摘要：A rotor includes a hollow cylindrical rotor core that has a center hole, in which arotating shaft is to be press-fitted, and a plurality of magnet-receiving holes in which aplurality 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-contactingrecesses and a plurality of contacting protrusions alternately in the circumferentialdirection of the rotor core. Each of the non-contacting recesses is recessed radiallyoutward so as not to be in contact with the rotating shaft. Each of the contactingprotrusions protrudes radially inward so as to be in pressed contact with the rotatingshaft. The rotor core further has a plurality of through-holes each of which penetratesthe rotor core in the axial direction of the rotor core and is located radially outside acorresponding one of the contacting protrusions.
