This is my third attempt to do a posting, never seem to know how to post anything but here goes . . .
Are there any affordable controllers for a DC motor and what rating of motor do I need to propel a 3/4 ton pickup to 60 kph with a 1500 kg load on board (Max practical GVW in Imperial measure would be around 10,000 lbs). My idea of an "affordable" controller would be around $200 - 400.
If more than one (identical) motor is run off the same controller, does it have to handle twice the load or is there a trick to get around that?
I am thinking I may have to design my own controller to get something that does not require a degree in rocket surgery to just hook it up.
I have a question about transmissions. I remember some of the locals having automatics with clutches (clutchomatic was the term I heard), other than being somewhat expensive are they practical for an EV?
Also I have questions about regen. Has anyone ever made a setup with alternative propulsion systems in an EV?
I remember reading about a teacher or professor a long time ago who had a Pinto that he drove into a parking lot, shut the engine off, then drove away.
Uphill.
He had fitted the Pinto with a flywheel under the car that was spun while decelerating. Not that I want a potential shrapnel spreader and gyroscope under my butt, however what if the regen also wound some kind of clockspring or rubber band, as well as charging batteries. That way my truck would have an easier time accelerating up a hill with a heavy load from a full stop, possibly utilizing the front axle of a 4X4 and the electric on the rear axle.
