Electrical Machine with an Insertion Device for a Permanent Magnet Between Pole Tooth Halves and Corresponding Production Method

摘要

The manufacturing effort for producing electrical machines with pole teeth which are fitted with permanent magnets is intended to be simplified. The permanent magnets are inserted into the pole teeth only at the end of the manufacturing process, for this purpose, with the pole teeth each comprising two pole teeth halves ( 1, 2 ). An insertion device ( 3 ) which may be in the form of a frame is arranged between the pole teeth halves ( 1, 2 ). The insertion device ( 3 ) is used to keep a space free for the individual permanent magnets during the assembly process. By way of example, this allows the pole teeth to be wound without permanent magnets interfering with this manufacturing step. Permanent magnets are finally inserted into the insertion devices.
