Abstract
A compressor includes: a compressor; and a motor that is disposed in the compressor housing. The motor has a rotor provided coaxially with respect to a rotary shaft of the compression part, and a stator disposed on an outer peripheral side of the rotor. In the stator, a plurality of large-diameter parts in contact with an inner peripheral surface of the compressor housing and a plurality of small-diameter parts, each of the small-diameter parts having a distance from a rotation center of the motor to an outer peripheral surface, the distance being smaller than the distance of the large-diameter part, are formed in a circumferential direction of the stator. The stator is provided with a plurality of welded parts joining the inner peripheral surface of the compressor housing with the outer peripheral surface of the stator, and the welded parts are provided in the small-diameter part of the stator.
