Electromagnetic rotational square wave generator - uses cylindrical multipolar permanent magnetic to provide wave form of frequency which is independent speed of rotation

摘要

The generator provides a square wave alternating polarity voltage waveform which remains rectangular irrespective of the operating frequency. The output may be used, after suitable processing, for engine ignition and is taken from a fixed winding (9) which senses the variation in flux in a stator assembly (7, 8) centered on a rotating fixed magnet (6). The flux variation follows a triangular pattern the stator, in a ferrite or iron dust core material, having a comb form extending over the rotor poles. The stator is in halves and is held in position by a non-magnetic cylinder (10) centered on the rotor shaft (1). Similarly the rotor is spaced from and held to the shaft by a non-magnetic cylinder (3). The bearings (11, 12) may be self lubricating.
