Abstract

A rotation detector has a one-piece universal brush rocker that includes a supporting body that is injection molded, particularly out of plastic. The measuring coil is held on the supporting body between the pole gaps of pole units on the stator side and the measuring coil's winding ends connected to the stripped ends of the brush shunts are cast in the universal brush rocker. This rotation detector guarantees a contacting between the winding ends of the measuring coil and the brush shunts retained on the brush rocker of the commutator motor, and features ease of assembly and lasting operational reliability.
