MOTOR AND BLOWER

摘要

A motor includes a stator and a rotor. The stator includes an inner circumference stator section and an outer circumference stator section. The inner circumference stator section and the outer circumference stator section each include two stator cores and a coil. The two stator cores each include claw poles and are coupled to each other. The coil is arranged between the two stator cores. The rotor includes an inner circumference magnet and an outer circumference magnet. The inner circumference magnet, which is arranged at an inner circumferential side of the inner circumference stator section, opposes the claw poles in the radial direction. The outer circumference magnet, which is arranged at an outer circumferential side of the outer circumference stator section, opposes the claw poles in the radial direction. The inner circumference stator section and the inner circumference magnet form an inner circumference motor unit. The outer circumference stator section and the outer circumference magnet form an outer circumference motor unit.

1. A motor comprising:
a stator including an inner circumference stator section and an outer circumference stator section, which is located at an outer circumferential side of the inner circumference stator section, wherein the inner circumference stator section and the outer circumference stator section each include
two stator cores each including a plurality of claw poles in a circumferential direction, wherein the stator cores are coupled to each other so that the claw poles of one of the stator cores and the claw poles of the other one of the stator cores are alternately arranged in the circumferential direction, anda coil located between the two stator cores in an axial direction to cause the claw poles to function as magnetic poles; and a rotor rotated by a rotating magnetic field generated at the stator, wherein the rotor includes
an inner circumference magnet located at an inner circumferential side of the inner circumference stator section and opposed to the claw poles in a radial direction, andan outer circumference magnet located at an outer circumferential side of the outer circumference stator section and opposed to the claw poles in the radial direction, wherein the inner circumference stator section and the inner circumference magnet configure an inner circumference motor unit, and the outer circumference stator section and the outer circumference magnet configure an outer circumference motor unit.
