Electric tool for e.g. router, has power generation arrangement with rotation axle, and induction coil producing magnetic field of magnet, where distance of coil corresponds to distance of magnet for axle of magnet

摘要

The tool has a power generation arrangement that includes a rotation axle. An induction coil produces a magnetic field of a magnet (105). The distance of the coil corresponds to the distance of the magnet for the rotation axle of the magnet. Lines of flux of the magnet run partly parallel to the rotation axle. The magnet is in the form of a ring, and has multiple bar magnets.
