Description

A system for assisting wind turbine operation and an electromagnetic engine.
The invention relates to a system for assisting wind turbine operation.
From patent P-415826 description there is known a synchronous, multi-segment generator having multiple rotor disks with permanent magnets mounted on a main shaft and multiple stator segments with a phase winding which are placed between the rotor disks, wherein the stator segments are mounted on threaded detachable pins attached to a base and to a lid and which are placed coaxially to the main shaft around a circle bigger than the diameter of the rotor disks and whereby the stator segments are kept in place with nuts.
From patent P406415 description there is also known a multi-segment wind turbine consisting of separate turbines-segments having a vertical axis bearing-mounted rotor placed in a casing created by rotors between which there are mounted air guides.
According to the invention at least one rotor disk on its surface which faces a closest base has permanent magnets mounted on a circular path which runs, favourably, on the edge of the rotor. At least one of the bases, which acts as a stator, on its surface facing said rotor has coils located on a circular ring having width and radius corresponding to the circular path of the permanent magnets. The angular arrangement of the magnets differs from the angular arrangement of the coils, which are connected via a controller with a DC power source. When angular position of any of the permanent magnets overlaps with angular position of any of the coils, the current powering the coil is cut off. Favourably, distances between the coils are uniform and the arrangement of the magnets is cyclic, which means that the position of at least every third magnet overlaps with the position of a coil.
And, alternately, the distances between the permanent magnets are uniform, whereas the arrangement of the coils is cyclic, which means that the angular position of at least every third coil overlaps with the position of a permanent magnet. Favourably, the permanent magnets are positioned on two or more circular paths and, correspondingly, the coils are positioned on two or more circular rings that are situated in the same manner. Because the rotors are equipped with permanent magnets and because the coils are powered, it gives possibility for RPM adjustment so that expected output is achieved when wind velocity is low. There is a possibility to adjust the rotating speed of the turbine. An added value of the electromagnetic power is achieved. A practical example of the invention is shown on figures, whereby fig. 1 shows a wind turbine with its rotor partially exposed, fig. 2 shows the wind turbine with the rotor, having two assisting systems, partially exposed from two sides, fig. 3 a diagram showing the arrangement of the permanent magnets and the coils, fig. 4 a cross-section of the rotor, fig. 5 a half view of the plate of the rotor housing with two circular paths of the coils, fig. 6 a half view of the rotor disk with two circular paths of the permanent magnets.
A rotor 1 of a wind turbine comprises two discs 2 connected with an axle 3, whereby between the discs 2 there are blades 4. The axle 3 is supported by bearings in circular plates 5 of a housing. Between the plates 5 there are guides 6 mounted. On the bottom disc 2 facing the plate 5 there are 18 permanent magnets 7 positioned in an evenly spaced manner along a circular ring 8 located at the edge of the disc 2. On the surface of the circular plate 5 there are 24 coils 9 which are positioned in an evenly spaced manner along a circular ring 10 which in orthogonal projection overlaps with the circular ring 8. The angular distance between the permanent magnets 7 is 20°, whereas the coils 9 are located every 15°. The coils 9 are connected to a DC power source via a controller 11. Every coil whose position overlaps with the position of one of the permanent magnets 7 is not being powered.
An example of the arrangement of the permanent magnets 7 and the coils 9 on the circular path does not exclude many other variants of their configuration. A crucial prerequisite is that the spacing of the permanent magnets 7 has to differ from that of the coils 9. The example of the arrangement does not exclude a variant wherein the angular spacing between the coils will be greater than that between the permanent magnets 7. It is favourable that the spacing both between permanent magnets 7 as well as between the coils 9 is even. It is possible that both on the disk 2 and on the plate 5 there are more rings with the permanent magnets 7 and corresponding number of rings with the coils 9. On fig. 6 there is shown one half of the disk 2 with the permanent magnets 7 positioned on two circular rings 8 and 12, and fig. 5 presents one half of the plate 5 with the coils 9 also positioned on two circular rings 10 and 13.
The system for assisting wind turbine operation might be used when wind force is weak and the rotor revolutions too slow to generate expected power. By connecting power source to the coils 9 the electromagnetic field is generated which by interacting with the magnetic field of the permanent magnets 7 generates force attracting the magnets and thus the rotor 1 of the turbine. The closer one of the permanent magnets 7 is in relation to one of the coils 9, the greater becomes the attraction force until the permanent magnet reaches the position of the coil 9. In this moment, or a little bit earlier, the controller 11 powers off the coil. This firstly considered permanent magnet 7 thanks to forces of inertia moves on further away from the coil 9. Then the controller 11 switches the power back on until another of the permanent magnets 7 reaches the position convergent with the position of the coil 9.
Favourably, after the permanent magnet 7 moves away from the coil 9 the controller 11 switches the power back on with reverse polarity which exerts a momentary repelling force on the first permanent magnet 7. When the next permanent magnet comes as close towards the coil 9 as is approximately the distance from the coil 9 of the outgoing first permanent magnet 7, the controller 11 reverses polarity of the current powering this particular coil 9. Operations of such kind take place in the same way with all the remaining coils 9 thanks to synchronisation of power supply for every one of the coils 9 or their groups.
Synchronising controls of the second assistance system installed on the second disc 2 of the rotor 1 operates in a similar way to the system described above. Power control is executed by changing voltage of the current powering the coils 9.
The second invention relates to an electromagnetic motor. In case of this motor the principle solution consists in that the angular spacing in radial direction of permanent magnets on a rotor disk mounted on an axle is different compared to the spacing of coils. The winding of all the coils is connected via a controller with a power source, wherein every coil whose angular position overlaps with an angular position of one of the permanent magnets is powered off.
Favourably, the distances between the coils are even, whereas the positioning of the magnets is cyclical, which means that the position of at least every third permanent magnet overlaps with the position of the coil.
Alternately, radial distances between the permanent magnets are even, whereas the positioning of the coils is cyclical, which means that the angular position of at least every third coil overlaps with the position of the permanent magnet. Favourably, the permanent magnets are arranged on two or more circular paths and, correspondingly, the coils are arranged on two or more circular rings.
Favourably, there is more than one group of both coils and of permanent magnets mounted on the axle.
The motor is characterised by small dimensions and a simple design. Possible applications of the motor are manifold; it can be used with many different machines and devices. It is characterised by a quiet operation. The practical example of the invention is shown on the diagram, wherein Fig. 7 presents an axial section of the motor.
The housing of the motor comprises two circular plates 15 and a shield 16 screwed on the circumference of the plates 15. Additionally, the plates 15 are screwed down with screws 17. In the plates 15 there is an axle 18 supported by bearings and having discs 19 mounted on it. On the discs there are permanent magnets 7 fitted in such a manner that they are positioned evenly along the perimeter of the disc 19 on a circular ring placed on the outer part of the surface of the disk 19. In parallel to the surface of the disc 19 with permanent magnets 7 there is a circular plate 20 mounted on the screws 17 and positioned with spacers 21. On the surface of the circular plate 20 there are coils 9 fitted which are positioned evenly on a ring sector like the above mentioned circular ring on the surface of the disc 19, whereby there are 36 coils 9 along the circumference, while the number of the permanent magnets is 48. The coils 9 are powered with direct current via a controller 22. When the angular position of the permanent magnets 7 overlaps with the angular position of the coils 9, then the coils 9 are temporarily powered off.
Starting of the motor happens after the coils 9 are powered on, which generates electromagnetic field, which generates force attracting the permanent magnets 7. After one of the permanent magnets 7, the one closest to the coil 9, reaches the position facing this coil 9, the controller 11 powers this coil 9 off. This firstly considered permanent magnet 7 thanks to the inertia forces of the rotor 1 moves on away from the coil 9. When the next permanent magnet 7 comes as close towards the coil 9 as is the distance from the coil 9 from the outgoing first permanent magnet 7, then the controller 11 powers the coil 9 back on until the next permanent magnet 7 reaches the position convergent with the position of the coil 9.
