Does anyone have any information on how the fan is controlled
and what type it is ?

it appears to be a brushless DC design, but how is it controlled by the computer ?
PWM ? CANbus ?




part number is:
930-0015-11 ( I think)

so there are four connectors

obviously the two large ones are power and ground
and the two small ones are control.. but is one data/PWM and the other feedback (like RPM )

or both data etc...

 

mine works... (its brand new)
I am trying to figure out how it works..

like how to control it without the jag computer
what protocol/control messages etc it uses..

 

sorry, I am a bit confused...

I think what you are saying....

large connector: (on right in photo)

right conductor in photo - Brown/green stripe - large 10GA wire - Ground
left conductor in photo - Black - large 10GA wire - 12V+ power to fan

Small connector:

right conductor in photo - White/Blue stripe - small 18GA wire - 12V+ power to module
left conductor in photo - Green/Blue stripe - small 18 GA wire - PWM from ECM


you say it is definitely controlled with PWM ?
thats great !
do you have any other information on the PWM signal ? does it just control RPM ?
frequency range ?

thanks !!

 

sorry.. one last clarification

my motor power connectors
(large conductors, right side of photo)

are brown with green stripe
and solid black

which one is ground and which is 12 + ?

thanks again !!!
