Permanent magnet rotor

摘要: PURPOSE: To enable correspondence to revolution at high speed by forming a plurality of protruding sections, width which is broadened outward in the radial direction, outer circumferential surface yoke and shaping longitudinal grooves corresponding sections inner segment magnet. CONSTITUTION: A 3e 3h, toward outside direction have height lower than thickness magnets 4a 4d, are formed 3. The axial length segments 4d shaped manufactured approximately same as 3, 4e 4h 3h 3 surfaces 4d. permanent magnet rotor assembled such manner that press-fitted shaft 2 engaged fixed yoke. Accordingly, work wedge support magnets, thus allowing speed. COPYRIGHT: (C)1990,JPO&Japio
