Lecture on DC motors to Duke ECE 148 class, Feb 20, 2004
Presentation to Sierra Club on EV History, Jan 9, 2002
| I have converted a 1988 Chevrolet S-10 pickup to electric power. It is whisper-quiet, and even better, when it is stopped, it is off -- there is no concept of idle. To charge it I plug it into a normal 120-volt receptacle. Before I converted it, fuel costs were 8 cents per mile; now they are 3.5 cents. I spent about six months on the conversion, working 20 hours per week. | |

The photo on the left
shows the
engine compartment. It contains the motor, a black and silver
cylinder
in the lower portion of the photo. The motor is bolted on its
right
to the front of the standard transmission. Also visible on the
left
is a portion of several of the 20 lead-acid batteries that store
electrical
energy. The motor controller, a black rectangle in the upper
portion
of the photo, delivers the appropriate amount of power from the
batteries
to the motor, determined by how far the driver has depressed the gas
pedal. Lecture on DC motors to Duke ECE 148 class, Feb 20, 2004 Presentation to Sierra Club on EV History, Jan 9, 2002 |
