摘要
The device has a stator with a number of polar projections around the periphery of a disc perpendicular to a shaft driven from the engine. A rotor with a second group of polar projections is situated around the periphery of a second perpendicular disc. At least one group of polar projections extend parallel to the axis of the shaft, while the sum of the max lengths of the polar projections parallel to the axis is slightly less than the axial spacing between the discs, to obtain an axial air-gap between the polar projections of the two groups when they face one another. A permanent magnet and a coil surround the shaft and lie between the discs so that the displacement of the rotor polar projections causes ignition pulses to be induced in the coil. The collision between the polar projection is prevented while maintaining the required air-gap.
