回転子、電動機、圧縮機、冷凍サイクル装置、及び空気調和装置
Document Type and Number:
Japanese Patent JP7389146
Kind Code:
B2
Abstract:
A rotor (4) is a rotor in a motor (6) for driving a compression mechanism part (21) that compresses a refrigerant (20). The rotor (4) has a permanent magnet (45) including a plurality of crystal grains (45a), and an average crystal grain diameter of the plurality of crystal grains (45a) is 1.6 µm to 12 µm. The motor (6) includes the rotor (4) and a stator (5). A compressor (10) includes the motor (6), the compression mechanism part (21), and a container (30) that accommodates the motor (6) and the compression mechanism part (21). A refrigeration cycle apparatus (100) includes the compressor (10), a condenser (101) that condenses the refrigerant (20) sent out from the compressor (10), an expansion device (102) that expands the refrigerant condensed by the condenser (101), and an evaporator (103) that evaporates the refrigerant (20) flowing out of the expansion device (102).
