EV2Go's - Lithium Powered Trike

I just read your tread and it is very interesting reading. 7 months ago I started building a trike with a Harley Davidson frame and a 11kw 230/400V ac motor and Omron 18,5kw vfd. I had the same problems as you deciding which rear end to go for. First I had my mind set for a Frakenstein rear end, lik...

Twin AC engine

Thank you for a fast reply.. I live in Norway and i got the controllers from work. Someone connected them to 400AC and they are ment for 240VAC. So the input are damaged. I belive it is possible to replace the varistors and they will be fine, but I will use the DC bus and the engine output, maybe it...

Twin AC engine

Hi Hebbe, could you wire these motors in delta for a lower voltgae? or is the 240v already in delta? you could put a capacitor in series with the traction pack for a higher DC bus voltage. it would have to be one large cap though. how much of an increase in power were you thinking? Matt I have't ch...

The motors are 3-phase 240V

I was planning on running the dc-bus on 350VDC.

Is it possible to use capasitor to boost the voltage for a little moment? Just as a NOS button on the gear leaver?

Twin AC engine

I have two Yaskawa E7 240V 18,5kW drives that i like to use with a 11-18,5kW AC engine. I have not found a donor vehicle, but I would like a pick-up or a van. I have looked at a VW Transporter with rear engine. This vehicle has rear wheel drive or four wheel drive. Are there any advantages/disadvant...
