More than twice the weight of the D6 itself. Not sure what you would do with this? |
Hi,
A quick calculation of what you need to drive a 200hp electric motor.
200 Hp = approx 149 kW, The motor will no doubt have a Power Factor somewhere in the .8x% so I have used .85 as a median value.
This means you will need some 175 ekW to drive your motor at full power, your alternator ( the source of the AC Power) also has a limiting PF Value around the same as the motor so you are now looking at around 200kW Engine Power to get your 200 Hp motor power.
There are of course ways of improving the PF by using drive units etc but these all add weight and take up space plus of course there is that old nugget of........ the costs. And it is this last one that normally causes the greatest ructions.
