摘要： A stator (5) includes a stator core (510) in which an annular back yoke (511) is integrated with a plurality of teeth (512) circumferentially arranged on the back yoke (511) at intervals, and an insulator (530, 1530) that sandwiches the stator core (510) from both axial sides of the stator core (510). The insulator (530, 1530) is molded integrally with the stator core (510) through resin molding in such a way that the insulator (530) covers an inner surface of a slot portion (514) of the stator core (510). Thereby a stator that can be assembled by a simpler process is provided.

摘要： There is provided a stator capable of securely preventing radial coming-out of an inter-coil insulator. A stator (5) includes: a stator core (510) having a plurality of tooth portions (512) arrayed with circumferential intervals therebetween; an insulator (530) attached to axial both end faces of the stator core (510); a coil (520) which is wound around the tooth portions (512) of the stator core (510), with the insulator (530) interposed therebetween; and an inter-coil insulator (100) placed between circumferentially mutually neighboring ones of the coil windings (520). The inter-coil insulator (100) is folded at a folding-bottom portion (102) provided so as to extend in an axial direction. The folding-bottom portion (102) is positioned on a distal end side of the tooth portions (512), and a circumferential width of the folding-bottom portion (102) is larger than a circumferential width of a slot opening (95).

摘要： A rotor 6 includes a rotor core 610, and a plurality of magnets 620 arrayed on the rotor core 610 in its circumferential direction at center angles of equal intervals. Given an axial length L of the rotor core 610, a radial length D of the rotor core 610, and a thickness t of the magnets 620, the following relationships are satisfied: L/D (1×K×)/(L 1.5 ×D×P) (wherein P is the number of poles, K is 100000, and N is a factor that depends on the output of the compressor). Thus, while torque decreases due to large reduction in rotor layering thickness is suppressed, a small-size, lightweight and low-priced compressor motor is provided.

摘要： An object of the present invention is to improve the magnetic flux density on a rotor surface. A first non-magnetic portion (13), a second non-magnetic portion (14), and a third non-magnetic portion (16) are arranged around an axis (Q), from an end toward the center of a permanent magnet burying hole (12). A fourth non-magnetic portion (15) is further provided between the second non-magnetic portion (14) and the third non-magnetic portion (16). Angles around the axis are determined as follows with reference to a position between permanent magnet burying holes. The position between the first non-magnetic portion and the second non-magnetic portion is expressed by a first angle (θ7). The position between the third non-magnetic portion and the fourth non-magnetic portion is expressed by a second angle (2-θ7), and the second angle is twice the first angle. The end of the third non-magnetic portion located closer to the pole center is expressed by a third angle (θ3). The first angle and the third angle are values obtained by dividing 360 degrees respectively by a value that is seven times, and a value that is three times, the number of the permanent magnet burying holes.

摘要： High efficiency of a compressor that compresses a mixed refrigerant containing at least 1,2-difluoroethylene is achieved. A compressor (100) includes a motor (70) that has a rotor (71) including permanent magnets (712) and thus is suitable for a variable capacity compressor in which the number of rotations of the motor can be changed. In this case, it is possible to change the number of rotations of the motor in accordance with an air conditioning load in an air conditioner (1) that uses a mixed refrigerant containing at least 1,2-difluoroechylene. It is thus possible to enable high efficiency of the compressor (100).

摘要： It is aimed to provide a field element capable of easily measuring an air gap between magnetic poles while making a waveform of a magnetic flux density close to a sinusoidal wave. A field element core (1) has a perimeter (10) exposed around a rotation axis (P) and a plurality of field magnet insertion holes (30) circularly disposed around the rotation axis P. A radius (R) between the perimeter (10) and the rotation axis P decreases in a monotonically non-increasing manner from a pole center (101) toward an interpole (102) and then increases in a monotonically non-decreasing manner in a region between the pole center (101) and the interpole (102) in a circumferential direction (D).
