DRIVE MOTOR OF TURBOCOMPRESSOR

摘要

PURPOSE: A turbo compressor driving motor is provided to compact an impeller combined with the ends of a driving shaft and a compressor, and to maintain a regular compression ratio by reducing windage loss and by rotating at high speed. CONSTITUTION: Flux is formed according to current of a winding coil(260) when applying current to the plural winding coils alternately. The interaction between the flux formed by the winding coils and the magnetic force of a magnet turns a rotor(270) by rotational force. A driving shaft(300) rotates by turning the rotor, and first and second impellers combined with both ends of the driving shaft suck and compress coolant gas with rotating in first and second compression chambers. The rotor has the magnet, and the same diameter as a diameter of the driving shaft. The windage loss is reduced by coolant gas between the rotor and a stator(s) at high-speed rotation, and the efficiency of the motor is improved.
