Main Question or Discussion Point

Hi.

I am designing a model for a vehicle. The power source is solar energy, providing power to a single 12 volt motor of about 1W. Through tests I have calculated the stall torque and max RPM of this motor, and therefore a rated torque of 0.00154 Nm. At this load the motor should ideally spin at 6000 RPM (according to tests). It is therefore necessary to use a gear system to increase the torque at the wheels and reduce the RPM so that the model is able to start moving without a clutch, and maintain a desirable speed when moving. The model weighs 8Kg and has 4 wheels of radius 4.5cm. There is no target speed, we are just aiming for maximum efficiency.

My question is, how do you calculated a gear ratio for a single gear, so that the model will move efficiently and that the motor is loaded to its rated torque.

Any help would be much appreciated!
Thanks in advance,

Ben
