Abstract

A pivoting armature which functions as part of an electric control motor is rotatably supported on a shaft in a housing of the electric control motor and has a pole carrier on which pole shoes are mounted, the pole shoes being joined to the pole carrier in a rotationally fixed manner. The pole shoes can be produced by sintering or welding on a pole shoe ring that is pressed onto the pole carrier, or by stacks of laminates.
