High-frequency motor with superconducting liquid heat dissipation and composite powder conductive wire winding stator rotor

Abstract

A high-frequency motor composed of a superconductive liquid heat-dissipation stator and a rotor wound with composite powder electric leads consists of the stator and the rotor, wherein the stator comprises a housing, a stator iron core and a stator winding, and the rotor comprises a rotary shaft, a rotor iron core and a rotor winding. The high-frequency motor is characterized in that a centrifugal fan blade is respectively installed on the rotary shaft outside two ends of the rotor iron core, the outer side faces of the centrifugal fan blades are provided with air inlet holes, and the circumferential faces of the centrifugal fan blades are provided with air outlet holes. The lead wire of the rotor winding is embedded into a through hole of the rotor iron core, extends out of two sides of the rotor iron core to be bent so as to extend out of the tail end and face the air outlet holes of the centrifugal fan blades. The cross section of each of the lead wires of the stator winding and the rotor winding is of a four-layer structure including insulating resin, an outer heat-conducting pipe, composite conductive powder and an inner heat-conducting pipe from outside to inside, and 2 / 3 volume of superconductive liquid is added into the inner heat-conducting pipes for heat dissipation. The problem that an existing electric motor is poor in heat dissipation and skin effect is solved, and the high-frequency motor composed of the superconductive liquid heat-dissipation stator and the rotor wound with the composite powder electric leads has the advantages of being good in heat-dissipation effect, high in electric conductivity, long in service life, reliable in use and the like.

Description

1. Technical field [0001] The invention relates to a motor, in particular to a high-frequency motor in which superconducting liquid dissipates heat and composite powder conductive wire winds a stator rotor. 2. Background technology [0002] Under normal working conditions of various household single-phase motors, the surface temperature of the motor shell is generally about 20°C higher than the ambient temperature, and the maximum temperature rise should not be higher than 70°C. If the surface temperature of the motor rises sharply after the motor has been working for a few minutes, and the inside of the motor emits a tar smell or even smoke, it means that the motor is overheating. The reasons for the overheating and temperature rise of the motor mainly include the quality of the motor itself; the motor is in an overloaded state for a long time (the fault of the transmission mechanism causes the motor load to be large); the cooling condition of the motor is poor; the motor w...

Thus, the skin effect makes a wire-type transmission line inefficient at high frequencies because the signal is attenuated significantly as it travels along it
