Abstract

See full text

A rotary compressor includes a compression mechanism, a casing, a motor stator and a motor rotor. The motor stator includes stacked steel plates, teeth, and slots. The stacked steel plates are fixed to an inner surface of the casing. A number of the teeth and slots is nine. The motor rotor rotates a crankshaft to drive the compression mechanism. The stacked steel plates have first to ninth areas radially outside the nine teeth, first concave portions provided in five of the areas, and a second concave portion provided in at least one of four areas other than the five areas. The five first concave portions and an inner circumferential surface of a cylindrical portion form five first passages. The second concave portion and the inner circumferential surface of the cylindrical portion form at least one second passage.
