Question by David Watkins

2nd April 2012

QYou state your max efficiency torque as 78.4 g cm. Is this the stall torque from the output of the motor without the gears applied (so a 148:1 ratio would give a stall torque of roughly 11kg cm but obviously reduced speed)?

AHi David, this is the information supplied to us by the suppliers – however I would say that the 78.4g cm applies to the motor only with no gearbox applied. It seems reasonable to multiply this by the gear ratio which comes to 11.6Kg.cm – but this takes no account of any additional inefficiencies that are also introduced. But 11kg would seem a reasonable figure to work with.
