Score! I stopped by an estate sale yesterday at one of the local fly in communities.. Now I have to figure out how to get it off the trailer! |

Is that a single or three phase motor? |

Ray it is a 3 phase motor, I need to find some way to convert to 3 phase. A rotary converter is way too expensive, I have read mixed reviews about static converters. I may have to go with a VFD. Not sure yet. any suggestions? |

Bi-directional hi/lo spindle speed like a bridgeport? If so then probably all you need is a 300 uf 350 volt or better ac motor starting capacitor with a momentary "start" pushbutton. I built myself a rotary from a 3hp scrapped motor from work. Added a motor starter and momentary contact for the start capacitor. It runs my Monarch lathe and Bridgeport/Alliant mill. I'll have to look ....I may have enough stuff to throw another together. |

Bought the new one phase motor cheaper than the cheapest phase converter. A little wiring to do but nothing complex....well....a cutter has lots of functions with the relays but it wasn't that big of a deal. |

3 phase converters are pretty easy to make, just find ya a good 5 h.p. 220 3 phase motor. then a small 110 motor to start it with and a big power switch. spin up the 220 motor with the 110. the 110 motor was connected to the 220 converter motor shaft to shaft. I used a rubber hose and hose clamps. 2 legs of your single phase 220 go to the 220 converter motor then all 3 wires out of the converter motor go to the mill. I had a switch to the 110 starter motor it spun over the 220 converter motor, had a big 220 switch that once the start motor was up to speed, we would throw to a big power switch to the 220 converter motor, once up to speed we would turn off the 110 motor and it would keep on running the 220 converter motor. hope that helps some. |

It is a standard bridgeport type M head with forward and reverse. 1/2 hp. The speed is controlled by changing the belt up or down the pulleys. |

Here is a thought: 1/2 HP 120V and 240V reversible motors are readily available... the problem would be mounting it. Might take some fiddling with the wiring to get the reversing to work. |

Might take some fiddling with the wiring to get the reversing to work. Single phased motors have to coast to almost a complete stop before they will reverse or they will continue to run in the direction they were. You could try what animal did with a smaller motor. You'd have to fabricate a mount and have a reversible motor to spin her the other way. but after all that a new 1/2 hp reversible motor would be less trouble. The one thing you would lose would be able to instantly reverse it when tapping threads unless you have one of those mechanical ones.

If you go with a VFD you'll need to go with a motor rated for it especially at slower speeds. At slower speeds the motors run hot!!!! I'll try to check the scrap heap this week to see what I can find. Probably be Wednesday when I have a little free time. |

Why don't you just buy a STATIC phase converter of about a $115.00 Heres a link to Enco where I buy some things from.. http://www.use-enco.com/CGI/INSRIT?PMAK ... TPG=INLMK3 |

I am looking at my options, I have been reading at some machinist forums, right now a VFD looks better than a static converter. The rotary converters cost more than I paid for the mill! I'll come up with something probably after Bensen days. |

Single phase motor.

Gabor, it is not that easy, the motor has the mounting lugs cast into the housing, plus the extra long shaft for the stacked pulley, not a standard motor at all. |

Can you find the data plate and see what frame it is or does it even list a frame size? From the looks of it it is a OEM made specifically for that mill. I checked the stash and all the vfds available are 3phase/3phrase. Someone found the 2 single phase/3 phase ones and adopted them. The only single phase to 3 phase inverters left are the old HR2000 drives and I doubt they will let me have a motor since they are still in use plus the motors and drive require the encoder ( more wiring) I will ask. they are 1 hp and up. They are c-face mount so an adapter plate would have to be fabricated. You wouldn't need stepped pulleys. You would have to move the driven pulley up to align with the motor pulley. I may have time to look in the scrap yard Monday if they leave me alone. |
