Description

The field of technology

The technical solution falls into the field of electric motors and generators. It is a kind of rotating electric machine, in which the rotating motion of the rotor separated by an air gap from the stator causes the conversion of electrical energy into mechanical, rotary motion or linear motion through the energy of the electromagnetic field. Structurally, they are electric motors, dynamos, generators or alternators very similar. Electric motors also work as generators, so they can be used as an electrodynamic brake.

Current state of the art

An electric motor is an electrical machine that converts electrical energy into mechanical energy through the interaction of magnetic fields and current-carrying conductors. Electric motors use the mutual force action of the magnetic field and electric current through the coil. This physical phenomenon is called electromagnetism, but there are also motors based on other electromechanical phenomena, such as electrostatics or the piezoelectric phenomenon. The basic principle of electromagnetism is the mutual force action of electromagnetic fields created by electric conductors through which an electric current flows or the action of these fields with the magnetic field of a permanent magnet. The electric motor and generator consists of two parts, the stator - the static non-moving part and the rotor - the moving part. In a conventional rotary motor, the rotor is positioned so that the magnetic field created in the rotor conductors and the magnetic field of the stator develop a torque transmitted to the rotor of the electric motor. In an electric motor or generator, the rotating part of the rotor is usually located inside the stator, evenly surrounded by the stator winding, or a permanent magnet.

The essence of the technical solution

The essence of the technical solution defined in the claims for the protection of this utility model is an electric motor or generator based on a new architecture and, in particular, an improved system and method for generating rotary motion from an electromagnetic motor or for generating electrical energy from the input of rotary motion. Various embodiments of the motor or generator are described, including methods and systems for increasing flux density by manipulation of permanent magnets. It is about achieving the lowest possible weight with the highest possible performance. As energy becomes more scarce and expensive, more efficient electric motors and generators are needed to reduce energy consumption and therefore costs. The presented electric motor solutions aim to reduce mechanical losses, reduce electricity consumption and emissions, improve torque, save material and reduce the weight of the electric motor or generator, improve energy security, and reduce the harmful impact on the environment due to the use of energy sources. Electric motors and generators are lighter than traditional, classic electric motors and generators, the construction of which includes several combinations. The essence of this solution is the versatile use of coil and magnet. An electric motor or generator uses radial upper, radial lower and also axial flows. It is a construction of an electric motor or generator consisting of a multi-sided coil mounted in the stator, where the rotor has a different construction and surrounds the stator from several sides and thus uses radial upper flux, radial lower flux and also axial right flux and axial left flux. Electromagnets or sidewall magnets also contribute to the magnetic field, thus also creating flux forces. In an electric motor or generator, the direction of the magnetic flux is kept parallel to the axis of rotation, both radially and axially. An electric motor can be used in several ways: as a DC motor, permanent magnet motor, electromagnet motor, series motor, derivative motor, series-parallel motor, AC motor, synchronous or asynchronous motor, single-phase or three-phase motor. Improving the design of an electric motor or generator consists in increasing the density of the electromagnetic flux as well as the density of the flux with permanent magnets, which results in an increase in the rotational and torque from the electric motor and, in the case of the generator, increased generation of electrical energy from the input of rotary motion. The electric motor or generator has a larger diameter because the stator, composed of a multi-sided coil, is placed in the center of the rotor. The electric motor or generator can be cooled by air or liquid. The essence of this solution is the multiple use of the coil installed in the stator.
