Magnetische Zahnräder

Comparison of mechanical gears and magnetic gears

Pros of mechanical gear	VS	Pros of magnetic gear
1. High very high torque/mass (specific torque)		1. Non-contact
2. High very high efficiency		1.1No lubrication
3. Mature technology		1.2Low maintenance
		2. Easily integrated in electric machines
		3. Potentially low vibration
Cons of mechanical gear	VS	Cons of magnetic gear
1. Contact-related wear failure		1. Unknown limits on specific torque efficiency
1.1.Requires lubrication system(s)		2. Magnet temperature limit
1.2Routine costly maintenance		3. Individual magnet interaction weaker than 1 gear tooth pair
2. Strong tonal vibration cabin noise
