EV airconditioning

[Art Mander <ARTMAN@TRISTATEGT.ORG>]

     When I had the Solectria Force for the weekend, I took a look at the
     air-conditioning.  They use a small 144V, 1.5 hp brush motor mounted
     next to the original air-conditioning compressor.  It drove the
     compressor directly with a cogged belt, but no clutch.  All of the
     original refrigerant and control stuff was left as is, with the only
     change being that when the system needed the compressor, instead of
     kicking on the clutch, it would run the 1.5 hp motor.  The system
     worked well, and had the advantage of full air-conditioning regardless
     of vehicle speed.  I would guess that in order to handle the startup
     torque, it was a series DC motor.
