AM-0915a for Drive Motors?

[AlisAquilae]

I am working on another project and would like to use the AndyMark PG27 Gearmotor (AM-0915a) as the direct drive motor for the drivetrain.

Using a quantitative analysis I found that the margin of safety between the stall torque of this motor and the theoretical needed torque to drive a 40lb, four-wheeled robot is approximately 0.3.

I'd like to know if anyone has used this motor in the past to drive the wheels on a robot or if the forum believes that it will have the power to drive a 40lb robot.

Two of these motors will be used to drive each of the 6" rear wheels. We are using a 4mm key and the AM-0985 hub to drive a 6" AM wheel.


Thanks!
