  • Patent number: 9356495
    Abstract: A method for soldering a stator of an electric machine to a cooler is described. Firstly, the stator and/or the cooler is coated, at least partially, with a layer of solder. Then, the stator is brought together with the cooler such that the layer of solder is between the stator and the cooler. Finally, the cooler is heated to the melt temperature of the layer of solder in order to produce a solder connection between the stator and the cooler. The cooler can also act as support. Furthermore, a stator for an electric machine, comprising a stator support and a solder connection between the stator and the stator support is described.

  • Patent number: 8115347
    Abstract: The production effort for electrical machines with pole teeth which are fitted with permanent magnets is intended to be reduced. A permanent magnet is inserted between two pole teeth halves (1, 2) for this purpose. The two halves (1, 2) are connected to one another with an interlock by means of a plastic sheath (4). The plastic sheath (4) results in a dimensionally stable pocket (3), in which the permanent magnet can subsequently be inserted. It is therefore possible to insert the permanent magnet as late as possible during the manufacturing process, thus reducing the overall production effort.

  • Patent number: 8076815
    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 (1,2) 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 (3), which connects in each case one end side of the two pole tooth halves (1,2) to one another, is used for forming a pocket (5) between the two pole tooth halves (1,2), 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 (5) relatively late, the entire assembly process can be simplified.

  • Patent number: 8069550
    Abstract: In a method for constructing a linear motor, each tooth of a plurality of teeth is provided with two separate tooth halves with removable tooth tips. After removing the tooth tips to expose an open end of the tooth halves, a prewound coil is pushed over the open end of the two tooth halves of each tooth up to an end position, and a magnet is inserted between the two tooth halves of each tooth. The tooth halves have a thickness between the open end and the end position which does not exceed a thickness of the tooth halves at the end position.
