Abstract
1463223 Stepping motors DAINI SEIKOSHA KK 19 May 1975 [25 June 1974] 21286/75 Heading H2A In a stepping motor comprising a permanently magnetized rotor 5 and a wound stator having a pair of pole pieces 3, 4 with part-cylindrical pole faces 3a, 4a, a recess 12a or 12b is provided in at least one of the pole faces 3a, 4a, and a bush 24 is used to locate the pole pieces 3, 4 on a mounting plate 22 so that the pole faces 3a, 4a are coaxial with the rotor 5. In the motor shown, the bush 24 is fixed in an aperture 23 in the plate 22, and supports one of two rotor bearings 20, 21, and as a consequence of the recesses 12a, 12b the rotor 5 can only rotate in one direction if a pulse train such as in Fig. 6 (not shown), is delivered to a stator winding 1. The recesses need not be opposite one another, and may have various other shapes, e.g. as in Figs. 7A-7F (not shown). The motor may be used in electric watches (no details).
