ABSTRACT:
A method of joining a magnetic armature of an electromagnetic actuator to a shaft is provided. The method includes holding the armature stationary while spinning the shaft. The spinning shaft is then pressing against the stationary armature such that friction between the shaft and the armature causes a portion of the armature and a portion of the shaft to melt and define a weld joint. The weld joint is permitted to cool thereby joining the shaft to the armature.
