Latest Patent Applications

Frank Hartmann has submitted several patent applications, including a significant one for an electric motor featuring an angle sensor. This electric motor design incorporates a main body, a hood part, a holding part, a first circuit board, an intermediate flange, a second circuit board, a disk part with a dimensional scale, and a hollow shaft. The rotor shaft of the angle sensor is connected to the rotor of the electric motor for conjoint rotation. The disk part is slid onto the hollow shaft and bears against a shaft step or a flat surface region of the hollow shaft. The second circuit board contains conducting tracks that act as coil windings and is held clamped between the main body and the intermediate flange. The intermediate flange is pressed towards the main body by the screw head of another screw that is screwed into a threaded bore of the main body. The first circuit board is held clamped between the intermediate flange and the holding part. The screw head of a screw screwed into a threaded bore of the intermediate flange presses the holding part towards the intermediate flange. Additionally, an elastically preloaded sheet-metal part supported on the hood part is disposed between the holding part and the hood part.

Conclusion

Frank Hartmann's work in electric motor technology, particularly his latest patent applications, showcases his innovative approach to integrating angle sensors into motor designs. His contributions may pave the way for advancements in electric motor efficiency and functionality.
