A123 Systems have not responded to my emails, unsurprisingly. Also, have you talked to Zytek/Bosch/Magneti Marelli about a brushless system? All three developed extremely light-weight brushless motors for F1 KERS. Maybe they would be interested in sponsoring your upgrade. I meant the “f1″ cells mentioned in this post.

The cells in the KillaCycle are standard production A123Systems 26650 M1 cells. You can purchase a developer’s kit from A123Systems here.

The M1 cells are used in Dewalt 36 volt lithium ion cordless tools.

Just give me the specs for a free quote. For extremely high power I suggest a brushless PM multipole design using FeCo laminations and a Halbach magnetic array.

Maybe they would let you use it? <em>As I recall, they used either one, or possibly two, AC Propusion drive systems. They are about 150 to 170 kW each. (200 to 230 HP) but the inverters are very large in size and cannot fit on a motorcycle. (Bout the size of a _very_ large suitcase.) We need 1000 HP in a compact package. AC Propulsion seriously considreed building a 1000 HP drive package specifically for the KillaCycle. They _wanted_ to do it, but they just couldn't justify diverting the time and money away from their pressing business needs. Basically, they had to be "adults", even though they didn't want to be, and take care of businees before they could allow themselves to have "fun" doing a 1000 HP motorcycle drive package.</em> What about the original Buckeye Bullet AC induction motor.
