Electric Car Motor (for AC Conversion)

Part 2...

OEM Electric Car Motor for AC Conversion

"Electric Car Motor for AC Conversion" is Part 2 of a three-part interview with Eric Tischer about his AC conversion. You can read Part 1 here.

Lynne: I notice that you chose an electric car motor that, you know, came out of an electric car - an old Ford Ranger EV - rather than any old industrial 3-phase motor. Was there a reason for this?

Eric: The motor I chose was used in an electric vehicle and it is much lighter and smaller than an equivalent industrial AC motor. The electric car motor is water cooled, which makes it much smaller than air cooled motors which require heat fins. Industrial motors are also rated for continuous power, which causes it to be much larger than an electric car motor rated for intermittent duty which is better suited for an EV. The electric car motor is also sealed liquid tight, and somewhat stubby, a 90hp industrial motor would probably stick out beyond the front bumper, and weigh 400 lbs.

Lynne: Why do you run your system at 300
