Latest Patents
One of Jens Steffen's latest patents is a power electronics unit designed for driving an electric machine excited by permanent magnets. This unit includes a rotor and a stator with at least one stator winding. It features a power switch that drives the stator winding and an overvoltage protection device to safeguard the power switch from overvoltage. The overvoltage protection device consists of a phase voltage detecting device linked to the power switch, along with a short-circuit switching circuit. This circuit activates when a predetermined phase voltage threshold is reached, short-circuiting the stator winding associated with the power switch.
Another significant patent is for an electric machine that comprises a rotor equipped with permanent magnets and a stator with electromagnetic poles. This electric machine is characterized by several adjacent electromagnetic poles forming an electromagnetic pole group, spaced apart at a first electromagnetic pole spacing. Adjacent electromagnetic poles from different groups are spaced further apart, and each group contains an even number of poles. This design allows for the generation of magnetic fields of opposite direction during operation.
