This utility model discloses a quick clamping device for sensor patches, including a quick clamping mechanism, a pressure head, a clamping body, and screws. The quick clamping mechanism is adjustablely installed at one end of the clamping body, and the pressure head is located at the other end of the clamping body. It is used to press the sensor placed in the clamping body against the end of the quick clamping mechanism. The screw is threaded onto the clamping body to lock the quick clamping mechanism. By setting a push-pull quick clamp, the sensor patch can be quickly clamped. Compared with the traditional clamping method, the work efficiency is greatly improved, meeting the needs of quick positioning and fixing of sensor patches in the production process. By setting a spring and a pressure plunger, when the quick clamping mechanism is pushed, the sleeve position is fixed and the stroke of the quick clamp is fixed. Therefore, after the quick clamp is pulled down, the compression distance of the spring is fixed, so the clamping force provided is constant, thereby providing a stable force in the pressure curing process.

The application provides a magnetic phase-shifting transformer based on vector magnetic circuit theory and an application method thereof. The magnetic phase-shifting transformer is composed of a target transformer magnetic circuit and a magnetic induction element matrix. The equivalent magnetic resistance of the magnetic phase-shifting transformer magnetic circuit and the equivalent magnetic reactance of the magnetic phase-shifting transformer magnetic circuit are adjusted, so that the magnetic flux phase angle of the magnetic phase-shifting transformer is continuously controlled. Meanwhile, by adjusting the equivalent magnetic resistance of the magnetic phase-shifting transformer magnetic circuit and the equivalent magnetic reactance of the magnetic phase-shifting transformer magnetic circuit, the magnetic circuit cutoff frequency is adjusted, so that the harmonics in the magnetic circuit are filtered, and the active power and the reactive power of the magnetic circuit are controllably distributed. By dynamically controlling the parameter configuration, combination mode and switching state of the magnetic induction element, the magnetic flux phase in the core is directly adjusted in a wide range, so that the phase-shifting of the voltage of the secondary winding of the transformer relative to the voltage of the original winding is realized, and the harmonic filtering and the reactive power compensation of the magnetic circuit are realized.

The application discloses a multi-excitation-source partition-level variable-pole type axial magnetic field permanent magnet motor and a variable working condition driving control system, mainly comprising two parts of a main magnetic pole and an auxiliary magnetic pole, wherein the main magnetic pole is responsible for providing a main magnetic flux of an air gap and is connected in series with a double-stator magnetic circuit; the auxiliary magnetic pole is responsible for adjusting an air gap magnetic field and is connected in parallel with the double-stator magnetic circuit; the main magnetic pole and the auxiliary magnetic pole magnetic flux jointly constitute the air gap magnetic field, and the magnetic flux path of the auxiliary magnetic pole can be controlled by controlling the current size added to the excitation winding, thereby adjusting the air gap magnetic flux, widening the motor speed regulation range, realizing the multi-variable working condition operation of the motor, and further reducing the torque ripple, improving the power density, realizing the high-efficiency and high-reliability operation of the motor, and improving the dynamic working performance of the motor.
