You may want to check the cost of winding wire, sleeving, insulation paper (letheroid and milinex) and varnish etc., before making the decision to go ahead. Baking can always be done with some high wattage bulbs. Never put it in an oven as the varnish can catch fire! Can you post pictures of the name plate and the interior of the motor? |

I've priced the rewinding cost and the price of materials is 1/4 the price of a rewind. The motor is an partially open style motor with a cover that attaches to the rear of the motor on 3 of the 4 studs; this rules out TEFC motors. It's also foot mounted which makes it even rarer. |

Have you Googled “36 slot 4 pole 3 phase winding diagram” ? Rewind cost is virtually all labor. The only time rewind makes sense is when you have a non-standard frame or some wacky high pole count, oddball shafts or strange mounting arrangements. There is a reason for a shop to quote a high rewind price: they’d really rather not do it. Here in the US, it has gotten to the point where 20HP and higher is the current cost decision point for rewind or replace. I doubt it’s much different in the UK. Don’t overlook the fact that motors like yours are so cost engineered that the wire may not be a standard gauge. You get close and then find you cannot get the required number of turns into the slots or you break turns trying. Yes, it does look easier than it actually is, especially the first five or ten times. Given you’ve never rewound a motor before and without the winding forms, tools and proper materials, don’t expect it to work long term. Sure, it can be done but IMO, it’s a fools errand when it’s a bog standard piece of kit. New, open drip proof, foot mount 4 pole should about £50 new, maybe £100 worst case for a name brand. Unless the materials fall out of the sky for free and you don’t value your time whatsoever, I cannot imagine a case where it makes sense to learn how to rewind a motor, especially starting on a 56 frame. Just cleaning out the slots will be a real chore. |

Can we gets pics of the motor and mounting arrangement? Making a modern standard motor fit is likely the path of least resistance here by an order of magnitude, V belt (I'm assuming) drives aren't picky about alignment. |
