Hey folks,
So a few years ago, I bought a SkateMaster UK-branded board and modified it to use li-po batteries instead of SLAs. It actually worked pretty well, but I got relatively little use out of it before, during a trip to work in 2017, it stopped working and smoke started escaping the motor. I haven't touched it much since. The manufacturer had gone under before I even bought the board, so spare parts don't exist.
I took the motor apart and the permanent magnets seem to have flaked quite a lot - there's lots of metal shavings in the motor casing. However, the rotor seems to be in good condition - the windings don't show any evidence of burning or melting, and there's still electrical continuity. As I'm guessing is a common design, the motor housing that mounts to the rear truck is the casing itself, with the magnets attached, so there's no real option to mount a replacement motor in the same housing.
Now with COVID giving me plenty of time at home, I've taken another look at it. I'm tempted to clean up the metal shavings, reassemble the motor and try it - in theory, I can't make it any worse, although there's nothing to stop this happening again. As I've spent rather a lot of money on the li-po kit, I'd like to salvage it rather than replacing the whole board.
If I can't salvage the motor myself, what are my options? The motor is 24V/350W, but some casual eBaying hasn't turned up much in that power range that would be mount-able on a skateboard; there's also a third wire to the motor which I assume is some sort of RPM sensor for the ESC, which these motors don't have. There's plenty of skateboard motor listings, but I'm struggling the read the ratings in KV. And of course, there's the mounting issue - it doesn't have to look perfect, but it does need to be reliable, seeing as how the motor on a skateboard is both power and brakes so the last thing I want is the motor coming loose!
I heard that motors can be refurbished by specialists when my car starter motor had issues (turned out to be unrelated to the actual motor), but I'm unsure if it's cost-effective to try this approach.
Any suggestions?
