Problems solved by technology

[0005] This proves to be disadvantageous in that an efficient heat transfer from the stator to the coolant flowing through the corresponding cooling ducts is only associated with a considerable structural efficiency
However, this has an adverse effect on the production cost of the motor

Embodiment Construction

[0053] figure 1 An example of an electric machine 1 according to the invention is shown in cross-section. The electric machine 1 is dimensioned such that it can be used in a vehicle, preferably a road vehicle.

[0054] Motor 1 includes only the figure 1 The rotor 3 and the stator 2 are shown in a roughly schematic manner in . For clarity, in figure 2 In a cross-section perpendicular to the axis of rotation D, along figure 1 The section line II-II, shown separately, shows the stator 2 . according to figure 1 , the rotor 3 has a rotor shaft 31 and may have a plurality of magnets which are in figure 1 Not shown in more detail, its magnetic polarization alternates along the circumferential direction U. The rotor 3 is rotatable about an axis of rotation D whose position is determined by a central longitudinal axis M of the rotor shaft 31 . The axis of rotation D defines an axial direction A which extends parallel to the axis of rotation D. As shown in FIG. The radial dire...

Abstract

The invention relates to an electrical machine (1), particularly for a vehicle, comprising a rotor (3) that can be rotated about an axis of rotation (D) defining an axial direction (A) of the electrical machine (1), and a stator (2) comprising a plurality of stator windings (6), with a coolant distributor chamber (4) and a coolant collector chamber (5) axially arranged at a distance from the coolant distributor chamber, the coolant distributor chamber (4) communicating fluidically with the coolant collector chamber (5) by means of at least one cooling channel (10) through which a coolant (K) can flow, the at least one stator winding (6) being embedded, at least in sections, preferably entirely, in at least one plastic mass (11) consisting of an electrically insulating plastic, for thermalcoupling to the coolant (K). The coolant distributor chamber (4) and / or the coolant collector chamber (5) are arranged at least partially in the at least one plastic mass (11), for thermal coupling tothe at least one stator winding (6).

Description

technical field [0001] The invention relates to an electric machine, in particular for a vehicle, and a vehicle comprising the same. Background technique [0002] Such an electric machine can generally be an electric motor or a generator. Motors can be built as external rotors or internal rotors. [0003] A universal motor is known, for example, from US 5,214,325. It comprises a housing that surrounds the inner space and has a sleeve that rotates in the circumferential direction of the housing and radially delimits the inner space; a rear side wall, axially on one side defining an interior space; and a front sidewall axially defining the interior space on the other side. The stator of the motor is fixedly connected to the bushing. The rotor of the electric machine is arranged in the stator, wherein the rotor shaft of the rotor is rotatably supported on the front side wall via the front bearing. [0004] The stator of a conventional electric machine typically includes st...
