The diagram you give is for a fixed frequency induction AC motor. The inverter puts out a variable frequency, so is rather different. There are two areas of interest: Torque limited, when the inverter is outputting the maximum design current, and power limited. This diagram is for a Tesla Roadster, but should be fairly similar in shape (but the peak torque and power are different, of course: 92 kW (125 PS; 123 bhp) and 181 lb·ft (245 N·m) of torque.[):az erik wrote:You're right it's a AC motor. Those actually do provide 100% torque at full speed. They deliver 100%+ from break torque and pull up torque, which makes the "100% torque" true. Which is better than 300% torque off the line.
Reason I got all wrapped up in DC is the EMW and a few others conversion kits I've been looking at use DC/DC. Makes me wonder just how much AC voltage is coming out of this battery. I thought I saw the battery at 480 volts or so.
