<p>An electromagnetic actuator is provided and includes upper and lower electromagnets. Each electromagnet includes a lamination core assembly comprising a plurality of individual stacked laminations. Upper and lower housings are provided, each having opposing end walls. The core assembly of the upper electromagnet is disposed between the end walls of the upper housing and the core assembly of the lower electromagnet is disposed between the end walls of the lower housing. An armature is mounted for movement between t he core assemblies. Spacer structure is disposed between the core assemblies and contacts each of the core assemblies to prevent the core assemblies from moving towards each other. A pin provides a connection between a lamination core assembly and the end walls of an associated housing. Each housing has a contact surface between the end walls and each of the core assemblies includes a solid core member defining a central portion of each core assembly. Each of the solid core members is secured to a contact surface of an associated housing via at least one fastener. A method of joining a lamination core assembly of an electromagnetic actuator to a housing of the actuator is also provided.</p> |
