question on rewiring a HF bandsaw to 220v

[PARANOID56]

Hello, I recently bought a HF horizontal band saw (the one with coolant) and it says you can rewire it for 220v. i had an electrician come in and he had no idea how to do it. i usually can hook stuff up, but this made no sense.
Here’s the only diagram HF gives me.
anybody have any incite?

According to that diagram that motor is 110 only. Lead D being ground, A and B being hot and neutral. A 220 motor would have two load wires (hot) and 1 neutral with either a ground wire or the case acting as ground. Technically you could run it into a 220 outlet by only hooking up one positive leg but don't really see the point in that.

Thats not a very good diagram they gave. Sometimes there is more information on the motors themselves. Check out the name plates on the saw and pump. Also look under the covers of the terminal boxes sometimes there are diagrams. Its a typical Chinese set up in that they switch the nuetral not the hot lead.

Okay, looking at my compressor which is 220 or 110 you switch the nuetral for the second hot lead. 220v motors do not require nuetral the potential is between the two phases. BUT you also have to switch a jumper inside the terminal box in my motor to switch the windings over. Most motors are dual voltage compatible.

Are the wires in the motor connection box numbered? Is there mini-diagram inside the motor connection box?

A typical split-phase motor has 3 windings - each is 120V rated. So the trick is to put the two 'run' windings in series, and connect the 'start' winding in parallel with one of the run windings. The start winding has a higher resistance than the other two.

EDIT: Is the pump capable of 240V operation?

thanks for the help guys. lots of that info went over my head :D :D i like pictures.
so here are more
This is in the cap of the main motor. (was coverd by a cap, so i never saw it at first)

here are two pics of the wires coming out of the main motor.
three black wires come out of the motor, (two go to a cap) the other one goes to a braker
one red wire goes to the switch
one white wire goes to teh white from the wall
one yellow wire is also attached to the white from the wall

these are pics of the motor for the coolant pump. it does say it can run 220v.

and on the motor itself.

so, if i am reading those right the rings around the colors indicate the wirenuts. but, looking at the wiring, it seems the main motor is set up for 110v but the coolant pump is set up for 220v. is that corect?

For 220v operation on the motor, hook the red and grey lead together with a wire nut. I think the one in the picture that looks white is actually grey. Regardless of how it looks in the picture, the grey one is the lightest color one coming out of the motor itself. The black wire from the motor gets hooked in line (series) with the switch to turn it on/off. Run one leg of the 220v into the switch, and the other side goes to the black. The yellow wire coming out of the motor goes to the other 220v hot leg.

Basicly the same thing on the pump, I would guess they gave you an extra nut in the kit and you're supposed to use the middle post as a junction so you don't have to cut off terminal ends and use wire nuts. Take the red and grey and put them over that middle post with a nut to hold them together. The rest should be left as is, it looks like the switch is somewhere else compared to the motor pic.
