摘要： A rotor for a rotary electric machine includes a plurality of magnetic poles disposed at intervals in a circumferential direction, on an outer periphery of a rotor core that is a steel sheet stack that has a shaft hole in a central portion thereof configured so that a shaft is passed through and fixed to the shaft hole. The magnetic poles each have two permanent magnets and a magnetic flux suppression hole that regulates flow of magnetic flux from the permanent magnets, and are formed in such a manner that a shape of the magnetic flux suppression hole of at least one magnetic pole is different from a shape of the magnetic flux suppression hole of another magnetic poles, depending on the presence or absence of a positioning portion.

摘要： A rotary electric machine configured with a stator, rotor, and permanent magnets disposed in an inverted V-shape that becomes gradually narrower from a side of a center of rotation of the rotor. The rotor is provided with a plurality of support portions that extend radially about the center of rotation, and gap portions are respectively formed in correspondence with the plurality of support portions at positions spaced by a predetermined distance from an edge portion of the permanent magnets in a flowing direction of magnetic flux between the permanent magnets and the stator. The gap portions are formed to have such a length that causes magnetic saturation during generation of low torque in a low-current state and that causes no magnetic saturation during generation of maximum torque in a high-current state in which electricity at a high current is supplied to the stator coil.

摘要： A plurality of magnetic poles are disposed at intervals, in a circumferential direction, at an outer periphery of a rotor core. Each magnetic pole has a pair of permanent magnets disposed spaced apart from each other in the circumferential direction, and a magnetic flux suppression hole that suppresses flow of magnetic flux and that is formed extending on the inward side in the radial direction, between inner-periphery-side end portions of each permanent magnet. The magnetic flux suppression hole is formed of two first holes respectively communicating with magnet insertion holes into which the permanent magnets are inserted, and a second hole that is formed between the first holes with bridge portions interposed therebetween. An outer-periphery-side end portion of the second hole is positioned further outward than an imaginary straight line that passes through the inner-periphery-side end portions of the pair of permanent magnets.

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.
