Description

Closed electromagnetic field magnetic spot motor

Technical Field

The invention relates to an electric machine, in particular a magnetic spot electric machine with a closed electromagnetic field.

Background

The existing various brushless direct current motors are not really direct current motors, the input current of the direct current motors is direct current, the direct current motors are unstable, the internal magneto-electric operation process and the operation principle of the brush direct current motors and the brushless direct current motors are alternating current electromagnetic fields, so that the so-called direct current motors still have iron loss and copper loss which are inevitably present in a transformer, and the brush direct current motors and the brushless direct current motors have great energy loss and serious heat generation when rotating at high speed due to the iron loss and the copper loss, so that the brush direct current motors and the brushless direct current motors are difficult to operate at ultra-high speed. All motors and direct current motors are developed according to Faraday armatures, and the working principle of a direct current generator is that alternating electromotive force induced in an armature coil is changed into direct current electromotive force by matching a commutator with the reversing action of an electric brush. Brushless motors are produced by exchanging the stator and rotor of a conventional dc motor. The rotor generates air gap flux for the permanent magnet: the stator is an armature and consists of multiphase windings. The stator of brushless motor has the same structure as that of common synchronous motor or induction motor, and has multiphase windings embedded inside the iron core. The rotor is mainly made of rare earth materials with high coercivity and high remanence, such as samarium cobalt or neodymium iron boron, and the like, and can be divided into surface magnetic poles, embedded magnetic poles and annular magnetic poles due to different positions of the magnetic materials in the magnetic poles. Since the motor body is a permanent magnet motor, a brushless motor is also called a permanent magnet brushless dc motor in a conventional manner. The 2 copper brushes or carbon brushes of the brush motor are fixed on the motor rear cover through an insulating seat to directly introduce the positive electrode and the negative electrode of a power supply to a phase changer of a rotor, the phase changer is communicated with coils on the rotor, and the polarities of the 3 coils are continuously and alternately changed to form acting force with 2 magnets fixed on the shell to rotate. Because the commutator is fixed with the rotor and the brush is fixed with the housing (stator), the brush and the commutator continuously rub to generate a great deal of resistance and heat when the motor rotates. The inefficiency and loss of the brushed motor is very large. But it also has the advantages of simple manufacture and low cost.

Because the armature loop resistance and inductance of the motor are small, and the rotator has certain mechanical inertia, the armature rotating speed and corresponding back electromotive force are small in the starting stage when the motor is powered on, and the starting current is large. The maximum value can be 15-20 times of rated current. This current can cause disturbances in the grid, mechanical shocks to the machine, and sparks to the commutator. Therefore, the direct closing starting is only suitable for motors with power not more than 4 kilowatts (the starting current is 6-8 times of the rated current), in order to limit the starting current, a specially designed variable resistor is usually connected in series in an armature circuit, and the direct closing starting is widely applied to various small and medium-sized direct current motors. However, the method is not suitable for a motor which is started frequently and a medium-sized and large-sized direct current motor because of large energy consumption in the starting process. However, for some special needs, such as frequent starting of urban electric vehicles, a series resistance starting method is generally adopted in order to simplify equipment, reduce weight and facilitate operation and maintenance. For a dc motor having a large capacity, a step-down voltage is generally used for starting. The armature of the motor is supplied by an independent voltage-adjustable direct current power supply, and the voltage of the power supply is controlled to enable the motor to start smoothly and realize speed regulation. This approach is relatively complex in power supply equipment.

In the control structure of the brushless motor, the brushless motor is one type of synchronous motor, that is, the rotation speed of the motor rotor is affected by the speed of the rotating magnetic field of the motor stator and the number of poles (P) of the rotor, and n=120.f/P. Under the condition that the number of poles of the rotor is the same, the rotating speed of the rotor can be changed by changing the frequency of the rotating magnetic field of the stator. The brushless motor is a mode of adding an electronic control (driver) to the synchronous motor, controlling the frequency of a stator rotating magnetic field, and feeding back the rotating speed of a motor rotor to a control center for repeated correction so as to achieve the characteristic approaching to the direct current motor. That is, the brushless motor can control the motor rotor to maintain a certain rotation speed when the load changes within the rated load range.

Switched reluctance motors are ac motors in which the reluctance of the magnetic circuit varies as much as possible as the rotor rotates. Therefore, the stator and the rotor of the motor are both in double-salient pole structures and are formed by stacking silicon steel sheets. A simple concentrated winding is arranged on each stator magnetic pole, and the windings on two diametrically opposite stator magnetic poles are connected in series or in parallel to form a phase. There are no windings on the rotor, nor permanent magnets. The motor can be divided into an odd phase and an even phase according to the number of phases of the motor. The motor can be divided into a bipolar long magnetic circuit structure and a four-pole short magnetic circuit structure according to the magnetic circuit structure of the motor. According to the energizing pattern of the motor, there are single-phase excitation and multi-phase excitation,

The coil of the hollow cup motor looks like a water cup, so that the hollow cup motor is used as a direct current motor, the structural structure of the rotor of the traditional motor is broken through, the weight and the moment of inertia of the rotor are greatly reduced, and the mechanical energy loss of the rotor is reduced. The running characteristic of the motor is improved due to the structural change of the rotor, so that the motor has the outstanding energy-saving characteristic, and more importantly, the motor has the control and dragging characteristics which cannot be achieved by the iron core motor. The novel rotor structure thoroughly eliminates the electrical energy loss caused by the eddy current formed by the iron core. The energy-saving characteristic energy conversion efficiency is very high, the maximum efficiency is generally above 70%, the control characteristic is quick to start and brake, the response is extremely quick, the mechanical time constant is less than 28 milliseconds (the iron core motor is generally above 100 milliseconds); in the high-speed running state in the recommended running region, the rotational speed can be conveniently and sensitively adjusted. Drag characteristics: the running stability is very reliable, the fluctuation of the rotating speed is very small, and the rotating speed fluctuation of the miniature motor can be easily controlled within 2 percent. In addition, the energy density of the hollow cup motor is greatly improved, and compared with an iron core motor with the same power, the weight and the volume of the hollow cup motor are reduced by 1/3-1/2. Because the hollow cup motor overcomes the insurmountable technical obstacle of the motor with the iron core, and the outstanding characteristics are concentrated on a follow-up system with main performances of the motor requiring quick response. For example, the flying direction of the missile is quickly adjusted, the follow-up control of a high-magnification CD-ROM drive, quick automatic focusing, high-sensitivity recording and detecting equipment, an industrial robot, a bionic artificial limb, a model airplane and the like, but the production automation degree is far lower than that of an iron core motor due to extremely complex coil production process of the hollow cup motor, so that the production cost is high, the labor cost is high, and the skill level requirement on an operator is high. The coil of the hollow cup motor can only be made thin, so the hollow cup motor can only be applied to the field of miniature motors, the torsion is low, the general power is only a few watts, the maximum power is hundreds of watts, and the new energy electric car motor is more than tens of kilowatts.

The new energy automobile three major core components, battery, motor and automatically controlled, wherein the motor generally adopts three-phase permanent magnet synchronous motor and three-phase alternating current induction motor, these are high-power alternating current motor, because the new energy automobile generally uses alternating current motor, and the output of group battery is direct current, just have to increase automatically controlled to rectify direct current into three-phase alternating current, this has increased the cost of ten percent more, still reduced the energy efficiency, the accident also takes place in faults such as electrical control system, the comprehensive energy efficiency is only about 85 percent, be equivalent to driving mileage and two hundred kilometers less, this is very important for new energy automobile now, the future standard requirement of china to new energy automobile motor is peak power ratio, 5 to 7 kilowatts per kilogram, duration 30 seconds.

In theory, a wireless transmitting end can be regarded as a point source from electromagnetics theory, but in reality, the wireless transmitting end is not a point source, or is a wireless transmitting square matrix formed by countless point sources, the space electromagnetic field outside the transmitting square matrix is divergent, but the electromagnetic field in the square matrix is closed, the electromagnetic field strength does not decrease with the square of the distance, the stronger magnetic flux density exists, if an open magnet with a self-contained magnetic field is adopted at the wireless receiving end, the receiving capability of wireless power is hundreds of times stronger than that of an induction coil, one or more magnets are put into a closed space electromagnetic field formed by an electric coil to serve as magnetic points, the mass and the volume of the magnet are not considered, and the magnet is assumed to be a magnetic point with certain magnetic field strength, so that no matter what electromagnetic wave forms, whether low-frequency or high-frequency, alternating current, long wave, short wave, microwave and the like exist, the magnetic points can resonate with electromagnetic waves of the transmitting end, the magnetic points can strengthen peripheral electromagnetic fields or can be regarded as part of the wireless transmitting end, so that the magnetic points in one wireless closed electromagnetic field can effectively and efficiently receive wireless electromagnetic energy, the application of household wireless power can be realized by adopting the magnetic point resonance in the wireless closed electromagnetic field, the real wireless charging of a mobile phone and an electric automobile and even a wireless power source of the electric automobile can be realized, the magnetic point resonance firstly oscillates at the same frequency, secondly rotates at the same frequency, the actual magnetic points are magnets formed by a plurality of magnetic points, the magnets have mass and volume, under the action of a changing electromagnetic field, inertia is generated by movement, the mass and the volume are more difficult to resonate with the changing electromagnetic field, and the resonance is more difficult to generate when the frequency is larger, otherwise, the resonance is more easy to generate when the frequency is smaller, in the case of the existing magnetic materials, the electromagnetic field below ten thousand hertz can be applied to realize wireless power transmission, and the actual effect is far better than that of the existing wireless power transmission technology although the frequency is low.

The magnitude of the electromagnetic force of the closed electromagnetic field established by the wire coil is proportional to the total section current of the wire, is proportional to the length of the wire coil, is inversely proportional to the square of the distance, is proportional to the magnetic quantity of the magnetic point, and is also related to the vector direction of the magnetic field. According to the theory of magnetic points, the magnetic points can not only receive wireless power with high efficiency, but also be used as motors and generators with synchronous rotation of circumference, the energy efficiency is more than ninety-nine percent, and the power quality ratio is the largest at present. According to the theory of magnetic points, radio waves, alternating current and a changing magnetic field are not essentially different, the magnets are the same in alternating current coils and in radio waves, and the magnetic point motor is a wireless power receiving end.
