Hello, so I’ve been given a non operational Bionx PL350w direct drive hub and battery conversation kit bike and have pulled both the battery and motor apart to rewire the battery with a generic 13s 20a bms and wired up the motor with hall sensors and phase wires to work with a Brainpower controller. Success!!!
Back from the dead. Only issue is you can hear it from half a mile away. Very noisy! Sounds like the stator windings are rubbing on the magnets as is spins powered or freewheeling. Went so far as installing new bearings but no difference. Might stator aid or another form of lubricant help to quiet this down? Has anyone worked with these motors before original or hacked
 
If the rotor is contacting the stator, that's an indication that the hub bearings have failed.
