Magnetic gears
Magnetic gears are non-contact power transmission mechanisms making use of the attraction and repulsion properties of the magnets.

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 |
