Embodiment Construction

[0049] Figure 1A An exemplary embodiment of a stator 1 in an electric machine configured as a rotary electric machine with an internal rotor is shown in a perspective illustration. To provide a good overview, the rotor is not in Figure 1A drawn in. On the inner side, the electric machine comprises a stator extending axially along a peripheral slot 2 into which in each case one conductor part 3 of the stator winding is inserted. Here, exactly one conductor part 3 is arranged in each slot 2 .

[0050] Figure 1B The stator winding is shown with parallel running conductor parts 3 without stator sheet metal encapsulation in order to provide better visibility of the winding structure. It can be seen that in this embodiment the conductor parts 3 are configured straight, have a rectangular cross-section and are distributed along the periphery of the electric machine. The conductor parts 3 have the same length and are oriented parallel to the motor shaft. The conductor parts 3...

Abstract

The invention relates to a power supply unit for supplying multiple conductor portions (3) of a stator winding of an electric machine which are inserted in respective slots (2), wherein the power supply unit is configured to supply a first conductor portion and a second conductor portion with at least one different operating parameter of a respective current function and / or the power supply unit is configured to supply a conductor portion with at least two superimposed current functions, which in each case have at least one different operating parameter. Furthermore, the invention relates to an electric machine having such a power supply unit.

Description

technical field [0001] The invention relates to a power supply unit for supplying conductor parts of a stator winding of an electric machine and an electric machine with the power supply unit. Background technique [0002] The stator of the electric machine usually includes electrical windings connected to the power system, which in turn often has a multi-phase configuration. [0003] Distributed windings are often used in applications with more than two coils per phase per pole. Such distributed windings have many disadvantages, such as increased manufacturing expenditure caused by superimposition of coils. [0004] However, the main advantage of distributed windings lies in the fact that the magnetomotive force in the air gap between the stator and the rotor of the electric machine movably supported relative to the stator has a smaller part of the harmonics, i.e. a smaller amount of the magnetomotive force undesired harmonics of . This results in a higher performance mo...
