Definitions
- Stator device with interconnected end plate for an electric motor and use of the stator device
- the present invention relates to a stator for an electric motor according to the preamble of the main claim. Furthermore, the present invention relates to a use of such a stator device.
- stator devices are well known; these have an angle carrier on or on which a plurality of stator windings wound with suitable angle wire are seated. Depending on the realization principle of the electric motor realized with such a stator device, these windings are connected or connected in a suitable manner; For example, it is known as a typical use of such a generic stator device to set up and to connect the stator device with the windings provided thereon for generating a rotating electrical field, which in turn can be connected to a suitable rotor rotatably mounted about the central axis (as external rotor or rotor) Inner rotor) cooperates.
- a typical implementation of a stator device for generating a three-phase rotating field for realizing a three-phase motor requires the connection of the windings in star connection (Y-circuit), alternatively in a delta connection, again alternatively in mixed forms of these generic circuit topologies, in particular also several, typically in Circumferentially arranged circumferentially offset from each other of the windings in a typical three-phase system can be connected in parallel to each other.
- the free wire ends typically realized with the winding connections
- are led out separately and interconnectably arranged windings are connected via connection or connection arrangements in order to achieve the desired topology and, for example, Effecting parallel circuits to ensure a correct operating power supply of the overall arrangement.
- stator devices having a larger number of individual windings, approximately twelve or more individually contactable windings on a winding support are not uncommon, but then an electrotechnically and mechanically complex connection structure arises, which not only, for instance for mechanized or automated purposes Production, is complicated to produce, but also space-related disadvantages and disadvantages in terms of failure and failure endangered operating environments has.
- connection or carrier body voluminous, difficult in automated handling, especially in the actual (non-detachable) producing an electrical contact and not unproblematic in the fixation in the context of a respective motor to be assigned housing structure;
- the present invention is therefore based on the object of further improving an upper conceptual stator device for an electric motor with regard to mounting and manufacturability and in terms of higher product quality.
- annular deflecting disk is provided on the interconnected end disk, on the inside of which deflecting pegs which are arranged distributed circumferentially and distributed for deflecting the winding wire are integrally formed.
- stator arrangement has therefore been supplemented according to the invention by a separate deflecting disk, which bears concentrically against the interconnected end disk at its side facing away from the winding carrier.
- the deflecting pins arranged distributed circumferentially on the inside of the deflecting disk allow the winding wire to be deflected in such a way that it can be guided precisely through an opening of the welding hooks without a high winding tension.
- the resulting strain relief of the winding wire and the mechanical relief of the welds on the welding hooks represent a further advantage with regard to increased manufacturing quality.
- the locking rings are stacked in the interconnected end disk such that the winding terminals of a winding guided at least in sections parallel to the central axis and / or without crossover in each case have a welding hook formed radially on the inside of two of the locking rings to reach.
- the present invention combines high reliability with simple and reliable manufacturability, since the radially inboard welding hooks with automation tools, such as a welding gun, can be achieved.
- the number of contact connections to be produced is only determined by the number of windings which, in the preferred application, are simply configurable on the winding support and either by suitable design of a respective winding carrier, alternatively by only partial or suitable winding of a winding carrier with the desired number of windings, suitable for a particular purpose.
- the deflecting pins in the axial direction and are axially aligned on the interstices of the welding hooks aligning bar, so that the winding wire on the deflection pin is feasible.
- winding wires can thus advantageously be guided with strain relief over the deflecting pins and without crossovers parallel to the respective welding hooks of the locking rings and are contacted at the welding hooks so that the contact reliability is ensured in every configuration with simple manufacturability.
- the locking rings are designed as punched parts and the switching end plate is designed as an injection-molded component with overmolded Verschaltringen.
- the design of the Verschaltetringe as stamped parts simplifies their manufacturing process and allows their easy integration by reprecipitate, so that the boarding end plate with the embedded United shell rings can be produced as a compact injection molded part in large quantities kos ten officer.
- the three stamped parts of the faceplate can be used as identical parts and underline a cost-optimized approach.
- the integrally formed on the Verschaltringen welding hooks axially adjacent Verschaltetringe along a circumferential direction are arranged offset and / or jump offset.
- the arrangement of the welding hooks of the Verschalttringe so that along the circumferential direction, these welding hooks are offset from each other.
- Such an arrangement especially when used with a plurality of, for example, twelve or more windings, reduces the risk of unintentional contact between winding wires of different phases and, in addition, simplifies automated contacting, for example by the intervention of welding tongs.
- the result of the present invention is a stator device which is suitable for any use, phase and pole numbers and number of turns, but in particular with more than six, preferably more than nine or even more than twelve windings considerable advantages in the beginning has described problem context.
- the present invention is suitable for applications in automotive or manufacturing technology, where often mechanical or thermal stressing environmental conditions can be expected, but the invention is not limited to this application context and application.
- the present invention is in principle independent of a realization of the stator device according to the invention for a Rotorrealisie- tion as internal or external rotor.
- FIG. 1 shows a circuit diagram for clarifying the interconnection of the windings in the exemplary embodiment of FIG. 3 as a triangular circuit with four parallel windings each;
- FIG. 2 shows a connection and winding diagram for the windings according to FIG. 1;
- FIG. 3 is a perspective view of a stator device according to a first preferred embodiment of the present invention in a 12-pole configuration for an internal rotor;
- Fig. 4 is a perspective view of a Verschaltrings with molded
- Fig. 5 is a perspective view of a stacked arrangement of three
- Fig. 6 is a perspective view of the interconnected end plate with integated, encapsulated Verschaltringen and Fig. 7 is a perspective view of the deflection plate.
- FIG. 1 and FIG. 2 illustrate in a circuit diagram that the windings 1 'to 12' are supplied with a three-phase rotating field with the phases (terminal polarities) U, V, W, wherein in FIG. 1 or FIG In each case, four of the windings 1 'to 12' form a branch of the delta connection shown in parallel and are nested along the circumferential direction of a winding support 4 (FIG. 3) according to their numbering in the circumferential direction.
