The most promising are gearless motor-wheel in which the wheel is called directly by the electromagnetic interaction of the magnetic systems of the rotor and stator. Known built-in motor (WO 93/08999 A1, 13.05.93), contains two main parts: a stationary stator, mounted on an axis and having a magnetic circuit with permanent magnets placed evenly; and the movable rotor bearing ring and containing at least two groups of electromagnets, and a distribution manifold mounted on the stator and having a conductive plate connected to the constant current source. The rotor is fixed to the current collector with an electrical contact with the plates of the discharge header.

The specified motor-wheel is the meet various modifications and variants (US 6384496 B1, 07.05.2002; US 6617746 B1, 09.09.2003; EN 2129965 C1, 10.05.1999; EN 2172261 C1, 20.08.2001).

Combining the main elements of the motor-wheel, in combination with additional devices, allows you to create similar in principle of operation and possessing the stated advantages of the motor-wheel.

However, the described motor-wheel and its variants have several disadvantages, the main of which is the need of large inrush and transient currents during starting and acceleration of the vehicle. This leads to rapid wear and deterioration of the battery and the deterioration of thermal regime. Another disadvantage is the lack of an effective return and use of electricity. Also these motors have low torque, which significantly limits their practical use.

Known technical solutions aimed at eliminating these disadvantages associated with the use of high-voltage power sources and complex control schemes, which makes them expensive and unreliable in operation (US 6791226 B1, 14.09.2004; US 6727668 B1, 27.04.2004; US 6355996 B1, 12.03.2002).

The present invention is directed to reducing the cost of the motor, increasing its efficiency, elimination of sparking and reactivity, creating conditions for the free inertial stroke and high speed rotation of the electric motor while maintaining relative simplicity of construction and reliability.

Induction motor, made in accordance with the present invention, contains:

- rim, which is the same step are teeth made of magnetic material;

circular frame, bearing an even number of u-shaped (U-shaped) of electromagnets arranged in pairs opposite each other and having two coils sequentially counter voltage is the making of a winding;

- means for supplying to the coils of the electrical impulses of the same polarity.

The number of teeth on the rim is equal to n, satisfy the following relations:

Preferably, the number of electromagnets located on a circular frame, satisfy the relation: m=4+2L, where L is any integer satisfying the condition of 0≤L≤k. The most commonly used ratio of the number of teeth and the magnets of the following: n=10, m=8; n=14, m=6; n=18, m=8; n=22, m=10, etc. of the Winding coils of adjacent electromagnets are connected in series, and the conclusions are the opposite windings of the electromagnets, is not connected to the means for supplying electrical pulses are connected to each other.

The ratio of the number of electromagnets and teeth of soft magnetic material, their relative positions and used circuit switching electromagnets provides the resonance currents flowing through the windings of diametrically opposed electromagnets, and, consequently, reduces power surges (power consumption) when starting and acceleration of the motor and improves its dynamic characteristics.

In the present invention can be used also any other scheme of connection of the windings of the electromagnets that meet the above conditions and to achieve the home is built result.

Induction motor, in accordance with the present invention, can be accomplished in two ways.

In the first variant, the role of money supply to the electromagnets of electrical impulses performs collector. In this case referred to the rim with teeth made of magnetic material, is located on the stator of the motor. The rotor separated from the stator by an air gap, contains a circular frame, bearing an even number of u-shaped electromagnets arranged in pairs opposite each other. The collector is fixed to the stator, is located on the insulating base, the conductive plates separated by dielectric gaps. Conductive plate connected to one pole of the DC source. The other pole of the DC source connected to the motor housing.

The motor also includes a current collector that is installed with the possibility of contact with the plates of the collector. Each of the current collectors are connected to the same conclusions: or only at the beginning of each winding, or only at the end of each obmoroki of the respective electromagnets. Conclusions opposite windings of the electromagnets, is not connected to the current collector, closed on the case.

The total number of the conductive plates of the collector is equal to the number of stator teeth. When this axis l of the Institute of dielectric gaps collector oriented along the axial lines of stator teeth. Design execution collector can be end or radial.

In another embodiment of the invention induction motor made in accordance with the brushless scheme. In this case, the motor contains:

a stator with a circular frame, bearing an even number of u-shaped (U-shaped) of electromagnets arranged in pairs opposite each other and having two coils sequentially counter-winding direction;

the rotor separated from the stator by an air gap, the rotor is rim with teeth made of magnetic material;

- electronic control system voltage, which generates pulses of direct current;

the sensor of angular position of the rotor, which sends a signal to the electronic circuit for zapisywania or de-energizing the coils of the electromagnets when passing by them of the rotor teeth.

When brushless embodiment of the induction motor design of electromagnets and how they are switching similar to that described above.

Position sensor rotor (DPR) implements feedback on the position of the rotor, it performs the same function as the collector in the DC motor. His work can be based on different physical principles: photoelectric, inductive, Hall effect, etc. of the Greatest pop lampost acquired the Hall sensors and photoelectric, since they are practically businessone and allow to get rid of lag in the feedback channel.

The control system contains power switches, often thyristors or power transistors with insulated gate. Of them is going pulse voltage generator. The sensor signals are converted control device in combination of control voltages that control the power switches so that in each cycle of motor operation is enabled, the corresponding electromagnets. The key management system is typically implemented through the use of a microcontroller.

Instead of an electronic circuit and a sensor of angular position of the rotor for the timely filing and removing power from the stator electromagnets can be used filed on feedback information about the counter EMF and RISC microcontroller, or any other way to achieve the stated result.

Structurally, both the electric motor can be made so that the rotor will be located on the outer side of the stator or the rotor is located inside the stator.

The absence in the design of the motor permanent magnets reduces the final cost, eliminates the reactivity and arcing creates conditions for the free inertial stroke and high speed rotation.

The invention is illustrated by the following drawings:

figure 1 shows a diagram of the electric motor, made in accordance with the present invention, in which the stator is located outside of the rotor;

figure 2 shows the electrical circuit of the motor;

figure 3 shows the diagram of the electric motor, made in accordance with the present invention, in which the stator of the motor is located inside the rotor;

figure 4 shows a diagram of a brushless motor, made in accordance with the present invention, in which the stator is located inside the rotor.

Figure 1 presents the electric motor, made in accordance with the present invention, which can be used as an electric drive in various fields of science and technology. The motor includes a shell 1, in the role of a protective casing. The stator 2 of the motor is located outside of the rotor 3. The stator 2 has a circular frame 4, which is an even number of teeth 5 of magnetic material with the same step. In this case, fourteen teeth. The teeth can be a metal plate (made separately from mild steel, such as the brand A)secured in the slots of the stator 2. Or, as in this case, the entire stator with teeth recruited from the laminated plates (made, e.g. the, electrical 2412). The rotor 3 is separated from the stator by an air gap and is an even number of magnets 6. In this case, six. The electromagnets are arranged in pairs opposite each other and form three pairs. Each of these magnets has two coils 7 with consistently counter-winding direction (i.e., if one of the coils is wound clockwise, the other counter - clockwise). Between one coil of the electromagnet are connected in series, the first end of the winding coil of the electromagnet is connected to the start winding of the second coil of the electromagnet. In figure 1 the beginning of the winding of the first coil is marked with the letter "H", the end of the winding of the second coil is marked with the letter "K".

When the motor coil 7 of the electromagnets 6 are powered from a DC source (not shown) through a distribution manifold 8 and the current collector 9. Distribution manifold 8 is stationary relative to the stator, and the current collector 9 are connected with the rotor as it rotates move relative to the conductive plate 10. These conductive plate connected to the positive pole of the DC source and separated by dielectric gaps 11. The number of conductive plates in the manifold corresponds to the number of teeth of the stator and in this case equals fourteen

Each of the current collector 9 is connected to the same conclusions one of the windings of the electromagnets 6. 1 shows a connection option to the beginning of the winding of the first coil of the electromagnet, indicated by the letter "H". (Alternatively connecting the current collector to the end of the winding of the second coil, designated by the letter "K", in this case the motor will rotate in the same direction.) The direction of rotation of the motor is determined by the firing angle between the current collector and the conductive plates of the collector.

Between the electromagnets 6 are connected according to the following scheme:

winding coils of adjacent electromagnets are connected in series, i.e. the output winding "To" one electromagnet is connected with the output "H" of adjacent electromagnet; and the conclusions are the opposite windings of the electromagnets, is not connected to the current collector, in this case, "K", are connected together and shorted to the frame.

The total number of teeth on the stator - n, equal to fourteen, and the number of electromagnets - m, is equal to six, satisfy the relations:

n=10+4k

m=4+2L, where k=L=1.

The principle of operation of the motor, made in accordance with the present invention, based on electromagnetic forces of attraction arising from the interaction of the magnets 6 of the rotor and the teeth 5 of the stator. After passing electromagneto the provisions when its axis is located between the axes of the teeth, through the current collector feeds the coil of the electromagnet, thus, the electromagnet is attracted to the next spike. When passing through the electromagnet position opposite the axis of the tooth it is de-energized, since the current collector is located opposite the dielectric gap. It is the position of the electromagnet passes through the "thrust" of other phases, geometrically shifted relative to each other.

Distribution manifold 8 is connected to the source 13 DC (Figure 2). The key 14 provides total turn-off. In addition, the electrical circuit may include additional blocks (not shown) to stabilize and control the electric current. For example, for acceleration and hill start assist can be used to drive Emotron having a pulse discharge high capacity and high reliability.

The number of turns in the windings of the coils opposite electromagnets may be different. To enhance resonance phenomena preferably, this difference was size 1/2^pof the total number of turns in one coil, where p=2, 3, 4, 5, etc. for Example, if the total number of turns in the coils of the same electromagnet is 128 and p=5, then the total number of turns in the coils diametrically opposite the electromagnet will be 124. If p=4, the total number of turns in the coils diametrically opposite electromagnet is equal to 120 and so on

Figure 3 presents the electric motor, made in accordance with the present invention, which can be used as the motor-wheel for different vehicles, such as scooters with electric bike or electric car. The motor includes a shell 14, fulfilling the role of a protective cover and directly transmitting the rotation of the wheel. Shell is connected by spokes to the wheel rim (not shown). The stator 15 of the electric motor is located inside the rotor 16. The stator 15 has a circular frame 17 on which the same step is an even number of teeth 18. In this case, fourteen teeth. The rotor 16 is separated from the stator by an air gap and is an even number of electromagnets 19. In this case, six. When the motor coils of the electromagnets 19 are powered from a DC source (not shown) through manifold 20 and the current collector 21. The collector 20 is stationary relative to the stator, and the current collector 21 is connected with the rotor as it rotates move relative to the conductive plates 22.

The design and principle of operation of this motor is similar to that described above.

Figure 4 presents brushless motor in accordance with another variant of the present invention. The motor contains a shell 23, issue is Manaudou the role of the protective casing. The stator 24 of the electric motor is located outside of the rotor 25. The stator 24 with the same step is an even number of electromagnets 26. In this case, six electromagnets. The electromagnets are arranged in pairs opposite each other and form three pairs (phase). The rotor 25 is separated from the stator by an air gap and is an even number of teeth 27. In this case 14. Structurally, the execution of the electromagnets and their switching similar to that described above. The motor also includes a sensor 29 of the angular position of the rotor, which sends a signal to the electronic circuit 28 for zapisywania or de-energizing the coils of the electromagnets 26 while passing past them teeth 27 of the rotor.
