Abstract
A scroll compressor includes a scroll compression mechanism, a motor, and a casing. The motor includes a stator having a stator core and an insulator, a rotor disposed inside the stator, a coil wound around a plurality of teeth of the stator core via the insulator, and an outgoing line at an end of the coil. When the motor is viewed along a rotation axis of the rotor, at least one of the outgoing line and a film wound around the outgoing line satisfies 0.65<(D1−da)/(D1−D2)<0.95. An outer radius of the teeth centered on a position of the rotation axis of the rotor is D1. An inner radius of the teeth is D2. An average distance from the position of the rotation axis of the rotor to the at least one of the outgoing line and the film wound around the outgoing line is da.
