MAGNETIC CORE, ARMATURE, ELECTRIC ROTARY MACHINE AND COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To reduce an eddy current generated in teeth and a yoke. SOLUTION: An armature 100 is provided with a magnetic core 1 and a winding 13. The magnetic core 1 is provided with the yoke 11 and the teeth 12. The yoke 11 has a magnetic body plate 111 wound around a center shaft 92 along a predetermined direction 91. The teeth 12 are disposed on a surface 11a circularly along a circumferential direction 93 around the center shaft 92. The teeth 12 each have a magnetic body plate 121 wound around a shaft 94 determined for a position of each of them. The shaft 94 is substantially parallel to the predetermined direction 91. The winding wire 13 is disposed on the teeth 12. COPYRIGHT: (C)2008,JPO&INPIT
