The Gravitational Motor is a type of motor which converts Gravitational Energy directly into Rotational Kinetic Energy. Its fuel is therefore the Gravitational Energy (no needs gasoline, oil, etc). An example of Gravitational Motor is the turbines of the hydroelectric plants. However, they are not mobile i.e., they cannot be transported from one place to another as the combustion motors or the electric motors. Mobiles Gravitational Motor can be developed starting from the devices of gravity control, such as the Quantum Controller of Gravity (QCG) [1]. The form of the QCG originally proposed is spherical. Here, it is described a Gravitational Motor which uses a QCG with spherical cylindrical form. This Gravitational Motor can have very-high power, and it can be used in order to generate electrical energy at large scale or traction to move cars, ships, tankers, aircraft carrier, trains, etc.
