Abstract

1,196,418. Linear motors. ENGLISH ELECTRIC CO. Ltd. 8 Sept., 1967 [26 Sept., 1966], No. 42841/66. Heading H2A. [Also in Division H1] A bi-stable electromagnetic actuator for a vacuum switch comprises a permanent magnet armature 1 and four annular energizing coils 15, 16, 17, 18. The coils are connected in parallel to a supply, rectifiers preventing the operation of all four coils at once. When a pulse of the correct polarity is applied to the actuator, coils 15, 16 and 18 are energized in the same sense and the armature 1 is moved from the upper position shown to its lower position where it engages an annular polepiece 13. When a pulse of the opposite polarity is applied coils 15, 16 and 17 are energized and the armature 1 moves to the position shown. The length of the pulses is sufficient to prevent bouncing. The permanent magnet may be replaced by an electromagnet. The flux diverting coils act in succession on the armature 1 to divert the permanent magnet flux so that the length of movement may be increased by the addition of further flux diverting coils.
