Abstract
A non-commutated linear motor particularly suitable for use as an electric door lock actuator for an automobile is disclosed. The linear motor may include a series of cup-shaped portions each having a winding appropriately connected to provide the desired travel stroke, in a direction determined by polarity of D.C. power applied to the winding, and power for the linear motor or a segmented armature designed to achieve the same flexibility in motor design and assembly.
