control of 3 phase dc brushless motor

so I just bought my first Duemilanove and I am pretty excited
about getting started with hardware hacking..

anyway I have a motor I would like to control
it appears to be a 3-phase DC brushless motor

the motor is attached to a board that is part of an actuator

some additional info I was able to dig up:

There is an ST microprocessor on the board that runs a Freescale motor control chip. The chip controls the 6 MOSFETs on the top of the board

There are 3 hall effect sensors in a cage around the brushless motor.
A serial bus EEPROM is on board and may contain some usable program data.

I am fairly sure its setup to be controlled via the CANbus protocol

is there a way to use this motor and part of the motor controller

a picture of the bottom of the board:

more information from the original manufacturer (Delphi)

here is the bottom of the controller
the three prong ring is the hall sensors

and the actual motor:

would it be eaiser to scrap the controller board
(with the exception of the hall sensor ring)
and build my own ?

how would I control it with an Arduino ?

I cant believe I stumbled upon this, are you still working on this? Looks like a delphi controller for a 351VE VGT turbo controller. I have also taken one apart, and have settled on controlling the motor manually, rather than intercept/inject a signal on the board.

I have found this document online which I think can help.

Hello.
I'm also in the early stages of using my arduino to control a VGT.

How do you guys do this?

oel_brenner -> I saw on an other forum that you intended to use a fairly large stepper, how is that working for you?

simsumdum -> Do you still use the factory DC-motor? I saw in an other thread that you were asking questions about reading 3 Hall, so I take it that you hang on to the brushless motor?

Pictures? Updates? Links?
