Is this a volts converter ?

[Dale MacKay]

I need a little electrical help – I purchased a Boggs & Brown slip rolls, it has a GE 1 hp 3 phase motor~550 volts ~ below the motor is another GE box with transformers. There is a tag on the inside of the box is CR109B-DOAAP. I called a couple local electrical supply outlets but they didn’t have any listing for this GE box. Does anyone know this set up and if it changes just the volts or both phase and volts - I only have single phase in the shop, I didn’t want to blow anything up by putting power to it ;>) any thoughts on what I need to get the beast powered up?

Cheers

Hi Dale,

To me it looks like two circuit breaker relays that are used for changing the direction of rotation (back and forth)

Maybe if Tim Doty checks in, he can come up with "something better?" http://66.242.22.14/forum/images/icons/icon12.gif http://66.242.22.14/forum/images/icons/icon10.gif

Thanks Anders ~ that could very well be.

Dale, those look like the motor control relays to me. I have a 550V 3ph Doall bandsaw that came from Canada. I got a HUGE transformer from Boogiemanz John Brown to step it down to 240 3 phase.

em are reversing contactor, starter, it swaps two legs of the motors three phase wires to swap directions.

The transformer underneath is for lighting or controls. Not big enough to run a motor.

If ya was close by, I could make you a shopping list to make it work.. If the motor is not a multi-tap you will have to trade it out.. if'n it was a 240 tapp able motor you can make it work with a idler motor running in the floor..

I got details of that on another post..

You buyin the steaks? US'n electricians love steaks..

Post the frame size and details of the legend plate on the motor.. I'll look around, I got a mess of C-face motors laying about..

Steaks all around then – as long as no one is afraid of all the mad cow’s we have up here! I will look and see what the motor is. Thanks every one for the input I will keep you posted.
Cheers

Aussie sparky's love the Steaks too...could you make mine medium/rare???Yep looks like you got to change your motor. I probably got one laying around if you want to come down to get it.(pun intended):grin: :grin:

Didn't notice ya was a Canuck... I sent some welder diodes to a friend up there, the customs people charged him a new price for them.. WERE MEAN.. really mean to him.. Next items I sent "GIFT BOX checked".

HE thought I had sent them collect and he had already paid. He was wanting ahold of me till we figured it all out.

I got three 3phase motors running here, got a pair of inverters on the wall with twistlock plugs. Ya just plug it in and zoom.. get the most bang out of your inverter buck.

YOU need speed controls anyways.. I got a dc drive on my small one here. ROCK back and forth.. gives a whole new meaning to adding curve.

HE, by the way, sent me some hockey pucks.. really neat to planish on with a mallet.. I have two left.. I had never saw one before I got them outa the mail box.. the lil lady at the post office had to have one to show her husband.

THE model3 tube bender I got? Mike up there bought one, instead of the $300 I spent on mine he had to pay $1,000 and about four hundred per die set. If'n he is to buy anything else I am liable to sneak it up there welded to my lld truck..
We don't treat canadian products that mean. WE sure don't treat the chinese like that, you can see that at the harbor freight store.
