Abstract
In one of its aspects the technology disclosed herein concerns a process of making a rotary solenoid. In a generic mode, the process comprises fitting together two mating core half members (A,B) of a stator until two respective pole faces (A,B) of the two mating core half members (A,B) press to a positive stop against a precision diameter pin positioned between the two mating core half members and so that the two mating core half members interlock at the positive stop. The process further comprises removing the precision diameter pin to provide an axially extending space comprising a predetermined distance between the two respective pole faces (A,B). The process further comprises inserting a rotor () within the axially extending space. The process further comprises fitting the two mating core half members (A,B) and the rotor () between the two opposing end caps (). The act of fitting the two mating core half members and the rotor between the two opposing end caps preferably comprises aligning the two pole faces (A,B) with pole face alignment features provided on the two opposing end caps whereby the two pole faces are retained at a predetermined position relative to the rotor.
