Abstract: A synchronous motor is driven by three phase alternate current. The rotor core includes a laminated body configured by laminating plate members made of electrical steel sheet. Each plate member is formed in a substantially circular shape in a plan view and formed with projections along an outer circumference thereof.The number of slots of the stator is 3xy when variable x is a natural number and variable y is a positive odd number. The number of poles of the rotor is (3y+1)x or (3y−1)x. The number of projections of each plate member is a common measure of (3y+1)x and (3y−1)x. The laminated body has a structure in which the plate members are laminated so that the projections are shifted relative to one another.

Abstract: Provided is a stator that can easily attach a coil to a tooth and that can reduce concentration of stress generated in the core during the operation. The stator includes a core with an annular back yoke, and a plurality of teeth aligned in a circumferential direction, each tooth extending toward a radially inside from the back yoke; and a coil wound around each of the plurality of teeth. The core includes a plurality of divided cores aligned in the circumferential direction. Each divided core includes the tooth, and a divided back yoke extending from an end on a radially outside of the tooth to a first circumferential side. A radial width of the divided back yoke is smaller than or equal to a circumferential width of the tooth. A connecting surface is arranged at an end on a second circumferential side of the divided yoke, the connecting surface being a plane or a convex surface extending from a side surface on the second circumferential side of the tooth to an outer circumferential surface of the divided back yoke.
