Electric motor or generator with permanent magnets

Abstract

The invention was based on the task of converting the magnetic force of powerful permanent magnets for effective energy generation in electric motors or generators. This has been achieved with the invention. In conventional electric motors or generators the magnetic pole fields are generated by electric coils. These require electricity. When permanent magnets are used the electricity requirement is eliminated. The electric motor or generator has the dimensions of a flat circular disk with purpose-made diameters. In terms of construction the electric motor or generator has a stator ring with a U-shaped cross-section in which permanent magnets are inserted opposite one another. In the stator ring between the pole fields NS of the magnets there is a rotor ring which is firmly connected to the hub or shaft by a disk or spoke construction.The rotor ring contains radial channels for the conductors, which are arranged at equal spacing around the circumference. The stator ring and the rotor ring are made of a magnetic transformer material. The arrangement of the magnetic transformers ensures an effective flow of the magnetic force field. The magnetic transformers of the stator ring and rotor ring are either prefabricated from a cast body or assembled from magnetic transformer sheets. The flat design of the electric motor or generator allows for the staggering of several units on a single shaft. The construction of the electric motor or generator exhibits a large magnetic force field in which many conductors with a long total length, through which current flows, produce a powerful deflection movement or lead to a high induced voltage at high speed. The rotor is lightweight, which reduces centrifugal forces and improves performance. The use of identical components saves production time and costs.The design and functionality of the electric motor or generator with permanent magnets provides high energy output with high efficiency, demonstrates cost-effective and rapid production, offers versatile economic use and makes an effective contribution to energy demand.

[0003] This task was conceived on the basis of the invention, with the construction and the function, the features listed in claims 1 to 4.

[0004] The following disclosure documents were researched: DE 10 2021 210 220 A1 2022.03.17, DE 10 2018 006 915 A1 2020.03.05, DE 10 2013 206 572 A1 2014. 10. 16, DE 2018 133 002 A1 2020.06.25, DE 10 2019 132 832 A1 2020.06.10, DE 10 2013 206 572A1 2014.10.16

[0005] The listed publications do not have any essential comparable features of the invention in terms of design and function.

[0006] Construction of an electric motor or generator. The design of the electric motor or generator resembles a flat circular disk.

[0007] Several circular segments (12) which have a U-shaped cross-section in which permanent magnets (13) are inserted opposite one another and are made of a magnetic transmitter material form a stator ring (11).

[0008] In the stator ring (11) between the pole fields N - S of the permanent magnets (13), separated by air gaps (20), there is a rotor ring (14) which is composed of circular segments and consists of a magnetic transformer material.

[0009] In the rotor ring (14) channels (17) for the current conductors are provided in the radial direction and at equal intervals around the circumference.

[0010] The rotor ring (14) is connected to the rotor shaft, hub (19) by a spoke construction (18) or a circular disc construction.

[0011] The rotor ring (14) is enclosed with tires (15) (16) which statically reinforce the rotor ring, form a current bridge to the current conductors in the channels (17) and are used as a receiving flange for a spoke construction (18) or a circular disc construction.

[0012] The rotor of the electric motor or generator has a low weight, which reduces centrifugal forces and promotes performance.

[0013] The electric motor and generator can be mounted and used multiple times on one shaft.

[0014] An effective flow of the magnetic fields is achieved by the arrangement of the U-shaped magnetic field transmitters (12) with incorporated permanent magnets (13), the rotor ring (14) as a magnetic field transmitter, with internal current conductor channels (17).

[0015] In conventional electric motors and generators, the magnetic pole fields are generated by electric coils. In electric motors or generators with permanent magnets, the magnetic fields are already present.

[0016] The electric motor or generator with permanent magnets demonstrates, due to its construction and mode of operation, a good energy output with a high degree of efficiency and is versatile, economically applicable and implementable.
