Vehicle - fix costs: low |
| |
|
|
|
|
At present, the price is difficult to predict but experts estimate that permanent magnet synchronous motor will be more expensive than asynchronous motor due to expensive rare earth magnets. However higher motor price will be roughly compensated by saved costs for gears. Some authors (cf. Koch et al. 2002) even assume lower overall investment costs through eliminated gears. This could be true if scale effects can be realised. |

Infrastructure - running costs: unchanged |

|
|
|
There might be an almost negligible increase in infrastructure costs due to increased wear and tear on track (unsprung mass!). |
