Title:
FLUID MACHINE AND TRANSMISSION
Document Type and Number:
Japanese Patent JP2017166467
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a temperature rise of a magnetic body included in a transmission using magnetic force.SOLUTION: A fluid machine is equipped with an electric motor 11; an impeller 12; and a transmission 13 provided between the electric motor and the impeller. The transmission has a first rotor 14 which is coupled to the electric motor and has a magnet on which magnetic poles are alternately disposed in a circumferential direction so as to generate magnetic force on an outer periphery; a second rotor 15 which is coupled to the impeller and has a magnet on which magnetic poles are alternately disposed so as to generate magnetic force on an inner periphery; a housing 16 surrounding a second rotor in the circumferential direction; and a plurality of magnetic bodies 17-1, 17-6 which are disposed between the first rotor and the second rotor at an interval in a diametrical direction, spaced from each other in the circumferential direction, and coupled to the housing.SELECTED DRAWING: Figure 1
