Propeller Technology and Hydronamics Anything but off-the-peg:Torqeedo equips top-quality motors with made-to-measure propellers Each and every Torqeedo propeller is tailor-made to match its torque motor: the torque characteristic of the motors supports the use of highly-efficient propellers in a special way.Basically, propellers which slowly turn in the water and have a high pitch and a large diameter, have the highest degree of effectiveness. In order to realise this combination of properties, a high torque at low speeds is required. Torque motors are hence perfect for use with a highly-efficient propeller The torque characteristic of combustion engines, on the other hand, is relatively unfavourable for the degree of effectiveness of the driven propeller, since they only have a very low torque at low speeds. The degree of effectiveness of the propellers which can be used for the combustion engines are therefore limited to 20-30% in low performance categories.
