings. If you've ever cut the case off one of these motors for scrap metal, you would see the case pop open like it has been under pressure all its life. You simply can't scoot the field around inside the case. If you could, reversing the motor would be a cinch.Sounds like #12's idea in post 3.
Will the field windings come out for reversal?
Bernard, now this seems some what logical. Do I have to go digging around in the windings to accomplish this? Trying to get better photos of whats going on with the wiresIt is possible, I did it on several 230V 1/2 Hp GE motors. On some just brought out start winding leads for reversing switches. The other end of the start winding may appear to be burried, but it is on the surface as a little lump laced up.
I rather like the image of the shaft sticking out the other end.....You guys are making my post #3 look pretty weak!
