Cooling structure for rotor core in electric rotating machine |
摘要 |
A rotor for an electric rotating machine includes d-axis through holes located on respective d-axes, hollow shafts formed in both axial sides of a rotating shaft not inserted into a rotor core, presser plates mounted on both axial ends of the rotor core, cooling grooves formed in faces of the presser plates in contact with the rotor core, a plurality of presser plate refrigerant outlet holes in the presser plates, the presser plate refrigerant outlet holes of one of the presser plates having diameters different from diameters of the presser plate refrigerant outlet holes of one of the other presser plates, and a refrigerant channel formed so that a refrigerant supplied into one of the hollow shafts of the rotating shaft flows through the refrigerant channel and further through the hollow shaft wall hole of said one hollow shaft and the radial grooves of the respective presser plates. |
