Here is an AC motor and controller package that is reasonably affordable.
Motor, AC Motor & Controller Assembly
Just need a new 96v x 100-200ah lithium pack to go with it!
Would probably drive the Insight at quite good highway speeds.
I've seen a couple of conversions of lightweight cars using the Curtis 1238 AC controller and they worked pretty well. The Axiam one in Uk is a good example. The Honda Insight's excellent CD would help to keep W/hr down to quite reasonable levels.
Fairly simple to make a motor adapter plate and connect it to standard manual gearbox.
Driving the Honda OEM display etc and intergrating it all will be the tricky part. I must get on with the comms analysis project!!!
Affordable AC Drive?

Hi Peter
The link seems to be missing from your post. Is it this one?

Looks like a good package for a small (or slippery) car. Would be even better if the exchange rate ever returns to 2:1.

This motor is the AC31 by HPGC (High Performance Golf Cars). The flat part of its torque speed curve extends to about 1800 rpm (about 99 lb-ft), so peak shaft power is at about 1900 rpm. The same company recently introduced the AC50 motor with the same Curtis controller 1238-75, 550A. The flat part of the t-s curve extends to 3000 rpm (about 90 lb-ft). They gave up a bit of torque at lower rpm to get higher running torque and power. It has considerably higher torque and power than the AC31 at rpm greater than 1900. Peak power for this motor at 96V is 52 HP at about 3200 rpm. Cost is $4500 for motor, controller, wiring harness, and Curtis meter that reads out motor rpm and efficiency based on motor slip (three green LEDs indicate regen, two very good eff, one green good efficiency, yellow poor, red very poor).
I have received one of the first 10 produced and am in the process of installing it in a 2001 Suzuki Swift, 1895 lb curb wt, with 36 180Ah SkyEnergy cells for nominal 115V, 20.7 kWh (the controller has a max voltage of 130V, so I'm pushing it with max pack V of 129V or 3.6V/cell). This nominal voltage should give about 60 HP peak.
At 96V I would expect a top speed of around 150 kph, good acceleration to over 100 kph, and range at 100 kph of over 80 km, based on calculations in a spreadsheet you can download at nevadaelectric.org (referred to as an "ev calculator"). Set the "number of batteries" (cells in this case) to 30 for 96V. AC50 torque-speed is based on dynomometer data from HPGC at 96V. This data was taken with lead acid batteries which sagged to 85V at higher currents, so should be a bit better with lithium. It gives similar performance to the Advanced DC 8" series DC motor with Curtis 1231-77xx, 500A controller, also in the spreadsheet.
