AC induction, DC series, PMAC, PMDC...there are a lot of motor types out there. I'm starting this thread to nail down the pros and cons of each. I don't expect to come away with any absolutes like "type X is the best". More like "if you have this setup, these expectations, and this budget, you'd do well with type X, or maybe type Y"
This site claims:
"[AC induction are the] Third most popular electric car motors, but if all motors cost the same, these would be the hands-down winner. Why? Because they're better. (There, yes, I said it. I took a stand."
MetricMind says essentially the same thing.
And this writeup compares induction and BLDC (aka PMAC), stating:
"Back when I had hair on my head and carried a slide rule, there were lead acid batteries, DC brush motors, and contactor controllers. Today, none of these remain (including my hair)."
Then basically says PMAC are good for efficiency (think hybrid), AC induction are good for high-end performance (think Tesla).
But, we know that PM-DC motors are very popular for electric motorcycles. AC induction looks superior on paper, but it depends on the batteries, gearing, and all sorts of other factors. The Killacycle uses series motors.
Given all this, how should someone decide what is best for them? That's what this thread is about.
