Hi BengKiat
There was a recent project in an electronics
magazine that monitored back emf for motor speed control using a PIC
microprocessor and an H bridge. The project was for a model train
controller.
I have scanned in the relevant parts of the circuit
and description and put them on my website as the file is large (around
8mb)
It is in Microsoft PowerPoint format which I'm sure
you can read OK
You can access it at
It takes a while to download, so be
patient.
Hope this is useful to you and anyone else that
wants to try out this technique.
Cheers
David Hannaford

Subject: Back emf control of DC
motor
Hi all,
Has anybody done any work on bemf control on dc
motor?
I'm looking for working circuits or ideas to extract the bemf
from the H-bridge. Tried to design one but was not successful. Not as easy as
it appears to be. Any help will be appreciated.
Regards
BengKiat
