Abstract

1339817 Electric motors; core constructions FUJITSU Ltd 24 Nov 1971 [3 Dec 1970 29 Dec 1970] 54551/71 Heading H2A A stepping motor comprises circumferentially spaced pairs of axially aligned U-shaped laminated stator cores 13a, 13b, disposed on opposite axial sides of a toothed rotor 6, each core carrying a winding 12a, 12b, and having on its end face adjacent the rotor teeth, teeth of the same pitch as the rotor teeth. Spacers 15 of magnetic material are disposed between the axially aligned cores and the cores are secured to a casing 16,17, by an adhesive, e.g. a synthetic resin adhesive.
