Embodiment Construction

[0017] In order to achieve the above object, the present invention provides an AFPM coreless compound generator, which includes: a rotor fixedly mounted on a rotating shaft to rotate with the rotating shaft, and the rotor is provided with a magnet; and a stator fixedly mounted to the side housing and having a coil disposed therein.

[0018] Wherein, the coil included in the stator is arranged between the upper clamping plate and the lower clamping plate made of non-magnetic material, and the space between the upper clamping plate and the lower clamping plate where the coil is installed is filled with cooling insulating oil, The cooling insulating oil is sealed by two side plates, one of which is fixedly connected to the casing of the generator to allow heat conduction to the casing. In this case, the space between the upper clamping plate and the lower clamping plate where the coil is installed may also be filled with an inert gas instead of cooling insulating oil.

Abstract

The present invention relates to an axial flux permanent magnet (AFPM) coreless multi-generator and motor. The present invention is characterized in that the stator includes coils arranged between upper and lower jig plates made of a non-magnetic material, cooling insulating oil is filled in a space where the coils are mounted between the upper and lower jig plates and is sealed by both lateral plates, and one of the both lateral plates is fixedly coupled to the housing of the generator so as to allow the housing to perform thermal conduction. Also, the rotor includes magnets arranged on a rotor disc in a circular arc shape and a yoke element formed integrally with the rotor disc near a central portion thereof in such a fashion as to vertically protrude by a predetermined height. The rotor disc is fixedly mounted to the rotary shaft, and the yoke element is engaged with a yoke element of another rotor correspondingly adjacent to the rotor so as to allow the engaged yoke elements to serve as a passageway of a magnetic field. The rotor and stator are configured in a multi- structure. The present invention can be applied to a motor having the same structure as that of the generator.

Description

technical field [0001] The present invention relates to an axial flux permanent magnet (hereinafter referred to as AFPM) coreless multi-generator (multi-generator) and a multi-motor (multi-motor), more particularly, relates to an AFPM coreless multi-generator and In this AFPM coreless compound generator and compound motor, the heat generated by the coil is conducted to the stator plate by using cooling insulating oil, and the heat of the stator plate is conducted to the case, thereby dissipating the multi-rotor (multi- rotor) and multi-stator (multi-stator) structure of the heat. Background technique [0002] Typically, an electrical generator comprises a rotor having a plurality of magnets arranged on a rotor disc and fixedly mounted to a rotating shaft, and a stator mounted spaced from A coil is provided on the disk, and the coil induces a voltage through the magnetic flux generated by the rotation of the rotor, and the stator is fixedly mounted on the side housing. The ...
