Abstract: A direct current motor having pole pieces in the shape of partial cylinders each having an inner surface terminating in a leading and trailing edge. A series of notches are formed along the edges of the pole pieces so that each of the edges alternately slopes toward and away from the center of the inner arc surface of the pole piece.

Abstract: An electric rotating machine includes a field permanent magnet which is permanently magnetized to N and S poles alternatively and an armature core which is arranged coaxially with the magnet and has a plurality of salient poles facing to the magnet. Poly-phase coils are wound on the root of the salient poles. By providing an indented portion at the major face of the salient pole facing the magnet, the cogging torque can be remarkably reduced, and further by providing auxiliary salient poles ripple torque can be also reduced.

Abstract: The present disclosure provides a rotor unit, a rotor, and a motor structure. The rotor unit includes: a rotor punching sheet; a plurality of magnet units comprising a magnet and arranged on the rotor punching sheet; and a hole structure arranged in the magnet. The rotor includes a plurality of rotor units. The motor structure includes: the rotor, a first flow guide plate having a central hole and arranged between two adjacent rotor units, and a central shaft passing through a center of the rotor and the central hole. The present disclosure can effectively reduce the cost of the magnets, and can achieve a direct cooling of the magnets, the rotor and the stator, reduce the eddy current effect, reduce costs, and greatly expand an optimization and use range of the motors when applied in the motors.

Abstract: A rotor includes a shaft, a rotor core with core pieces arranged axially, and a plate between adjacent core pieces and surrounding the shaft. The shaft includes an axial first hole, and a second hole opened to outside of the shaft and connected to the first hole. One side of the plate in the axial direction has a first surface at an inner edge of the plate, and a second surface radially outward from the first surface. The first and second surfaces are away from the core piece, which is on the one side of the plate in the axial direction, toward the other side. The plate includes through-holes on the second surface and arranged circumferentially at intervals, and a plate wall protruding to one side in the axial direction from a portion of the first surface positioned radially outward from an inner edge.
