    摘要： A motor having a rotor and a stator is disclosed. The rotor is a consequent-pole rotor having a rotor core, a plurality of magnets, and a plurality of salient poles. The stator includes a plurality of teeth. A first auxiliary groove is formed in a surface of each salient pole that is opposed to the teeth. Each first auxiliary groove has first and second side surfaces facing each other in the circumferential direction. The first side surface is closer to a circumferential center of the salient pole than the second side surface. When the angle from the circumferential center line to the first side surface of each salient pole about the axis of the rotor is represented by KC1, the opening angle between the circumferential ends of the distal end of each tooth about the axis is represented by KA, and the opening angle between the circumferential ends of each salient pole about the axis is represented by KB, the following expression is satisfied: KC1=KA−KB/2.

    摘要： A pneumatic tire with a tread has crown main grooves, shoulder main grooves, a pair of middle ribs between the crown main grooves and the shoulder main grooves, and a pair of shoulder ribs between the shoulder main groove and tread edge. The shoulder rib has shoulder lateral grooves spaced at a pitch Ps. The middle rib has middle inclined grooves spaced at a pitch Pm. The crown rib has a plurality of crown lateral grooves which cross over the crown rib and are spaced at a pitch Pc. The pitch Pc is larger than the pitch Ps and smaller than the pitch Pm.
