ROTOR FOR ELECTRIC ROTATING MACHINE |
摘要 |
An iron rotor core includes a first permanent magnet in an outer peripheral portion of the iron rotor core, second permanent magnets on both circumferential sides of the first permanent magnet and arranged in a generally V-shaped configuration opening radially outward, and a first region provided opposite to the first permanent magnet radially inside the region between the second permanent magnets and having a low magnetic permeability. A q-axis magnetic flux path is formed in an iron core region among the first permanent magnet, the second permanent magnets and the first region, and a central portion thereof is formed between the first permanent magnet and the first region, and entrance/exit portions of the q-axis magnetic flux path formed between the second permanent magnets and second regions provided on both circumferential sides of the first permanent magnet and having a low magnetic permeability with generally the same width. |
