Title: Ewald Wehner: Innovator in Electric Motor Technology
Introduction
Ewald Wehner is a notable inventor based in Wurzberg, Germany. He has made significant contributions to the field of electric motor technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
Wehner's latest patents include a device and procedure to adjust the axial play between the rotor and the stator sleeve. This invention develops an automated procedure that allows for the settling of the axial play of a rotor using a stator sleeve pressed onto the rotor shaft. The design is held in place during assembly by an insulating end disc that mates with the laminated rotor core, ensuring minimal assembly steps. The insulating end disc is injection-moulded in one piece along with the spacer sleeve, featuring intermediate weak rated points that allow for relative setting motion. This invention is particularly suitable for small commutator motors with rotor shafts mounted in sleeve bearings.
Another significant patent by Wehner is the commutator motor brush mounting arrangement. This arrangement is designed for an axial opening of an electric motor housing and includes mounting bars that protrude axially from a support plate. Hammer-shaped brush holders, formed with half-open bearing shells, are rotatably engaged with the mounting bars. The design prevents axial displacement of the brush holders, ensuring efficient operation within the motor housing.
