Kind Code:
A1
Abstract:
[Problem] To improve controllability in a motor having a stator having a two-split structure. [Solution] A motor 400 comprises a stator 460 disposed on the outer periphery of a rotor 440 rotating integrally with a drive shaft 420. The stator 460 includes: an inner core 462 having a plurality of projection parts 462B extending radially outward from the outer peripheral surface of a cylindrical part 462A; and a cylindrical outer core 464 in which the tip of the projection part 462B is attached to an inner peripheral surface side. A connection part (first connection part 462F) between an outer peripheral surface of the cylindrical part 462A and an upstream side surface (first side surface 462D) of the rotor 440 in a rotation direction in the projection part 462B has an R shape. A connection part (second connection part 462G) between the outer peripheral surface of the cylindrical part 462A and a downstream side surface (second side surface 462E) of the rotor 440 in the rotation direction in the projection part 462B has an R shape. The radius r1 of the R shape of the first connection part 462F is larger than the radius r2 of the R shape of the second connection part 462G.
