ADC produces a shunt 8" identical in size and performance with their 8" series. Works with sepex controllers.
Main problem with shunt/sepex combination, typically half the voltage of series/dc systems. So requires more amps throughput to generate equivalent power for freeway speeds. 96v-500a (48kw) sepex controller might be equivalent throughput to 144v-333a (48kw) series, except sepex offers regen for braking and energy recapture as levels that the shunt motor doesn't arc. So far the max rating I found for sepex controllers is 96v-800a. For series controllers, have seen some 144v-800a and 144v-1000a (or DCPs rated at 156v-600a, 156v-1000a & 156v-1200a) BR, Ed Thorpe -----Original Message----- From: Peter VanDerWal [mailto:[EMAIL PROTECTED]] Sent: Monday, September 30, 2002 10:05 PM To: [EMAIL PROTECTED] Subject: Re: SepEx Motors and Controllers for EVs Yup, though they seem kinda hard to get ahold of. GE made some sepex motor/controller combos before they quit the ev bussiness, unfortunately they wanted you to buy at least 5 of them at a time IIRC. Kostov makes sepex motors and ZAPI makes sepex controllers. Curtis does too, but I'm not sure if they make any EV size ones. I think their are a few others out there too.
