Hi all,

I will have a URL I hope soon to post for a PhD thesis on a motor controller
designed for 3phase brushless DC motor control, IIRC the paper discused a
design for a 120Vdc system and has been used in a number of solar cars. I am
hoping to improve on it using an AVR (ATMega128) as it does high speed PWM.

Will pass URL on when it arrives :o)

Regards,

Kat.
