|
|
The wheel-mounted permanent magnet synchronous motor is an interesting alternative to conventional AC asynchronous motors with gear transmission. In a wheel-mounted construction the torque of the motor is directly transmitted to the wheel.

Wheel mounted permanent magnet synchronous drives are an attractive option for future vehicle layout since they offer further increase in power density and overall traction efficiency. Principal technological or economic barriers do not exist or seem solvable in mid-term. Permanent magnet synchronous technology is more mature at present than transversal flux technology which is also discussed for a wheel-mounted drive. |
