If you want proper temperature readings, an easy way to get consistent results is to isolate the motor (possibly with the load creator as well) and then monitor changes of the ambient temperature in the isolated box, or container, or whatever. You will probably need a fan to expedite the transfer of heat to air, and would also need to ensure that other things in the box generate minimal amounts of heat. Then, you can just measure the change in temperature.

As for the load creator, I think a great idea would be a prop in water. However, most importantly, you must find a way to make sure NO air gets inside the water and near the prop, as it will change the overall density of the water in that area and lighten the load, producing varying readings.

You may also want to make some sort of way of preventing different gearing from affecting results.
