Microgenerator Provided With a Clutch System, Stand-Alone Electric Device Provided With an Integrated Microgenerator

Provided is a microgenerator of a flat design including a base plate having an external side and an internal side; a stator which is a circular multipole metal stator coil for producing an electric voltage, which stator is fixedly positioned on the internal side of the base plate; a rotor wheel including a circular multipole magnetic array, which rotor wheel is rotatably positioned on the internal side of the base plate; and an actuating system for rotating the rotor wheel. The actuating system includes an input mechanism provided at an external side of the base plate which input mechanism is preferably movable in two directions, and a rotatable rotor shaft which has a concentric orientation to the rotor wheel. The rotor shaft is drivingly engaged with the input mechanism either in a direct or indirect manner. A first side of the rotor shaft is provided with a rotor gear wheel that is in driving engagement with the input mechanism either in a direct or indirect manner, and a second side of the rotor shaft is drivingly connected to the rotor wheel. The actuating system is provided with at least one clutch system to establish a unidirectional driving engagement of the actuating system with the rotor wheel.
