Electrodynamic Drive
Patent No. EP3535837 (titled "Electrodynamic Drive") was filed by Hilti on Dec 6, 2017. The application was issued on Dec 4, 2024.
Patent Summary
A nail setting device with an electrodynamic drive, comprising a first excitation coil, a soft magnetic frame, and a squirrel-cage rotor that is movably mounted along an axis. The frame has a saturation flux density of at least 1.0 T and an effective specific electrical conductivity of at most 10^6 S/m. The drive is designed for high dynamics, with the rotor and coil arranged to achieve maximum force density during operation. The device further comprises a capacitor arrangement, a switching converter, and an electrochemical energy storage device to power the drive.
