Hi All,

Does anybody on here have the experience of replacing a damaged wiring harness from a direct drive brushless rear hub motor? Is it as simple as just removing the motor cover and cutting back the wires as close as possible or do you need that special case clamping tool that separates the whole magnet from the motor casing in order to get to the wires, any good tips??? Cheers!

MS.

Hi ms, you lost me a bit there but it's been a long old day

What motor is it exactly, photos always help

Brushless usually just have two wires or am I missing something

Has wire broken or stripped inside the casing? Is that the main issue? Motor innards access ?

Wrong end of the stick Kirstin you must be tired :(.

Brushed motor 2 wire, brushless unsensored 3 and sensored 8/9.
You don't say where the wires are damaged.
Even if you get the hub open the issue will be to get a new cable through the hollow axle and then soldering in place the individual wires. Unbinding the motor windings and then binding them up again.

Yes. It's pretty straight forward because there's plenty of room to fet at everything. It's a different matter with a geared motor because the whole motor needs to be disassembled, then it's really difficult to get the wire through.

The most difficult thing woth a DD motor is pulling the rotor from the stator. The magnets are very strong. I did it by standing on the wheel so that the axle gets pushed through.

Nice one again d8veh, so its just a matter of removing the screws and taking off the plate cover to access the internal wiring ?

Yes. It's just the physical effort of separating the two halves that's difficult. Remove all rge screws in the side-plate. Remove all nuts, etc from the axle, then stand on the rim to push the axle through the sideplate. It might help to have something/someone to hold on to to keep your balance.

Ok then, I thought it was just removing the cover that's all, ive got a better picture now.
Laters!

You might be able to do it by just removing the side-plate from the side with the wires coming out.
