Abstract

An actuator can include a housing, core assembly, and first and second electromagnets. The housing can have a first pole piece, second pole piece, and central pole piece disposed between the first and second pole pieces. The central pole piece can have a central body and a bridge. The bridge can be between the first and second pole pieces and axially movable relative thereto. The core assembly can be received in the housing. The core assembly can be movable along a first axis between a first core position and a second core position. The core assembly can include a permanent magnet, a first core, and a second core. The first and second cores can be coupled to the permanent magnet for common axial movement. The first and second electromagnets can be spaced axially apart by the central body and can have opposite polarities.
