What controller can drive this motor? I used to own an S10 truck with an AC induction motor, driven by a WaveDriver controller that was spec'ed 700V, 250A but that was 3-phase AC using 1200V IGBTs. Of course, it is possible to make a DC controller that does 500V using 1200V IGBTs, but designing and building your own high voltage controller is not trivial.
I do not know of any high voltage controller doing 500V, although if the battery pack could be split in a multiple sections, a contactor controller could be combined with the SEPEX control to give rather smooth behavior (decrease field current while accelerating and doubling the field at the moment you double the Armature voltage for the next step in the contactor control). The contactor controller itself is old skool technology, the combination with the field control might be the most challenging part. But there is a reason all commercial EV have an AC motor.... (now, my EV does have a DC motor - at 120V) Cor van de Water Chief Scientist Proxim Wireless Corporation http://www.proxim.com Email: [email protected] Private: http://www.cvandewater.info Skype: cor_van_de_water Tel: +1 408 383 7626 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jeff Major Sent: Monday, August 12, 2013 11:55 AM To: Electric Vehicle Discussion List Subject: [EVDL] S.E.P.X . controller for 500V , 450Amp Motor ----- Forwarded Message ----- From: Jeff Major <[email protected]> To: Electric Vehicle Discussion List <[email protected]> Sent: Monday, August 12, 2013 12:12 PM Subject: Re: [EVDL] S.E.P.X . controller for 500V , 450Amp Motor So what controller was this project manager planning to use?

The problem is, the project manager has already bought the motor. A 2600lbs Monster, a S.E.P.X. 500V, 450 amp.. its name plate says Armature 500v, 460amps and the field , 300V, 6 amps. We spun the motor over with a 12V battery, and it does run. Any ideas on what I can do for a contoller for this? Regen if possible. Is there some way we could use something like the Soliton and a small controller for the Field?
