    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 is to enable simple manufacture of a motor, especially, a stator core or a field without impairment of motor characteristics. The motor includes a shaft (20), a rotor (31) fixed to the shaft (20), and a stator (21) including a stator core (24) that faces the rotor (31) with a certain space therebetween and coils (23) that are attached to the stator core (24). The stator (21) includes a back yoke (24a), and the stator core (24) having a plurality of teeth (24b) that are circumferentially placed in an axial end face of the back yoke (24a) so as to stand upright axially of the back yoke (24a), and that are formed of a dust core made of pressed magnetic powder. The above-mentioned teeth (24b) are buried axially to a certain depth in the back yoke (24a).

    摘要: The present invention relates to a core, a rotor, a motor and a compressor. It is an object of the present invention to prevent a short circuit of magnetic flux especially in a rotor. In order to attain this object, a rotor (1a) comprises a core (11) extending in a predetermined direction (91), and a plurality of magnets (21). The core (11) has parts (111, 112) formed by magnetic materials and extending in the predetermined direction (91). The parts (112) are arranged in a loop around the part (111), and face the part (111) through gaps (41). The magnets (21) are buried in the gaps (41) in the form of a loop in the core (11). The magnets (21) have pole faces (211, 212) extending in the predetermined direction (91). In each of the magnets (21), at least one of ends (21a, 21b) of the magnet (21) protrudes forward in the predetermined direction (91) with respect to an end (111a, 111b) of the part (111) that is on the same side with the at least one of the ends of the magnet.

    摘要: A radial gap type rotating electrical machine which inexpensively enhances a demagnetization resistance of a permanent magnet without deteriorating torque characteristics and efficiency characteristics is provided. An outer rotor type radial gap type rotating electrical machine (9) includes a field (1) and an armature (2). The field (1) includes a permanent magnet (11) and a magnetic ring (12) which serves as a back yoke of the permanent magnet (11). The magnetic ring (12) is provided at a position farther from the armature (2) than the permanent magnet (11), and includes a recess (121) at a magnetic pole center (110). The magnetic pole center (110) is a center of a magnetic pole concerning a circumferential direction with respect to a rotation axis (3). A thickness of the recess (121) in the radial direction around the rotation axis (3) as a center comes to locally thin.
