help on starting a project on BLDC

[pmm]

Hello every body
I told to start up a project on BLDC motor postion control system this
would be my first project based on motor control,can any body please
guide me in some aspects which are needed to start the project ,I have
browsed through the net and downloaded few of the documents on BLDC
motor makes ,few on PID implementations . My design should be based on
CAN and Devicenet protocols . the Motor should be 3-4amps 24v . the
thong which is stopping me is where to start and what to start i cant
run into it blindly with out a proper direction . so i am looking into
this group to give me a start up idea of designing it and embedding
code into it

the aspects are what encoder shall be selected for the protoboard shall
be cheap and easy to work on
do i need the tachometer or just counting the encoder reply will do
and any suggestion on your own which help me to execute this task

thanks & regards
PMM

Hello Mr Paul
Thanks for your reply ,
I was reading thru the PIDs questions posts
in the forum,and I feel like its pretty tough to implement them , how
do I test them, is there any demonstration tool ready so that I can get
one to test them.
any ideas from your side on those algos , will help me a lot

thanks and regards
PMM
