Actually, the speed capability is restricted by the fixed single reduction ratio of the drivetrain (top speed compromised for acceleration/gradability), and the intended application; it is not indicative of the drive's potential. Randy had at least one of his MightE trucks geared for highway use (50mph or so top speed, I believe). >They use 96 V, 500 A controllers. >(Zapi controller, Kostov motor, I think.) > Is it fair to assume a 96V sep-ex road EV would have similar > performance to a 96V series setup? No. Mike Holmquist test drove a 144V series DC (Curtis controller, so 400-550A depending on model) conversion back-to-back with a 96V 500A SepEx (both pick-ups) at Randy's place and found the SepEx to perform better... enough so that he purchased a 96V SepEx drivetrain for his Citroen conversion. Cheers, Roger.
