High-efficiency heat-dissipation variable-frequency speed-regulation three-phase asynchronous motor

Abstract

The invention discloses an efficient heat dissipation variable frequency speed regulation three-phase asynchronous motor, and belongs to the field of three-phase asynchronous motors. After relatively cold cooling oil in an inner cavity of a cold circulation pipe enters a hollow cold arc following block, the temperature of a carbon dioxide air bag ball is reduced, so that the carbon dioxide air bag ball is shrunk; the cooling oil entering the hollow refrigeration arc block enters an inner cavity of the cold circulation pipe to wait for the next round of extrusion and pushing of the carbon dioxide air bag ball by heating and indirect circulation of the cooling oil, so that the heat dissipation efficiency is improved, the cooling oil entering the hollow refrigeration arc block is rapidly cooled through saltpeter particles, and the cooling effect is improved. The cooled cooling oil flows to the inner cavity of the cold circulation pipe through the cambered surface of the inner bottom end of the hollow refrigeration arc block, and is extruded to the hollow cold circulation arc block in cooperation with expansion of the carbon dioxide airbag ball, indirect circulation heat conduction is conducted on the inner cavity of the motor shell body, and the heat conduction effect of the inner cavity of the motor shell body is further improved in cooperation with saltpeter particles.

Description

technical field [0001] The invention relates to the field of three-phase asynchronous motors, and more specifically relates to a three-phase asynchronous motor with high-efficiency heat dissipation and frequency conversion speed regulation. Background technique [0002] The single-layer winding is a winding in which only one effective side of the coil is embedded in each stator slot, so the total number of coils is only half of the total number of slots of the motor. The advantage of the single-layer winding is that the number of winding coils is small and the process is relatively simple. The utilization rate of the insulation slot is improved, and the phase-to-phase breakdown fault will not occur in the single-layer structure. The disadvantage is that the electromagnetic waveform generated by the winding is not ideal, the iron loss and noise of the motor are large, and the starting performance is also slightly poor. Windings are generally only used in small-capacity asynch...

[0003] A high-efficiency heat dissipation variable frequency speed regulation three-phase asynchronous motor heats up quickly during operation. The shell of a traditional high-efficiency heat dissipation variable frequency speed regulation three-phase asynchronous motor is not convenient for rapid heat conduction of the internal heat, and its heat conduction cooling effect is relatively low.
