(Also you can force air cool and do some other stuff. A Kostov 11" Alpha ($2700) is rated for 50kw continuous and puts out MONSTER torque compared to a BLDC. BLDCs do NOT overload well)
1) cost ... Well, lets just look at the numbers shall we? How about a cost comparison?
Using the Kostov 11 you say is $2700, add $3150 for a Solitron 1, add $130-200 for a contactor, How much for 4 10amp 12v circuits? Lets pretend that is only $100. So you are OVER $6000!!
plus, you had to house and wire the contactors and auxiliary power circuits and pay shipping on all the individual components. hmmm..
OR, you could spec the Scott Drive for only $5495. It has all that stuff on the inside. Did you realize that is the price WITH the motor?
2) not sure what you are saying here. Please elaborate.
3) Cost per unit of performance is LOWER for BLDC than any other motor type. Maybe it is just because I live in MT and we have to cross very steep and long passes, but a high continuous hp is the ONLY thing that will allow you to do this. Otherwise you will be on the side of the road with the VW busses... Overheated and broke down
If you google Neodymium you will find this "rare" earth material is actually extremely common and easily produced. Not a problem at all.
Sorry- forgot to talk about "monster" torque.
The Powertec E215 is 211 lbs and puts out 500 ft lbs. Not sure what you mean by "monster", but that doesn't seem all that shabby.
