Abstract

1461216 Electric motors DAINI SEIKOSHA KK 17 Feb 1975 [21 Feb 1974] 6632/75 Heading H2A An electric motor comprises a permanent magnet rotor la mounted between two stators 4, 5, the rotor and stators being disposed within a magnetic housing 8, the housing and the stators forming a common magnetic circuit. The motor is intended for use in timepieces, the casing 8 serving to shield the rotor from stray magnetic fields.
