So I purchased the following motors and wheel caster (links below).
and planning to use a lightweight sheet of wood for chassis.
How can I know whats the appropriate weight the motors can hold/run, like will they be able to hold a 7 pound laptop? What is the range of weight they can hold? how do I calculate it. Thank you
Motor Ratings (at 7.2 VDC):
No-load Current: 0.27 A @ 310 RPM
Stall Current: 4.8 A
Max Torque: 4.6 lb-inch (5.3 kg-cm)
Does it mean I can't go over 4.6lb?
