Historically, yes, but as of late the cost of Inverters has dropped quite a bit.
But, given the weight advantages and the fact that they're a bit more pokey I'd go for one

Hi Nikki,
What sort of costs have you found for an AC motor and controller?
The best I can find is Metric Mind and Evisol. Thier AC motor and inverters are £6K plus batteries. This is 3 or 4 times the cost of a DC setup.

Sepex motors offer all the advantages of AC, regen braking high effientcy etc but a the same cost of a series DC setup.
Cheers,
Ian
