ABSTRACT:
A multiple pole solenoid (10) having outer pole flanges 44a-44d and inner pole flanges 46a-46d magnetically act on outer armature flanges (32-35) and inner armature flanges (36-39) respectively, to move an armature (14) where an AC coil (16) and a DC coil (18) are simultaneously energized by an AC electrical source (20) and a DC electrical source (22) respectively thereby providing a high pull-in force and a high holding force with low noise.
In a second embodiment, a four pole solenoid (48) is comprised of a first AC coil (62) wound on the second pole (56) and a second AC coil (64) is oppositely wound on a third pole (58) and a DC coil (66) is wound on both the second (56) and third (58) poles where the first (54) and fourth poles (60) are without coils and an armature (50) is pulled into the poles (54-60) and held in position by the simultaneous energization of both the AC coils (62,64) and the DC coil (66).
