Embodiment Construction

[0057] Figure 1a A stator 1 of an electric motor is shown in a perspective view as a device for driving a compressor of gaseous fluid for conveying refrigerant through a refrigerant circuit, which compressor is used exclusively in motor vehicle air conditioning systems. The stator 1 is shown in a perspective representation with a stator core 2 and a cover element 3 which is arranged on a first end face of the stator 1 and is fitted with a mounting element 4 for mounting a plug-in connector. Figure 1b and Figure 1c are detailed views of the first end face of the stator 1 with coils 5 arranged on the stator core 2 and without cover elements, each shown in a perspective view, while Figure 1d Shown in cross-section with cover element 3 Figure 1a Detail of stator 1 in .

[0058] An electric motor, eg an AC motor with three phases, has a rotor, not shown, and a stator core 2, which is arranged in radial direction on the outer surface of the rotor and thus surrounds the rotor. ...

Abstract

The invention relates to a device for driving a compressor, in particular an electric motor, having a rotor and a stator (1) with a stator core (2), which are arranged along a longitudinal axis (7), and a method for producing the device. The stator (1) has: a connecting cable (8a) and a connecting line (8b) arranged on a first end face of the stator (1), the connecting cable being formed as a plurality of sections of a conductor (8) of the coil (5); an insulating element (6), the wall of which is formed substantially in the shape of a hollow cylinder and protrudes beyond the stator core (2) on a first end face of the stator (1) in the axial direction; and a cover element (3) having a mounting element (4) with connecting channels for mounting the plug-in connector (9), each of which is completely enclosed by a free wall (4a). The connecting cable (8a) or the connecting line (8b) is arranged on the wall of the insulating element (6) in the circumferential direction. The cover element (3) is in contact with a first end face of the stator (1) on the stator core (2) in the axial direction and covers a wall of the insulating element (6) protruding beyond the stator core (2). The volume enclosed by the walls of the stator core (2), the cover element (3) and the insulating element (6) protruding beyond the stator core (2) is at least partially filled with a potting compound (12).

Description

technical field [0001] The present invention relates to a device, in particular an electric motor, for driving a compressor for compressing a gaseous fluid, in particular a coolant. Compressors may be used in refrigerant circuits of motor vehicle air conditioning systems. The device has a rotor and a stator extending along a common longitudinal axis. The stator has connecting cables and connecting lines formed as sections of wire of the coil. Background technique [0002] Compressors known from the prior art for mobile applications, in particular for motor vehicle air conditioning systems and for conveying refrigerant through a refrigerant circuit, also known as refrigerant compressors, usually form It is a piston or scroll compressor with variable displacement. The compressor is driven by a pulley or electrically. [0003] The electrically driven compressor has an inverter for driving the electric motor in addition to the electric motor for driving the appropriate compr...
