Question
A 6V DC motor has a stall torque: Tst 0.4 Nm and no-load speed: WNL = 573 RPM. Assuming
zero losses, specify (with proper units with each numerical answer):
1. the torque at maximum power for driving a mechanical load
2. the rotational speed (in RPM) for producing maximum power to drive a load
3. the maximum power (in watts) that is available to drive a mechanical load
4. the gear ratio that is required to most effectively drive a torque load of Tioad = 0.6 Nm
5. the rotational speed (in RPM) of the output shaft of the gear box under the conditions of # 3
and #4
6. the linear speed (in inch/sec) given the shaft (from #5) drives a 6 inch diameter wheel
