Electromagnetic actuator with split housing assembly

摘要

A method of securing a core of an electromagnetic device to a housing assembly is provided. The core includes a stack of a plurality of laminations. Each of the laminations has a plurality of apertures extending therethrough which cooperate to define a plurality of apertures through the core. The core has generally planar ends. The housing assembly includes first and second housing portions constructed and arranged to receive the core. Each housing portion has first and second opposing surfaces with the first surface defining a generally planar contact surface. Each housing portion includes a recess extending inwardly from the contact surface and a plurality of apertures extending from the first surface to the second surface. The apertures in the housing portions are disposed at locations corresponding to locations of the apertures in the core. The method includes arranging the core between the first and second housing portions such that the apertures in the housing portions align generally with the apertures in the core. A fastener is then inserted through each of the apertures in the first housing portion, through each of the apertures in the core and through each of the corresponding apertures in the second housing portion in such a manner to secure the core to the first and second housing portions with each planar end of the core being engaged with an associated contact surface. Each end of the core defines, in cooperation with an associated recess, a coil receiving space for receiving a portion of a coil of the electromagnetic device.
