how do you run capacitor start ac motor in reverse
I have a couple of shop projects where I need to reverse a 110v capacitor start ac motor .. whats the simplist way to do this .. tia mike |

how do you run capacitor start ac motor in reverse
If the wiring is accessible to reverse the motor, there should be a diagram
on the motor or inside the splice box to show you which wires to switch "Mike_in_SD" wrote in message ... I have a couple of shop projects where I need to reverse a 110v capacitor start ac motor .. whats the simplist way to do this .. tia mike |

Just use the other end. Unfortunately thats seldom an option. no .. its on my drill press Use left-handed drill bits. People should always say why they are asking a question. |

I dont know .. it was a pretty simple question. I am a shop nut working on my shop more than on projects. There are potentionally lots of hacks to my equipment that could benifit from this knowledge. I guess if you dont know the answer, you can always be funny. or not |

Actually LH drill bits wouldn't work. My mistake.
But I think the rest of my last post was still on target, since I think your reply was based on your idea that they don't exist.

no .. its on my drill press Use left-handed drill bits. People should always say why they are asking a question. Sorry mm, you dont get to make the rules. Its like guys that cry about top posting (which you did) I can see their argument .. but .. I can give you a counter argument that is just as valid. So sometime I top post and sometimes I bottom post. What you are doing by wanting to know WHY .. is trying to decide if I actually NEED to reverse this motor. Think about that .. slightly insulting in itself. And as you can see by your attempt at an answer .. the only thing that will work is ... reversing the motor thanks to the guys that actually answered my question. Mike |

I did this when I was a kid, which is getting to be a long time ago. IIRC, you have to reverse the relative phase of the start and run windings. My recollection is that I used a 4PDT switch; but, thinking about it now, it's not clear why. It seems like you could just leave one winding unswitched, and use a DPDT to reverse the other. Maybe I was using it for an on/off switch, too? Maybe my mind is gone. George I know I have used 4pdt relays on dc motors, kind of like a mechanical H bridge ... for some robot platforms I have build but .. not sure how to apply here. somebody suggested that if I take the plate off where the main ac comes in that, there should be a diagram there to describe reverse operation. I think that may be my best bet. thanks for the reply mike |

These may help http://www.metalwebnews.com/howto/el.../elec-mtr.html Look at the last couple pages here http://www.hubbell-icd.com/icd/drum/...ontrollers.pdf For the reversing function a 4-way switch - as used in lighting circuits - could be used. Start winding to one pair of terminals, connection to rest of motor to the other pair of terminals (or whichever pair of wires shown in the motor diagram). A 4-way switch gives you straight through in one position and crossed-through in the other position. bud-- |
