Abstract

Rotational thermal generator of the proposed design converts mechanical rotational motion into thermal energy. The installation operates on the basis of induced currents generated by changing magnetic field. Electric currents induced by changing magnetic field are also referred to as “Foucault currents”.  Magnets are fixed to a moving unit – a rotor that rotates by virtue of an axis with bearings. Magnetic field generated by permanent magnets is closed by a ferromagnetic stator. The motion induces currents in the ferromagnetic stator. The induced currents heat the stator. Thus, the energy of mechanical rotation motion is converted into thermal energy.  Stator can be homogeneous or constructed using several metals, such as copper and steel, aluminium and steel, or other structural compound of low resistance metals with ferromagnetic materials. As the stator is heated, it transfers the heat to a heat exchanger made of fins and attached to the stator. Heated stator and heat exchanger emit heat into the surrounding medium, thus transferring it into air or other gas.

This invention relates to electric machines and generators.

State of the art

The closest analog of the present invention is the technical solution described in WO2011140320 (A2) - 2011-11-10

The proposed embodiment provides a method of generating heat by using permanent magnets whose rotating magnetic field generates inductive currents in the metal, or in a structural metal compound which heats said metal or structural metal compound.

In the description, we do not find any structural solutions for transferring the incoming heat to air or liquids. The only phrase found is that the resulting heat can heat air, liquids, sodium. Specifies the possibility of heating but not providing technical solutions for transferring the resulting heat to heat carriers: Air, liquids, gas.

The essence of the invention

The rotary motion heat generator of the presented construction converts mechanical rotary motion into thermal energy. the operation of the device is based on inductive currents generated by an alternating magnetic field. Inductive currents caused by an alternating magnetic field are also known as "Fuko currents".

The magnets are mounted on a moving part - a rotor that has the ability to rotate - thanks to an axle with bearings. The magnetic field created by the permanent magnets closes in the ferromagnetic stator. During motion, inductive currents are generated in the ferromagnetic stator. The resulting induction currents heat the stator. In this way, the energy of the mechanical rotational motion is converted into thermal energy.

The stator can be homogeneous or made of different metals - copper and steel, aluminum and steel or other low-resistivity metal compound with ferromagnetic materials. The stator heats the heat to a plate-shaped radiator attached to it. A heating stator with radiator releases heat to the environment. In this way the heat is transferred to air or other gases.

This is shown in Figure 4. A variant of a rotary motion heat generator for heating liquids is shown in Figure 5 and Figure 6.

Description of Embodiment of the Invention

The advantage of the presented construction is that it is simple to manufacture, does not require special materials, does not require special equipment for production.

The outer steel member of the rotor must be manufactured in such a thickness that the magnetic field of the magnets closes without creating additional magnetic impedance. The rotor has the ability to rotate.

During operation, inductive currents are generated in the stator during rotation of the rotor. Because each material has its own specific electrical resistance, the material heats up under current. Flowing inductive currents heat the stator. The stator transfers heat to the environment.

The working conditions of the generator are defined by the efficiency of the cooling medium and the circulation. The power of the generator is determined by the permissible operating temperature of the magnets, the strength of the magnets, the amount of magnets, the rotational speed of the rotor and the coercive magnetic field generated by the induction currents.
