<p>1,014,116. Transformers. TOKYO KEIKI SEIZOSHO KABUSHIKI-KAISHA. Feb. 7, 1964 [June 24, 1963], No. 5263/64. Heading H1T. Secondary windings 21, 22, 23, 21<SP>1</SP>, 22<SP>1</SP>, 23<SP>1</SP> (Fig. 4) of a control signal device which supplies a step motor are mounted on polepieces of a stator 44, windings mounted on opposite polepieces being connected in series so that a rotor 24 provides a preferential magnetic coupling between a primary winding mounted on the stator and one pair of secondaries according to its position so that a control signal is delivered from this pair of secondaries. As the rotor rotates, differing pairs of secondaries deliver the control signal to the step motor and only when the rotor is in a position between two adjacent polepieces is a signal delivered from adjacent secondaries. The primary windings 31, 32, 33, 31<SP>1</SP>, 32<SP>1</SP>, 33<SP>1</SP> may be mounted on all the polepieces of the stator or may be wound around a diameter of the stator and the rotor may be in the form of a cross (Fig. 6, not shown). The stator and rotor are made either of laminated magnetic material or of ferrite material.</p> |
