Problems solved by technology

[0004] The disadvantage of AC three-phase asynchronous motor and AC three-phase variable frequency asynchronous motor is asynchronous (the speed of the rotating magnetic field of the stator is not synchronous with the speed of the rotor) motor, so the rotor must have an induced excitation current to rotate, and there is a slip. In this way, the efficiency of this type of motor will not be high, and the power saving rate will be extremely poor.
[0005] 2. The structure of the current DC motor is complex, which limits the reduction of volume and weight, especially the sliding contact between the brush and the commutator causes mechanical friction and sparks, resulting in high failure rates, low reliability and long life of the DC motor. Short, maintenance workload is heavy, and DC power supply is used, the commutation spark not only causes the electric corrosion of the commutator, but also is a source of radio interference, which will bring harmful interference effects to the surrounding electrical equipment
Therefore, the brushes and commutators of DC motors limit the development of DC motors to high speed and large capacity, and the efficiency of DC motors is very low, and the power saving rate is extremely poor.
[0006] 3. Permanent magnet synchronous motors and servo motors are better than AC asynchronous motors, AC variable frequency asynchronous motors, and DC synchronous motors in terms of performance and operating efficiency. The disadvantage is that the temperature of permanent magnets in the rotors of permanent magnet synchronous motors and servo motors rises once the motor is running. High, mechanical vibration and the impact of power supply surge current are prone to irreversible demagnetization, that is, the motor will be scrapped immediately, and the magnetic field strength of the rotor permanent magnet of the permanent magnet motor will decay with the passage of time, that is, The actual output power of this motor will become smaller, and these two motors cannot be made large, and this type of motor is particularly delicate, and the rotor permanent magnet of this type of motor uses rare earth (rare earth has become a national strategic resource), which limits this type of motor. The development and large-area application of similar motors, and their operating efficiency is not ideal

The niobium-titanium alloy material includes the following components: metal niobium (Nb) accounts for 50%-55%, and metal titanium (Ti) accounts for 50%-55%. Specifically, in this embodiment, metal niobium (Nb) accounts for 53%, and metal titanium (Ti) accounts for 47%. Of course, metal niobi...

Embodiment 2

[0031] This embodiment is optimized on the basis of the above-mentioned Embodiment 1.

[0032] The rotor main body 2 is uniformly provided with permanent magnets 4 with high temperature resistance and high magnetic flux in the circumferential direction.

[0033] The rotor is equipped with high temperature and high magnetic flux permanent magnets 4 that are not afraid of vibration and can withstand instantaneous high temperatures of 2000°C, so that the output power of the motor will not decrease due to the decay of the magnetic field strength of the rotor with the passage of time. The rotor provides induced excitation current, which can generate strong torque, so the motor is more energy-efficient.

[0034] The rotor adopts permanent magnet 4 with high temperature resistance and high magnetic flux, which is resistant to high temperature, vibration and current impact, and does not require excitation power to provide excitation current to the rotor, so the rotor of this motor has...

Embodiment 3

[0038] This embodiment is optimized on the basis of the above-mentioned Embodiment 2.

[0039] The stator body 6 is made of nanocrystalline alloy material.

[0040] The stator body 6 is a nanocrystalline alloy, which is similar to an oxide with infinite internal resistance, so there is no eddy current loss, iron loss and hysteresis loss which can be ignored, and the motor is more energy efficient.

[0041] The iron core is made of nanocrystalline alloy material. The production process of this material is to spray high-temperature molten iron through a narrow slit to the surface of a high-speed rotating cooling copper roll, and obtain an amorphous alloy material by an extremely cold method. After further appropriate heat treatment process, A nanocrystalline alloy strip with soft magnetic properties is obtained. The initial magnetic permeability of the strip is 110,000-130,000, and the magnetic saturation density is 1.3T, which is many times that of the best quality silicon stee...

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a semi-superconducting ultra-high-efficiency energy-saving motor. Background technique [0002] The motors commonly used by enterprises today are divided into: AC three-phase asynchronous motors, AC three-phase variable frequency asynchronous motors, DC synchronous motors, permanent magnet synchronous motors and servo motors. [0003] 1. The current AC three-phase asynchronous motor is an induction motor and an AC three-phase variable frequency asynchronous motor. Its operation principle: When the three-phase stator windings of the motor (each with a difference of 120 degrees in electrical angle) are connected to the three-phase symmetrical alternating current, it will generate A rotating magnetic field, which cuts the rotor winding, thereby generating an induced current in the rotor winding (the rotor winding is a closed path), and the current-carrying rotor conductor will genera...
