Hub motor running in reverse

[Paul T]

I installed a front hub motor, connected the three faze wires, the hall sensor wires and the throttle when I hooked up the battery it ran in reverse I fitted it as per instructions from the website, its a PaPa motor, I did nothing wrong. Does a hub motor run just as well in either direction? would reversing the three faze wires then run it forward? or is it better to turn the wheel around in the forks which is more of a hassle as I have fitted two torque arms. Thanks

I've come across a few Ebay controllers that have a "self learning" jumper, it actually controls which way the motor spins. My controller was sent to me making my X5404 and GM DD hub both spin backwards, Found out I had to set the jumper, unplug the battery pack then unplug the jumper again for it to make the motors spin in the correct direction.

Whats the jumper? which plug is it? thanks 8)

Front motor, if it has no disk brake, flip the motor.

If you need to reverse it, try a different wires order, Like swapping blue and green or whatever. There will be a wire order that runs good forward.

If no disk though, just flip the wheel. You have a good running wire order, and you could find another that is not good, and end up with a damaged controller.

Oh really? I can just swap wires? that would be so much easier than flipping the wheel as Ive fitted two torque arms and zip tied all the cables neatly etc. Its just odd that its not running forward wired up correctly with colors corresponding, but damaging the controller is a worry. I did try it with a battery that wasn't supplied with the kit, I'm still waiting on that to be delivered but that shouldn't matter hey? I used the same voltage 48v, just different Amp hours 10 and 15.

Best to flip the wheel if your not using disc brakes. Swapping wires requires the correct combinations of the 3 larger phase wires an well as the correct combination on the smaller hall wires.

I doesn't matter which battery that you use. They all require positive to the controller red wire. Wiring the controller red to black will result in damage to the controller.

Copy and save the chart in this thread for finding Phase/Hall combinations:

If you don't have hall wires, it's much less complicated. All you have to do is swap any pair of phase wires.

That's true. I just assumed it was a 7 wire motor. If only 3 fat wires, swap any two for reverse.

If you have 7 wires, swap any two fat wires, then have fun finding the right combination of the other three small wires. Red and Black on the small wires stay the same.

the real way to make your motor run in reverse is

so you have 3 bigger wires in 3 different colors blue green and yellow
and you have 6 smaller wires in one connection
in the 3 bigger wires you need to connect the blue to the yellow and the yellow to the blue
in the smaller wires you need to connect the yellow to the green and the green to the yellow

That only works for certain with your specific combination of controller and motor, whatever those happen to be.

If the motor has a different internal wiring order, or the controller does, then a different set of wire swaps would be needed.

Unfortunately there is no standard wiring order for halls or phases within either motors or controllers. If there was, then every controller and every motor using that standard wiring order would connect to each other with the same phase/hall order...but this is not the case, as there isn't such a standard order. Even the same controller (or motor) from the same manufacturer may have a different connection order to the wires inside it, from batch to batch, though this is less common, thankfully.

Some controllers (and motors) even use all the same color wires in them, so you can't even go by color.

Worked great on pexmor 1200 watt
