Embodiment Construction

[0026] figure 1 An electric machine 10 designed as a claw-pole generator is shown in cross section, more precisely a cross section of an electric machine 10 which, in the embodiment shown here, is embodied as a motor vehicle for converting mechanical energy into electrical energy claw pole generator. The electric machine 10 has a two-part housing 13 comprising a first bearing shield 13.1 and a second bearing shield 13.2. The bearing caps 13.1, 13.2 themselves accommodate the so-called stator 16, which consists of a substantially circular stator core 17 and is inserted or embedded in its radially inwardly oriented, axially extending grooves ( prominent) stator winding 18. The annular stator 16 surrounds with its radially inwardly directed surface a rotor 20 , which is designed as a claw pole rotor (not shown in detail here). The rotor 20 includes claw poles 22 and counter poles 23 (see also figure 2 ), they are also called claw pole plates, and claw pole fingers 24 and 25 ...

Abstract

The invention relates to a method for manufacturing and / or driving a motor (10). The motor, especially, is an electric generator, such a claw pole electric generator, and / or a starting device, such a starter used for driving an internal combustion engine. The motor (10) provides a rotor (20) equipped with at least a winding bundle (51) arranged between poles (22 and 23). At least part of the winding bundle (51) is insulated by an insulation device (100) relative to the poles (22 and 23). The voltage difference is balanced by utilization of at least a conductive guiding device (110) to minimize generation of a parasitic electric field. The guiding device (110) is arranged in and / or on the insulated insulation device (100). The invention relates to a motor used for carrying out the device of the method.

Description

technical field [0001] The invention relates to a method for producing and / or operating an electric machine, in particular a generator such as a claw-pole generator and / or a starting device such as a starter for driving an internal combustion engine. [0002] Furthermore, the invention relates to an electric machine, in particular a generator such as a claw pole generator and / or a starting device such as a starter for driving an internal combustion engine. Background technique [0003] The invention is based on an electric machine for converting mechanical energy into electrical energy or vice versa. [0004] The subject matter of the invention is an electric machine, in particular a claw-pole generator, for supplying a direct voltage from a vehicle electrical circuit to a motor vehicle. [0005] A generator for converting mechanical energy into electrical energy in a motor vehicle is known from the prior art. Claw pole generators are mostly used for this purpose. Typical...
