摘要： In an electric motor, each tooth of the stator has a radially extending pillar portion and the number of teeth per magnetic pole is k. When the number k is odd and a center line passing each pole agrees with a center of a circumferential width of one tooth, the pole has first and second corners which are the closest to the stator and positioned before and after the center line in a rotational direction, respectively, and the teeth includes teeth which are the closest to the first and second corners and defined as first and second teeth, respectively. The first and second corners are located according to positional relationships of the first and second teeth and edges of the pillar portions of the first and second teeth in the rotation direction.

摘要： A rotor includes a hollow cylindrical rotor core that has a center hole, in which a rotating shaft is to be press-fitted, and a plurality of magnet-receiving holes in which a plurality of permanent magnets are respectively received. In a radially inner surface of the rotor core defining the center hole, there are formed a plurality of non-contacting recesses and a plurality of contacting protrusions alternately in the circumferential direction of the rotor core. Each of the non-contacting recesses is recessed radially outward so as not to be in contact with the rotating shaft. Each of the contacting protrusions protrudes radially inward so as to be in pressed contact with the rotating shaft. The rotor core further has a plurality of through-holes each of which penetrates the rotor core in the axial direction of the rotor core and is located radially outside a corresponding one of the contacting protrusions.

摘要： A multilayer laminated rotor is mountable on a shaft for rotation relative to a stator of a rotary electric machine arrangement. The rotor has a plurality of laminas, joined together, and voids for receiving magnets. An annular rotor section, which surrounds a shaft opening within which the shaft is receivable, extends between the shaft opening and a radially outer circumferential rotor surface. The annular section mentioned includes an undulating series of the voids in void groups extending from the radially outer circumferential rotor surface inwardly toward the shaft opening and then back toward the radially outer circumferential rotor surface, as well as a solid radially interior portion without any of the voids. Distal voids in the void groups include curved, arcuate, or recurved stress relieving features extending inwardly from radially innermost corner locations of the distal voids.

Thus, the ratio of the torque constant to the moment of inertia can be improved so that the current required for driving can be reduced and reduction of power consumption at driving time can be attained.
