Abstract

The previously known electromagnetic rotation motors are distinguished by a relatively large power consumption, rapid exhaustion of the electrical energy from the sources, and high construction and yield costs because of the large weight of the batteries required. These defects are overcome according to the invention by up to 50% in that round permanent magnets 2 having gearwheels 3 (which are mounted on them and are placed freely on shafts 4 which are mounted in the housing 1) are accommodated in the housing 1, on its circumference. Accommodated centrally in between the permanent magnets 2 is a permanent magnet 5 which is coupled to all the permanent magnets 2 by the gearwheels 6. Accommodated between the permanent magnets 2, on the circumference, are electromagnets 7 which are connected to an electronic control system. The central magnet 5 having the gearwheel 6 is placed on a driveshaft 8 which is passed to the exterior of the housing 1. This design makes it possible for a state of unstable balance to exist between all constant magnetic fields, which unstable balance is disturbed when the current is switched on in a continuous manner. This flowing current is approximately 50% lower because it is necessary only to generate a supplementary magnetic field. <IMAGE>

Description

Magnetic Rotary Cor

The invention relates to a direct current fed magnetic Rotary motor with electronically controlled rotating fields, which is used to drive various in rotary motion drives z. B. from tape recorder drive to vehicle drive is provided.

In known and previously used to drive mechanical transmissions electromagnetic rotary motors powered by accumulators or batteries are generated, the electromagnetic excited between the stator and rotor Fields that are used to generate movement through electric current, which flows in the winding of the stator or the rotor or both elements at the same time.

The drawbacks of this solution are a large power requirement, a relative one rapid exhaustion of the electrical energy from the sources, as well as the limitation the possible applications in many areas of mechanics. aside from that are the construction and exploitation costs of these engines because of the great weight of the batteries needed high.

The invention is based on the object of a magnetic rotary motor to train in such a way that it largely eliminates the shortcomings mentioned and one in relation to the known solutions approx. 50% longer use of the electric Current source allows, if the other comparable parameters are observed.

This object is achieved according to the invention by what is stated in the characterizing part of the claim 1 detected features solved.

Round permanent magnets are attached to a housing on its circumference housed them attached gears, which freely attached to in the housing Axes are put on.

A round permanent magnet is housed in the middle of these permanent magnets, which is coupled to all permanent magnets on the circumference by means of gears.

Between all of these magnets there are electromagnets that are connected to an electronic control system. The central magnet is placed on a drive shaft which is led to the outside of the housing.

The construction according to the invention offers a number of essential advantages.

The construction of the engine is simple and its assembly is easy.

It does not contain any wearing contact pieces such as sliders and commutator rings, which transmit the supply to the rotor.

The heat generated in the windings of the electromagnets is several times less than in the windings of the traditional solution, whereby the ratio of the power to the mass of the magnet motor is greater.

The working principle of the magnetic rotary motor according to the invention allows the rotation speed to be changed easily. This change can be made at optimal construction conditions are 1:50.

Another advantage is that the engine put into operation partially releases the electrical energy to the power source again.

Another advantage is that the connected electronic sch Control system a regulated multiphase generator of pulses with constants or variable filling factors of the impulses, which are designed to be executed as Integrated circuit or hybrid circuit is suitable, which is low in series production Manufacturing costs guaranteed.

The subject matter of the invention is based on an exemplary embodiment the description and the drawing explained in more detail, wherein: Fig. 1 - the magnetic Rotary motor in cross section Fig. 2 - the rotary motor in vertical section FIG. 3 - the block diagram of the electronic control system of FIG. 4 - the generator pulse diagram, Fig. 5 - the group pulse diagram, which represent controlling the electric switch.

In the housing 1, round permanent magnets 2 are attached to them on its circumference mounted gears 3 housed. The permanent magnets 2 with the gears 3 are freely placed on the axes 4 attached to the housing wall 1. Midst the permanent magnet 2 is centrally housed a round, roller-like permanent magnet 5, which is coupled to all permanent magnets 2 by the gears 6. In the case 1 on the circumference between the permanent magnets 2 electromagnets 7 are housed. Of the Central permanent magnet 5 with the gear 6 is placed on the drive shaft 8, the is guided to the outside of the housing 1.

On the rear housing wall 1 is the bound electrical niche Control system 9, which is covered with the lid 10. This system has contact pieces 11, 12, which are used to connect to the supply and the speed controller 13.

The electronic control system 9 includes one provided by the speed controller 13 regulated circuit of the generator of pulses 14 with constant or variable Fill factors of the impulses. In addition, the control system 9 contains the circle of Phase generator 15 for generating the group pulses 16, which the electron switch 17 to which the winding of the electromagnet 7 is connected. The electric switch 17 are secured against overvoltage by diodes 18, the electromagnets 7 by Diodes 19.

The system of round permanent magnets 2 and the round central permanent magnet 5 has a parallel to the axis of these magnets dividing line of the magnetic poles. This Magnets are coupled together by the gears 3 and 6 in such a way that between All constant magnetic fields are in a state of unstable equilibrium. Each permanent magnet 2 is turned backwards by the angle ß compared to the previous one, which by dividing the full angle by the number of permanent magnets 2 is calculated. One pole of the permanent magnet 5 is small in the rotating direction Angle shifted and has the same sign as the pole of the closest to it Permanent magnets 2.

The effect of the magnetic rotary motor according to the invention is the following.

After switching on the supply, the electronic one closes Control system 9 the electromagnets 7 on. It flows through them in a pulse-like manner one after the other electric current and creates an additional magnetic field all around, which disturbs the state of equilibrium and the rotation of the permanent magnets 2 and 5 causes the following unstable positions.

This type of switching causes a magnetic to develop Field, which in a continuous manner the subsequent states of equilibrium disturbs.

This flowing current is around 50% less than in traditional solutions, because it only creates a complementary magnetic field. In addition, the electronic effects Power of induction of the not switched on in the corresponding phase of the movement Electromagnet 7 the excitation in them of a current, which is partly the source returns.

The whirling of the round permanent magnets 2, 5 and the gears 3 6 supports the work of the motor and adds to the energy generated in the motor kinetic rotational energy and thereby compensates for the running of the engine.

The moments that occur on the rays of the individual elements The forces between the names of the same name and those of different names add up directly Magnetic poles occur, add up as in the geometric progression of the quadratic function.
