MFA 950D Series Spur Geared Motor Single Ratio Metal Geared 35mm

<p>A range of high quality motors that feature single ratio metal gearboxes with sleeved bearings, enabling the transfer of high amounts of torque from the motor, through the spurred gears, to the 6mm keyed output shaft. The powerful, high quality motor features five poles with carbon brushes and sintered bronze bearings.<br/><br/> This robust motor and gearbox is designed for use in heavy-duty industrial applications. Mounted on a 1mm thick plated steel bracket this range of motors, available in a selection of ratios, are ideal for when a lower current consumption is required.<br/><br/> </p>

Q. Do you stock any suitable wheels that will push onto the shaft of this motor?
A. Thanks for your enquiry Paul. I'm afraid we do not stock any wheels which would fit the shaft of this motor.

Q. You 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)?
A. Hi 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.
