Electric motor with brushes and power of 55 watts, can be powered at 120 Vdc and features a rotation speed of 2500 rpm. Engine dimensions (mm): 72x51x34, shaft: Ø 8x34, weight: about 480 grams. It has a very low resistance to the rotation of the shaft, so that it is possible to rotate it effortlessly with the fingers of one hand, obtaining a discrete output voltage. The applications for this engine can be very many, since it can also work as a dynamo; in this case the simple rotation movement of the crankshaft allows to produce electricity, as well as it can generate mechanical movement (rotation of the crankshaft) if powered from the outside. It will therefore be possible to make a crank or pedal operated current generator, as in the bicycle.
