Hi all,
I came across Philippe Hurbain's excellent website sometime ago. On the
Motor Internals page, there is a link that points to Ryo Watanabe's page
containing information on NXT motor parameters. On that page, the torque
constant (Kt) and back-EMF constant (Kb) have rather different values. In
theory, they are supposed to be numerically identical when using SI units.
Naturally, some level of empirical error is expected when data is derived
experimentally. However, the discrepancy between the two values is large
enough for one to question the validity of the data used for deriving the
motor constants.

I've emailed Prof Watanabe a couple of times already without getting a
reply. Could anyone shed some light on this, please? Thanks.
Cheers
Hippie
