Hi there, i upgraded my battery from 48v 1000w to 52v 1500w battery and i assumed eventually it would blow and it has, so need a new controller to my 1000w voilamart hub. i did read you can put 2000w through that hub with no reliability issues and I've not even got to that. Just need to know what controller to plug in, i always have to solder the battery cables every time, don't mind a couple more if i know which ones to do and which controller matches? Thanks
My wheel only spins one direction with wires disatached from controller?

Is it a learning controller. These have a single wire that is connected to itself and marked "identirifcation" . You power up with wire connected. The wheel spins in either direction. If the direction chosen was correct, you break the connection and tape up the wires. The motor will have picked a algorithm to run the motor. If the wheel spun in the wrong direction during learning, repeat the power up til it spins properly.

For my thoughts on testing a BLDC motor's phase wires and hall sensors... see this thread.

Is it a geared hub motor?
When you have a phase wires shorted together there is lots of resistance turning the wheel. If you dont have phase wires shorted together there will still be some drag or resistance to turning but not too much.
Most Geared Hubs have a freewheeling one way bearing in them. So if its a geared motor then turning it one direction will be noticeable harder than the other direction which will have almost no drag at all.
If its shorted phase wires then it will be super hard to turn as in almost impossible to ride the bike.
Was there any catastrophic event like the axle spinning out of the bike and twisting up the wires? Did the bike fall on the wires and possibly cut them?

There's no shorts as I rewired the harness brand new as 1 cable was snapped below the thread. I think since jumpering the phase wires to see if the hall sensors inside the motor would be working, the bidet showed if there was a little jutter when spinning the wheel after jumper the cables it shows if they are OK inside or not
A geared hubmotor only spins one direction freely (so you can keep riding without power). The other has some resistance (but not a huge amount); so rolling the bike backwards is harder than forwards.
If the motor has shorted phase wires or windings, then it will still spin freely in one direction like always (easy to ride forward on the bike) but it will be VERY hard to turn the other way, perhaps impossible depending on wheelsize and personal strength (so rolling the bike backwards may not be possible; the wheel may simply skid).
If the motor suddenly stopped working and that is why you have disocnnected the controller, then it is probably shorted and causing this problem. That can be caused if you crashed or the bike fell over, and the wires were damaged at the cable exit from the axle. Or it could be overheating in wires or the motor itself, causing insulation to melt and allow phases to short.
If you've replaced the phase wires all the way from inside the hub to outside, then that leaves the windings themselves.
I'm not sure what you meant by "bidet"; if you clarify that it would help as I can't imagine a way to use one to test or troubleshoot this type of problem.
I would recommend giving us the complete story of how the bike behaved before the fault, *exactly* what happened immediately prior to the fault, and exactly what steps you have performed, in a list, for both troubleshooting and repairs. That way we will be better able to help you find the root cause.

This sounds like the same problem you have in this thread:

The two threads should be merged so that everyone helping you has all the information youv'e posted so far. I can do that for you.

So now your motor works normally?
If not, you need to post a *detailed* *complete* list of *exactly* what *specific* steps you have done, from the very beginning of this situation.
AFAICT This thread is also for the problem you have in this thread:

I ordered a new controller as othe blew up. Wired battery correctly wired 3 pin throttle correctly then what I done is rewired the hub and it was spinning freely both ways as it did prior to rewiring, I tested all different ways of the phase cables wired and messed with the 3 colours below hall sensors as the red and black are power and can't be rearranged. So where along the line its now locked from even trying to free spin disconnected from controller. Wich never happened till somewhere
