Rotation identification device for a commutator motor

摘要

According to the invention, a simple and cost-effective rotation identification device for a commutator motor is produced in that the rotor shaft (5) has a permanently arranged magnetic rotor body (29) in the intermediate space between the commutator (21) and the bearing (15) in the bearing plate (11), which rotor body (29) can be scanned by a Hall sensor (37) which is arranged on a printed circuit board (41) designed as a push-in component. The printed circuit board (41), which is fitted with electrical components, can easily be installed and removed (assembled and dismantled). <IMAGE>
