In mechanical gear systems, dust,
noise, vibration, and tooth wear are generated by frictions among gear teeth,
and suppressing friction requires lubrication. Magnetic gears transmit torque
by magnetic forces without contact and so avoid contact-related problems. The
present paper discusses magnet arrangements and the shape of stationary gear
teeth to improve transmission torque in surface magnet type magnetic gear
transmission mechanisms.
