Technical task

In a conventional engine, each permanent magnet and the coil are single stage. Thus, the engine must be large to provide sufficient output power. If the engine has a small volume, the engine provides a very small magnetomotive force and, thus, develops a small torque. Thus, a vehicle equipped with this engine, can't give you high the same power, and the problem arises, namely that it is difficult to reduce the weight of the vehicle.

The figure 7 presents a side view in section of another embodiment of the motor having a magnetic circuit, arranged concentrically, according to the present invention.

The engine, shown in figure 7, includes a fixed shaft 210, the rotor 220 and stator 240, as shown in figure 1.

The rotor 220 includes a magnetic circuit 221 and 223, magnets 225, 227 and 229 and the rotating disk 231. In the engine shown in figure 7, there are connecting holes 236 for attachment to the brake disk 255, which will be described below, and these holes are made in one surface of the rotating disk 231 and differ from the engine shown in figure 1.

However, in the engine shown in figure 7, the fixed disk 251 and the fixed shaft 210 is formed as a one piece unit.

The figure 10 presents a side view in section of another embodiment of the motor having a magnetic circuit, arranged concentrically, according to the present invention, and figure 11 shows a front view in section of the engine shown in figure 10.

Engine 360, shown in figure 10, contains a fixed shaft 310, the rotor 320 and the stator 340.

The rotor 320 is the magnetic circuits 321 and 323 of the rotating disk 331 and magnets 325, 327 and 329. In the engine shown in figure 7, the magnetic circuit 223 are removable connected to the other surface of the rotating disk 231. However, in the engine shown in figure 10, the cores 321 and 323 are formed by extending one surface of a rotating disk 331. Thus, the cores 321 and 323 made in one piece with the rotating disk 331. When the magnetic circuit 223 and the rotating disk 231 are manufactured separately and assembled together, as in the engine shown is ω in figure 7, may be error in the Assembly. As a result, taking into account errors in the Assembly, the engine is designed so that a sufficient gap between the magnetic circuit 223 and the metal cores 241 and 243 anchors. However, with increasing gaps between the magnets 225, 227 and 229 and coils 245, 247 and 249 power output of the engine is reduced. In the engine shown in figure 10, all the cores 321 and 323 are formed in one piece with the rotating disk 331. Thus, because there is no build error, it is possible to accurately reduce the gaps between the cores 321 and 323 and the metal cores 341, 343 anchors. Thus, the engine shown in figure 10, has a higher capacity compared with the engine, are shown in figure 7.

Figure 14 shows another example embodiment of the engine according to the present invention. In the example embodiment shown in figure 10, the cylindrical cores 321 and 323 are formed by extending one surface of a rotating disk 331. The magnetic circuit must be made of iron, to determine the flux lines. Thus, in the case of the example embodiment shown in figure 10, since the rotating disk 331 and cylindrical cores 321 and 323 are formed as one unit, they are all made of iron. In this case, the engine has a lot of weight. However, in vopl is not the same, shown in figure 14, the cylindrical magnetic circuits 421 and 423 are inserted and fixed on one surface of the rotating disk 431. Thus, the cylindrical magnetic circuits 421 and 423 and the rotating disk 431 are formed separately. In this case, the cylindrical magnetic circuits 421 and 423 are made of cast iron, and the rotating disk 431 is made of aluminum or similar material to reduce the weight of the engine. In addition, for more reliable installation of the first magnetic circuit 421, the cylinder housing 432 is formed, extending peripheral surface of a rotating disk 431 to surround the first magnetic circuit 421. The cylindrical magnetic circuits 421 and 423 are formed of cast iron or similar material. In addition, after installation of the cylindrical magnetic circuits 421 and 423, rotating disk 431 and the cylinder housing 432 are formed from aluminum by way of injection molding or similar process. In the result, it is possible to reduce the weight of the engine.

The example embodiment shown in figure 15, further includes a rim 455 extending from the outer peripheral surface of the cylindrical body 462, compared to the example embodiment shown in figure 14. Thus, in the example embodiment shown in figure 15, the brace can b shall be directly installed on the outer peripheral surface of the engine.

Below will be described a drive device having a motor, according to another variant of the present invention.

The figure 3 shows the front view in section of the device of the drive, using the example of an embodiment of the engine shown in figure 1, and shown in figures 3 and 4 examples of the incarnation.

If the rotor 20 of the motor 60 mounted on the rim 61 of the brace 63, as shown in figure 3 and 4, it can be used as a device actuator of the vehicle, another vehicle or motorcycle. Thus, if power is supplied to the coil 45, 47 and 49 of the anchor, brace 63 is rotated due to the rotation of the rotor 20, and if the brake disc 55 is pressed, using the support plate 57, the rotor 20 is stopped.

The figure 8 shows a side view in section of the device of the drive, using the example of an embodiment of the engine shown in figures 7 and shown in figure 9 as a front view in section of the example embodiment shown in figure 8.
