Embodiment Construction

[0072] exist figure 1 A first section of a first preferred embodiment of the electric machine 1 according to the invention is schematically depicted in a sectional view in . The electric machine 1 has a stator 2 with a concavely curved stator inner surface 4 . The stator has a large number of slots 17 which are regularly distributed over the stator 2 . A non-depicted stator winding is arranged at the slots 17 . The outer side of the stator 2 has a cooling jacket 16 for cooling the electric machine 1 . In the first section presented here, the first stator section S1 of the stator 2 is formed. In the first stator section S2 , the stator 2 has a first interruption 6 in the circumferential direction U, which is formed radially over the entire thickness of the stator. The first interruption 6 is approximately 90° in this example. This means that the electric machine 1 does not have the stator 2 in the region of the first interruption 6 . The rotor 3 of the electric machine wi...

Abstract

The invention relates to an electric machine (1) with a stator (2) and a rotor (3) rotatable relative to the stator (2) about an axis of rotation (R), wherein the stator (2) has a concave envelope The stator inner side (4) and the rotor (3) have a rotor outer side (5) with a convex envelope, wherein the stator inner side (4) faces the rotor outer side (5) and is arranged adjacent thereto. The stator (2) has at least one first interruption (6) configured in this way in the peripheral direction (U) of the stator (2) in a first stator section (S1) extending along the axis of rotation (R), Such that the stator inner side (4) of the stator (2) only partially surrounds the rotor outer side (5) of the rotor (3) in the peripheral direction (U) in the first stator section (S1). Furthermore, the invention relates to an electric machine system (13) with a first electric machine (1) and an attachment (14) coupled to the first electric machine (1) in a torque-transmitting manner.

Description

technical field [0001] The invention relates to an electric machine with a stator and a rotor rotatable relative to the stator about an axis of rotation. Furthermore, the invention relates to an electric machine system with a first electric machine and an attachment device coupled to the first electric machine. Background technique [0002] Electric machines are sufficiently known from the prior art and are used in a large number of different technical fields. In automobile construction, electric machines are used, for example, to start and support combustion engines, to drive the motor vehicle and to generate electrical current. Electric machines for drive trains of motor vehicles are mostly designed as rotary electric machines. The widespread design of rotating electric machines has a stationary part (which is also called stator or fixed part) and a movable or rotatable part (which is also called rotor or rotor). Conventional stators have a yoke made of a magnetically c...
