Embodiment Construction

[0023] The electrical equipment constituting the generator shown in FIGS. 1 to 3 relates to a unit consisting of a drive motor and a synchronous generator. A diesel engine is preferably considered as the drive engine, for which only the end of the crankshaft 1 connected to the synchronous generator is shown in dotted lines in the figure. The fan impeller 2 is connected with the bolt 3 at the end of the crankshaft 1 . The fan wheel 2 has a set of blades for generating a motor-cooling airflow as indicated by the arrow S1 , wherein the air flowing according to the arrow S2 corresponds to the cold air flowing out of the generator housing 8 after cooling the generator. As shown in FIG. 1 , the generator housing end cover 9 on the power output side has intake openings for the flow of cooling air according to arrow L. As shown in FIG. In order for this cooling air flow to achieve its sufficient cooling effect within the generator housing 8 , the protective cover 14 has one or more (...

Abstract

The invention relates to a generator set composed of a generator and a piston internal combustion engine as a driving device, especially a generator set composed of a synchronous generator and a diesel engine. It includes a generator rotor for generator excitation located in the magnetic pole area. The permanent magnets in the generator and the armature windings (28) in the stator. In this generator set, a mounting slot (34) with at least one side open in the axial direction is formed in the magnetic pole area of ​​the rotor (29), which passes through a cylindrical shape. The circumferential wall (50) is adjacent to the air gap (33) formed between the rotor and the stator (11); the permanent magnet in the magnetic pole area is composed of multiple magnet elements (35), which are arranged side by side in the mounting slot along the circumferential direction. (34) Inside.

Description

technical field [0001] The invention relates to a generating set consisting of a generator and a piston internal combustion engine as a driving device, in particular a generating set consisting of a synchronous generator and a diesel engine, which is included in the generator rotor for the excitation of the generator and is arranged in the magnetic pole area permanent magnets and armature windings in the stator. Background technique [0002] Such a generator set combined with a pump set is described in DE 19721527 . [0003] Permanent magnet motors typically have permanent magnets that are constructed from one piece per pole. In the known generator, each permanent magnet has the shape of a cylindrical shell segment, which adjoins the air gap formed with the stator in the region of the poles. [0004] Such permanent magnet housings are nearly impossible to manufacture economically and are certainly not sized for generators of power over 5kVA. The assembly of such integral ...
