Abstract

PURPOSE:To prevent deformation due to centrifugal force at the time of revolution at high speed by incorporating a light-weight high-strength nonmagnetic material into a groove formed onto the outer circumferential surface of an outer circumferential section and mounting a retaining ring composed of a circumferential magnetic material section and a nonmagnetic material section on the outer circumferential surface side of the outer circumferential section. CONSTITUTION:A rotor 10 is composed of a core section 11 consisting of a magnetic material and an outer circumferential section 20 made up of a permanent magnet 13 incorporated into the core section 11. The outer circumferential section 20 consists of the permanent magnet 13 and a retaining ring 14 arranged on the outer circumferential surface side of the permanent magnet 13 and supported by sidewall sections 12. The retaining ring 14 is divided into four in the circumferential direction, and magnetic material sections and nonmagnetic material sections are disposed alternately.
