Embodiment Construction

[0073] Before describing the proposed principle in detail with reference to a specific embodiment example, first the basic principle based on only one coil level or only one coil with a different number of turns will be described.

[0074] figure 1 An example embodiment of a stator using a shear diagram in cross-section is shown. For example purposes, the motors are configured as linear motors. The coils of the first phase winding A of the electrical winding are placed in the first groove 1 and in the second groove 2 . The coil of the phase winding A has a first number of turns n1 in the first groove 1 and the same coil has a second number of turns n2 in the second groove 2 . The other coil of the first phase winding A is located in the first groove 1 and in the third groove 3 drawn to the left thereof. The additional coil likewise has a number of turns n1 in the first groove 1 , whereas it has a second number of turns n2 in the third groove.

Abstract

The invention relates to an electric machine comprising a stator (8) and a rotor (9). The stator comprises grooves (1, 2) for receiving at least two coils of an electric winding. The first coil comprises a first winding number (n1) in a first groove and a second winding number (n2) in a second groove (2). The second coil comprises a first winding number (n1′) in a first groove and a second winding number (n2′) in a second groove (2).

Description

technical field [0001] The invention relates to an electric machine. Background technique [0002] Electric machines generally include a stator fixed with respect to a housing and a rotor movable relative to the stator. The rotor may be rotatably positioned relative to the stator or may be moved linearly relative to the stator. Electric machines are classified under electromechanical energy converters. Here, they can be operated as electric motors or generators. [0003] For example, an electric machine can be used to drive an electric motor vehicle. Here and in other applications, it may be advantageous to achieve certain characteristics in the operating behavior of the electric machine. These properties may include torque, acoustic properties, core losses as well as winding losses and magnet losses. [0004] The stator of a motor with concentrated winding differs from the stator of a motor with distributed winding by the compact design. Different numbers of pole pair...
