Ultra-high-speed integrated motor with internal inductance capable of being steplessly adjusted

Abstract

The invention relates to an ultra-high-speed integrated motor with internal inductance capable of being steplessly adjusted, and belongs to the technical field of motors. According to the invention, astator and a rotor of a set of electric reactor are additionally arranged outside normal stator teeth, coils are wound on the stator teeth of the electric reactors and fixed on the motor stator, andthe rotor is fixed on a shell and can slide back and forth through a push button outside the shell, so that the coupling area between the stator teeth and the rotor teeth of the electric reactor is adjusted so as to further change the magnetic conductivity of a magnetic circuit, and stepless adjustment of the internal inductance is realized so as to adapt different working conditions by adjustingthe inductance value, simplify the working system of the motor and improve the working efficiency of the motor; compared with the traditional mode of limiting the motor stator winding current by an external series reactor, the series inductor provided by the invention has the advantages that the inductance value can be randomly adjusted, and the adjustment range is wide enough; and on the basis ofensuring the working safety of the motor, the ultra-high-speed integrated motor has the advantages of being more flexible and more suitable for complex and changeable working conditions of the motor.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to an ultra-high-speed integrated motor whose internal inductance can be adjusted steplessly. Background technique [0002] With the development of the power industry, more and more key projects require the technical support of ultra-high-speed motors, so ultra-high-speed motors have become an important research content in the field of electrical engineering in my country. Compared with traditional motors, ultra-high-speed motors are small in size, directly connected to the prime mover without a deceleration structure, and have a small moment of inertia. Therefore, they have the advantages of saving materials, high speed, high power, fast response, and high transmission efficiency. RPM requirements. However, the rotor speed of the ultra-high-speed motor is high, and the impedance of the stator winding is small, so it is easy to generate excessive stator winding current, ...

Problems solved by technology

However, when the working conditions change, different reactors need to be replaced, which makes the working system of the motor more complicated and limits the working efficiency of the motor

[0009] However, the technical scheme of filtering the stator winding current harmonics through LC filtering only plays a role in suppressing the current harmonics, and cannot fundamentally solve the problem of excessive stator winding current caused by the small stator winding impedance value, and this scheme It makes the motor working system more complex and has many limitations
