Today I replaced my older 300 watt BMC with a newer 600 watt Lashout
(which I see was made by BMC). I quickly went out and tried my hill
test and found that I could only climb the same 20% grade hill as my 300
watt motor :-( . My old 600 watt BMC could climb a 40% grade :-) . I
then looked at my Power Analyzer Plus power meter and found that the
stall current at 0 RPM is a mere ~10 amps vs my old BMC's 37 amps...that
would explain the lower hill climbing torque.

It appears that BMC uses a current fold back algorithm based on RPM...as
the rpm drops below a certain number the current then starts to fold
back proportionally. It seems that BMC motors always failed at
start-up...not once they were revved-up. Has anyone found that this new
algorithm increases the reliability of the new BMC motors?

Kind regards,
Tim
