I'm most interested in your inverter/controller (and studying it on your page). I'm still weighing the benefits/drawbacks between using IGBTMs for the output, or going with 3 (75kw) amplifiers and true sine wave output. I plan to use a common industrial 30kw (3600 RPM) extreme duty induction motor, wired for 230 V, and control speed in 45 steps (including 50% overdrive for 5400 RPM). Other than size, and cost of the controller; what made you choose an IGBT output?

Not a wise thing to go without...
With cheap, liquid filled lead acid batteries, you could get away with not using a BMS. However, I wouldn't go without one in any battery pack as one of the benefits of using a BMS is a longer battery life. The savings alone would pay for the BMS.
A good BMS is required with all other battery types.

@mrCbeems You MUST be missing something if you don't understand the advantages of 3 phase AC induction over brushed DC.

Hi there, wonderfull conversion you have there! Really inspiring! How do you change the gears if you don't have the clutch? Do you just wait the rews to fall lower then just slot the next gear in or how?

I get the impression that using variable torque instead of variable frequency is preferred for better speed control. Would you say that is the case? I'm shopping for an AC drive now. How important is the liquid cooling of the motor?

Amazing Job, i have been doing research on doing my own conversion. Where did you purchase your motor?
