Abstract
Electrical machines having pole teeth which can be equipped with a permanent magnet are intended to be capable of being assembled more easily. Provision is made for this purpose for two pole tooth halves () to be provided for each pole tooth, each of which two pole tooth halves has two opposing end sides. At least one end-side plate (), which connects in each case one end side of the two pole tooth halves () to one another, is used for forming a pocket () between the two pole tooth halves (), into which pocket a permanent magnet can be inserted. A space for the permanent magnet can therefore be kept free during assembly of the pole tooth or during winding thereof. Since the permanent magnet only needs to be inserted into the pocket () relatively late, the entire assembly process can be simplified.
