typically in their eyes ( panasonic) the charging \ cleaning station is so cheap theyre not going to offer replacement motors for this kinda thing.
odds are youll have to dig around the google machine and see if anyone else has done this repair on the side and hope they listed the motor. ill search around and update if i find anything
if no luck there then youll have to get measurements of the motor physically and then some how figure out the motor speed and required voltage \ amperage.
