Abstract
A rotational speed sensor (10) comprising a shaft (54) having a reluctor (50) mounted thereon and coacting with a complementary shaped stator (18). The reluctor (50) and stator (18) have coacting regularly spaced projections (20, 58) which are magnetizable so that as the reluctor (50) rotates with the shaft (54), there is developed a cumulative voltage output which in turn enables utilization of much greater air gaps between the respective projections (20, 58). Because of the greater latitude in the air gaps, it is possible to construct a variable reluctance speed sensor (10) much more economically and with less emphasis on cumulative manufacturing tolerances. This greater flexibility of manufacturing with higher manufacturing tolerances contributes materially to the attainment of an economical and reliable speed sensor.
