1. Apparatus for selectively deforming a first portion of a workpiece and recognizing said first portion, said apparatus comprising:
- means for deforming said first portion of said workpiece by a predetermined amount sufficient to distinguish said first portion from a second portion of said workpiece;
a sensing member;
means coupled to said sensing member for moving said sensing member a predetermined distance relative to said workpiece to cause said sensing member to contact and apply a force to said workpiece;
means for monitoring the force exerted on said sensing member; and
means responsive to said means for monitoring for distinguishing said first portion of said workpiece from said second portion of said workpiece on the basis of the monitored force, to recognize said first portion.

Abstract
Methods and apparatus for marking and identifying a commutator hook of an electric motor are povided. A preselected commutator hook is marked by deforming the hook while the armature is in a winding machine, with a known angular position. The marked hook is identified by apparatus which determines whether or not the hook has been deformed while in the winding machine, and thereby recognizing the hook.

13. The method of suing a deforming member to deform a first portion of a workpiece and a sensing member to recognize said first portion, comprising the steps of:
-
moving said deforming member relative to said workpiece in order to cause said deforming member to contact and apply force to said first portion, to deform said first portion and thereby distinguish said first portion from a second portion of said workpiece; moving said sensing member relative to said workpiece to cause said sensing member to contact and apply a predetermined force to said workpiece; monitoring the relative motion of said sensing member and said workpiece; and distinguishing said first portion of said workpiece from a second portion of said workpiece on the basis of said relative motion to recognize said first portion. - View Dependent Claims (14, 15, 16, 17)

23. The method of using a sensing member to determine whether a preselected hook member of a workpiece is wrapped with a single wire, comprising the steps of:
-
moving said sensing member relative to said workpiece to cause said sensing member to contact said preselected hook member and thereby deform said preselected hook member by a predetermined amount; monitoring force exerted on said sensing member when said sensing member has deformed said preselected hook member by said predetermined amount; comparing said monitored force with a predetermined force value representative of the force resistance exerted by a typical hook member that is wrapped with a single wire; and recognizing said preselected hook member as a hook member that is wrapped with a single wire if said monitored force and said predetermined force value are substantially equal. - View Dependent Claims (24, 25)
