Hey, for anyone who is interested I've solved it. On my controller I have a pair of wires called "Self Study". I connect these together with the power on and then disconnect them. Believe it or believe it not the wheels then turned in the correct direction. I'm not sure how this works but...

Hmmm. I don't know really. It is worth looking at to see if is possible. Thanks for your help.

Hi flecc. I tried that, with the phase leads but only one configuration works. As I understand it, one has to alter the phasing of the Hall leads to conform?? Is that correct?

I have just installed a new controller on my electric scooter and the wheel turns the wrong way. If I swap the supply leads around the wheel does not turn as the Hall detectors are not in the same rotation. Do I have to change both these sets of these leads? Why is a controller designed to...

Does anyone have experience/ knowledge of a typical lighting circuit on an electric scooter? While trying to connect up, to the switch side of the lighting circuit, a dc – dc converter to run extra lighting at 12V, I managed to short the supply, (ok I know I should have had the power off but I...

Well I eventually got around to completing this little task and it work a treat. Motor is running fine now. Thanks to everyone who participated with their help in this thread and I'm glad to hear it has helped others like Auldgit; well done.

Ok, thanks for that; we'll give it a try and report back.

Hi. Just been reading through this thread as a friend of mine has a very similar problem. He bust his twist grip and ordered a replacement. The replacement operates in reverse, i.e. at rest the motor is at full speed and when it is twisted fully round, the motor is at rest. The grip was returned...

Ok, thanks to both of you. I'll keep you informed.

Will do. They arrived this morning (brilliant service RS). It's not immediately obvious which way round they go. They are bevelled one side and a round spot on the other; any clues?

Ok, thanks. I've ordered three. As another member advised, it may well pay to change all three. Thank you for all your help.

Thanks for the helpful tips on how to change it; I’ll follow your advice. I'll ask the Spiratronics, supplier for a data sheet but for the sake of a few pounds I may as well just buy another and get the correct product. I’ve searched in the relevant places, like e-bay & RS, but it doesn’t come...

I had thought about that but I have read, elsewhere on this forum, that they don’t always run that well on a motor that is originally designed to run from a controller reliant on sensors, particularly at slow speeds. Also I am not sure how the speed control (twist grip) would interface with a...

I haven't removed the old one yet. I've, earlier, uploaded a picture of the sensors in the hub, shown via a link referred to, four posts back. You will see that the sensor will need digging out and there may not be much discernible left after doing so. You can, however, read part of the...

Ok, I know this is slow progress, I’ve determined that the “green” hall sensor is faulty and I’ve bought a replacement. Before I replace the old one I want to be sure I’ve got the right device. My understanding is that there are two types of sensors a digital position type and a magnetic field...

Faulty motor or controler I know this discussion was a long time ago but I have only just got around to stripping the motor down and investigating. There is no apparent physical damage to the sensors, ( I have uploaded a close up picture of them at this location...

>>The Hall sensors can often be dug out of the stator and replaced, fiddly but possible with care.<< Ok, Thanks. It looks like that's where I've got to start delving, intto the motor; I'll post back what I find.

I have converted a brushed motor, electric scooter to a brushless motor with suitable controller. Every thing worked fine for months until I overloaded the motor one day. The motor suddenly lost its torque and proceeded to run very rough; little power and very jerky. I assumed, at first that...

Sunrim Mammoth Fat rim, along with a Schwalbe Smartguard Marathon PLUS tyre. 26" Size: 47 -559 (26 x 1.75) The rim will need spokes; existing ones have had the hub cut out. These are the remnants from me canablising the hub motor and by all accounts are both of good quality. It seemed a...
