Joe,

Direct drive of any kind should have close to zero maintenance needs - bearings are really the only thing that could wear without breaking. Inrunner or outrunner, low or high KV, should not make a difference.

Regards,

Dave

Does a low kV, direct-driven inrunner have the same maintenance issues as a geared inrunner (besides gear maintenance obviously)?
