Burnt out my windings, looking for a replacement stator or whole motor if its cheap

I really want this but am in Europe.

If you can be bothered to ship I'll pay.

You wind it like this, it's going to take 420 metres of 0.5mm enamelled copper wire which will cost me £10 plus maybe several hours, of which I have plenty at the moment. Worth a try considering the motors are toast otherwise.

Thanks but I'm going to change the motor and am trying to work out what might be the best option.

"But here is why I think it works for me. The low speed motor simply tolerates the slower speeds you get when you climb steep stuff. So the same 1500 watts or so I can get out of that motor can be used at slower speeds. It's not more power, or more torque. It's just less stalling of the motor when ...

A 5T motor has more torque and less speed than a 3T motor, the number of turns affects the RPM per volt so you can rewind a motor with more turns to get more torque and less speed at the same voltage. Prove me wrong here if you like, I see you are a very experienced user of the forum. Tell me what I...

If I was going to use a Bafang I'd just put it on a decent mountain bike frame instead of this cromo steel lump with 80s suspension design. Have been handed a dead MXUS which I am going to try and rewind for torque rather than speed. That could be quite a lot of fun if it works. Im talking to someon...

Ah right, thought it was like the one in my Raptor, didn't follow the link.

My Sabvoton is unlocked for 200A so a 63A domestic breaker fits the bill nicely.

LOL. Charming.

I haven't done it before so I don't know what I need to know and was just asking for some help...

Nice work. The 63A breaker is rated for use at 240v, so its more like 200A for a 72v pack.

I am going to do the rewind, so I'm looking for tips to do it properly, not naysayers telling me not to bother. You haven't seen the inside of either motor. There is only damage to one of the phases so its more likely a malfunction than overuse. If I get them working its a bonus if I don't I have le...

I have never ridden a geared motor, how does performance compare to MXUS 3k, and which controller did you use with it?

Seems my Sabvoton and maybe Adaptto isn't going to work.

Having taken a closer look it’s not going to be feasible to recoat the wiring so a rewind is my best bet. Have looked into it and it’s really not all that complicated. A couple hours work to save hundreds of dollars on a new wheel seems like a good payoff to me. There’s 750g of 0.5mm copper wire in ...

There are a couple of hub motors around here that have been run too hot and then left to stand resulting in blackening of the windings in one particular area. One is an MXUS 3k and another is a similar clone. Needless to say they don't work any more due to current leakage between the wires.. Is the ...

Someone has suggested a MAC 12T motor which has high torque and should give good speed at 84v.

Can anyone comment on how the power may compare to an MXUS 3K?

Interested, how did they perform in the Nyx? I'm looking for a rear wheel for my Q76 that doesn't weigh 15kg+, I have an 84v battery and a Sabvoton 72150 (until my Adaptto gets fixed). I assume that they will fit in a Raptor with 155mm dropouts. Singlespeed or cassette version?

Thanks Tom, Something is definitely amiss then. It's got a Shinko trials tyre on a 19" Holmes rim so the weight is going to be about the same as yours, and the rear brake is Shimano Saint with XTR lever, a common mod that once used by downhill racers to get more power than any stock lever/caliper co...

No you don't understand. The back wheel weighs 19kg, Thats almost 50% of the bike and is causing problems with traction and manouvreability - the rear wheel has so much rotating mass that the brake can't lock the tyre making it very hard to ride offroad. Instead of rolling over things the back wheel...

But the real reason I replied is to ask you about the Multistar. How does your pack deal w/ the high discharge rate. The multistars can dump insane amounts of amps, thats why people use them. I made very similar build on Q76 with exact same Multistar setup than you and Sabvoton 72150, Cycle analyst...

Looking for hub body for Cromotor v2 or 3 (the bit with the magnets) plus side covers if the bearings are still OK.

Thanks!

Yeah I’m interested,

Have you made any modifications to the frame?

Great, I was sold a lemon by the looks of it. Was told I was getting a stunning deal, got it home to find most of the parts pretty heavily worn, rust inside the frame and then the controller fails after one ride. Of course the seller wasn't interested in hearing about any of the problems, when I que...

I'd say you have shorted phases... the reason why it blew the MOSFETS blew in the first place. I'd be checking your motor. Yeah I though that could have been a possibility too, but this happened halfway through a charge while the bike was stationary and the motor works fine with a Sabvoton. If the ...
