SUBSTANCE: invention relates to electric drives of carriers, said, scoters, bikes, electric vehicles, helicopters and aircraft. Proposed invention consists in adding extra internal magnetic core with teeth on vehicle drive motor stator body in case said motor is used as an inductor motor. In case external magnetic core with teeth is composed by inductor composed by permanent magnets, extra inner inductor with permanent magnets is fitted therein. Application of permanent magnets as the stator inner and outer inductors is required to ensure higher torque.
EFFECT: decreased consumption of electric power, higher torque.
The invention relates to the field of electrical engineering and can be used as electric vehicles.
The technical result achieved by the present invention is to reduce the cost of the drive, increasing the efficiency of energy supply of the drive.
Known technical solutions aimed at creating electric vehicles. One of them is electric vehicles, representing an induction motor (patent RU No. 2340994 C1).
Induction motor according to this invention contains a rim, on which the same step are teeth made of soft-magnetic material, a circular frame, bearing an even number of u-shaped electromagnets arranged in pairs opposite each other, having two coils in series-opposing direction of the windings, and means for supplying to the coils of the electrical impulses of the same polarity.
The disadvantage of this induction motor is inefficient use of electrical energy supply device (battery).
This induction motor device consuming electrical energy are electromagnetic coils, which have ferromagnet the s cores are U-shaped. All magnets have two poles. With this construction, the electromagnetic coils in cooperation with the teeth of the external magnetic circuit of the stator participate magnetic flows only those poles that are directed toward them through the air gap. Magnetic poles of the same electromagnetic coils facing in the opposite direction, in the interaction do not participate, but simply pass through the yoke of the U-shaped ferromagnetic core.
The proposed design of the electric drive ensures the participation in the interaction between the magnetic fluxes of both poles of the solenoid coils with teeth or permanent magnet stator.
In the induction motor, patent RU No. 2340994, changing the design of the blocks of paired electromagnetic coils and installing optional internal magnetic core with teeth or permanent magnets, we will get the electric machine as an electric drive vehicle with a higher torque for the same power consumption, or when the same torque is smaller the energy consumption, i.e. will increase mileage on a single charge of the battery. This effect is possible because the work includes another magnetic flux, equal to an already running.
If you need to have more torque on the shaft of the vehicle, for example the EP rotor helicopter, instead of the magnetic circuits of Mahamantra material, you must install the permanent magnets. The operation of the proposed electric vehicles can be made using a mechanical brush-collector device, and using existing electronic devices, rotor position sensors, such as Hall sensor.
The number of teeth in additional internal magnetic core of the stator or the number of permanent magnets must be equal to the number of teeth in the external magnetic circuit of the stator or the number of permanent magnets.
The technical result is achieved by the fact that in the known electric drive vehicles containing the stator magnetic circuit with teeth made of a ferromagnetic material, the rotor carrying the electromagnetic coil arranged in pairs opposite each other, a manifold mounted on the stator housing, the current collector according to the invention, the stator has an additional internal magnetic core with teeth or additional internal inductor consisting of permanent magnets in the case if, instead of an external magnetic circuit with the teeth on the stator has a coil consisting of permanent magnets. Moreover, ferromagnetic cores for electromagnetic coils have a linear shape, fixed gesture is about, in pairs, parallel to each other in the shelf brackets are made of non-magnetic, dielectric material so that the ends of the linear ferromagnetic cores that serve as the poles of the solenoid coils, turned with an air gap to the teeth cores or poles of the permanent magnets of the stator inductors, if they are used instead of magnetic circuits with teeth.

- Bracket block electromagnetic coils 6;
- Brush collector 7;
Electromagnetic coil 8;
- Drive shaft (axle) of the vehicle 9.
- Ring for installation internal magneto the gadfly with teeth or inductor with permanent magnets 10.
The operation of electric drive vehicles is as follows.
Electric current from the power supply (battery) is supplied to the reservoir 2. In any position of some collector plates are always in contact with the brushes of the current collector 7. The electric current for this circuit is supplied to the electromagnetic coil 8 connected at this point to the electrical circuit. Occurred at the poles of the electromagnetic coils pulses of magnetic fluxes interact with the teeth of the outer and inner cores of the stator or the poles of the permanent magnets of the outer and inner coils of the stator. Set the process of "pull" when using cores with the teeth and the process of " attraction-repulsion" when using permanent magnets. This results in a torque, there is a movement of the brushes on the collector plates. Next, the switching of solenoid coils and, consequently, begins a steady rotation of the rotor.
The principle of operation of the actuator according to the invention is based on the forces of attraction-repulsion pulsed electromagnetic flow electromagnetic poles of the coils of the rotor teeth of the outer and inner cores of the stator or poles of the permanent magnets of the external and internal Indus is tori stator, used instead of magnetic circuits with teeth.
