This is my first post to this list/forum, so please bear with me. I am a collector of old VWs, and I had long known that VW had developed EVs in the '70s, and I always wanted one. A friend of mine came up with one a few years back, and I bought it from him. It is a 1979 VW bus which was originally owned by the Tennessee Valley Authority. They bought and tested ten of these vehicles in 1979. (NASA tested one in '77). I know many things about VW buses, and I am fairly mechanically inclined, but I know next to nothing about this drive system. The bus has been off the road for 20+ years and I am trying to get it going with as much of the original drivetrain as possible. I hope that someone has some knowledge of this system and how it works.
The sparse technical literature that I have shows that the Motor is: Siemens 1 GV 1161-Z and the controller is a Siemens 6 RB 1000-1BA The literature says that it has regenerative braking. The transmission is set in 2nd gear permanently. I turned the axles, and the motor turns. It is designed to run on 144 volts, but it is supposed to work from 110v-170v. I strung 11 12v auto batteries together and got 137v The volts make it to the connection at the controller, and I turned the ignition switch on and press the accelerator and nothing happens. This is where my expertise runs out. I can run a multi-meter, and I know how electricity works in general, as I can and have made every part of the electrical system work on any number of old 6v Volkswagens. The questions I have are: 1) Does anyone here have working knowledge of an ancient Siemens controller? 2) How does the regenerative braking work? 3) the literature says that it is a shunt wound DC motor. Can I test the motor by supplying voltage directly to it? If so, how much voltage should I use to test it? Thanks in advance. -- Sent from: http://electric-vehicle-discussion-list.413529.n4.nabble.com/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
