Abstract

1518886 Stepper motors DAINI SEIKOSHA KK 8 July 1976 [6 Aug 1975] 28459/76 Heading H2A A stepper motor includes a one-piece stator 2 having a core portion 1 with a coil 10 thereon, the stator 2 determining an angular rest position of a rotor (not shown), and forming with the rotor a closed magnetic circuit. In the arrangement illustrated, pole-bridging sections 11, 12 distort the magnetic field and so determine a rest position of a rotor. Sections 11, 12 could alternatively be omitted.
