Beschreibung
Zusammenfassung:	A device including a number of printed circuit board layers assembled in a stack that functions as a starting device for an internal combustion engine. Each of the circuit board layers includes a number of loops formed by copper traces on a dielectric substrate and each oriented in a coiled pattern. A rotor, which may take the form of a flywheel, is closely spaced from the stack of printed circuit board layers and includes a series of permanent magnets. When alternating current is supplied to the circuit board layers, the magnetic fields created by the loops induce rotation of the rotor. The device can operate in an alternator mode in which the device generates current as the rotor rotates past the loops on the circuit board during operation of the internal combustion engine.
