Definitions
- the invention relates to an electric motor having a rotor comprising a rotor shaft and a rotor body, and a stator having a stator laminated core with a plurality of stator laminations and at least one integrated bearing seat for receiving a bearing in which the rotor shaft is rotatably mounted , as well as methods for mounting such an electric motor.
- the invention is particularly suitable, for example, for use in motor vehicles.
- electric motors which are designed as small engines, play an important role due to the limited space.
- Small motors are electric motors with small dimensions and usually have a power up to 1 kW.
- Electric motors can be designed as internal rotor or external rotor motors.
- Internal rotor motors have a fixed stator and an inner rotating rotor.
- the rotor is coaxial, concentrically inserted into the stator.
- the rotor concentrically surrounds the stator.
- electric motors typically include a housing that protects the engine from external influences such as dirt or moisture.
- the rotor or the rotor shaft must be rotatably supported by bearings.
- the bearing of the rotor shaft is realized for example with one or more complex end shields.
- stator has integrated bearing seats for receiving bearings in which the Rotorwelie is rotatably mounted.
- a brushless DC motor comprising a shaft, a permanent magnet rotor and a stator with a plurality of pole shoes provided with windings, wherein two shells of non-magnetic material are provided, each having a bearing for the shaft and brackets for the Have pole pieces.
- the invention has the object of providing an electric motor of the type mentioned in such a way that it is compact and as small as possible. Furthermore, it should be easy and inexpensive to manufacture.
- the electric motor has a rotor comprising a rotor shaft and a rotor body, and a stator having a stator laminated core with a plurality of stator laminations and at least one integrated bearing seat for receiving a bearing in which the rotor shaft is rotatably mounted. Since the bearing is stressed by different forces, it makes sense to strengthen the bearing seat.
- at least one end-side stator plate of the stator laminated core is designed such that it has means for reinforcing the bearing seat.
- the means for reinforcement are designed as reinforcing anchors and arranged on the inner diameter of the end-side stator lamination.
- the reinforcing anchors and the end-side stator plate are integrally formed.
- stator laminations of the stator laminar packet have at least one side a lacquer layer, for example a baked enamel layer, and are connected to one another in a materially bonded manner by a chemical-thermal connection.
- the coated stator laminations are first joined together to form a so-called stator laminations.
- the stator lamination stack is heated briefly, whereby the lacquer layer, in particular the baked enamel layer, is made to melt and thus the stator laminations are firmly bonded together chemically-thermally.
- stator laminated core In order to be able to provide windings to the stator laminated core, the stator laminated core, in particular the pole teeth of the stator core pack, must be electrically insulated.
- the stator laminated core is preferably encapsulated with a plastic.
- the bearing seat on the stator is formed during the encapsulation of the Stator Bleckpers.
- the reinforcing anchors are angled before the encapsulation of the stator-Bleckpers and the injection of the bearing seat, in the direction in which the injection-molded bearing seat is located.
- the Reinforcement anchor angled 90 °. After manufacturing the bearing seat, the bearing is pressed into the bearing seat.
- the bearing can be placed in an injection mold and the bearing seat is practically "sprayed around" around the bearing in the injection mold during the encapsulation of the stator Bleckpers.
- Fig. 1 shows an embodiment of the stator of the invention
- FIG. 2 shows an embodiment of the end-side stator lamination of the electric motor according to the invention in a plan view
- Fig. 3 is a partial view of an electric motor according to the invention in one
- Fig. 1 shows an embodiment of a stator of the electric motor according to the invention in a perspective view.
- the stator 1 consists of a stator laminated core 2 with a plurality of stator laminations.
- the stator plate 3 on the end face of the stator laminated core 2 is designed such that it has means for reinforcing the bearing seat, not shown.
- the means for reinforcement are designed as reinforcing anchors 4 and arranged on the inner diameter 5 of the end-side stator 3.
- the reinforcing anchors 4 and the end-side stator 3 are integrally formed. It can be seen particularly well that the reinforcing anchors 4 are angled before the extrusion of the stator laminated core 2, in the direction in which later, the injection molded bearing seat, not shown, is located. In essence, the reinforcing anchors 4 are angled by 90 °.
- the pole teeth 6 of the stator lamination Pact 2 can be seen, which are provided with windings, not shown.
- the end-side stator 3 has the reinforcing anchors 4 for reinforcing the bearing seat, not shown.
- the reinforcing anchors 4 are arranged on the inner diameter 5 of the end-side stator lamination 3. It can be seen particularly well that the reinforcing anchors 4 and the end-side stator plate 3 are integrally formed. In Fig. 2, the reinforcing anchors are not angled. Furthermore, the pole teeth 6 of the stator lamination Pact 2 can be seen, which are provided with windings, not shown.
- Fig. 3 shows a partial view of an electric motor according to the invention in a longitudinal sectional view.
- the electric motor 10 has a rotor comprising a rotor shaft 12 and a rotor body 11, and a stator comprising a stator laminated core 2 having a plurality of stator laminations 7 and an integrated bearing seat 13 for accommodating the bearing 14 in which the rotor shaft 12 is rotatable is stored, has. Since the bearing 14 is stressed by various forces, it makes sense to reinforce the bearing seat 13.
- the end-side stator 3 has means for reinforcing the bearing seat 13.
- the reinforcing means are designed as reinforcing anchors 4 and arranged on the inner diameter 5 of the end-side stator 3.
- the stator laminations 7 have at least one side of a paint layer, not shown, and are materially interconnected by a chemical-thermal connection.
- the stator laminated core 2 In order to be able to provide the stator laminated core 2 with windings not shown, the stator laminated core 2, in particular the non-visible pole teeth 6, must be electrically insulated.
- the stator laminated core 2 is preferably encapsulated with plastic, whereby the encapsulation 15 is formed.
- the bearing seat 13 is formed during the encapsulation process of the stator laminated core 2. Before the extrusion coating of the stator laminated core 2 and the injection of the bearing seat 13, the reinforcing anchors 4 are angled, in the direction in which the injection-molded bearing seat 13 is located. In essence, the reinforcing anchors 4 are angled by 90 °. After production of the bearing seat 13, the bearing 14 is pressed into the bearing seat 13.
