| 简介 |
Provided is a rotor for an inclusive magnet-type synchronous machine with which it is possible to maintain or increase output while effectively utilizing a rare earth magnet serving as a bond magnet. This rotor (R) for an inclusive magnet-type synchronous machine is provided with : a body (1) comprising a substantially columnar or substantially cylindrical soft magnetic material, the body (1) having a plurality of inclusion parts (13), which are closed-ring cylindrical voids curving in a concave shape towards the outer circumference side and extending in the rotary center axis direction, disposed around a rotary center axis (O); and permanent magnets (2) comprising a rare earth bond magnet, formed upon being packed into the inclusion parts. The inclusion parts according to the present invention are characterized in having rectangular parts (131, 132), comprising flat inner wall surfaces extending in the rotary center axis direction and facing each other in parallel, in a section from an outer circumference end nearest to the outer peripheral edge of the body to an inner peripheral end nearest to the rotary center axis of the body. The magnetic flux distribution of the bond magnets, which are formed packed into the rectangular parts, becomes substantially uniform. The bond magnets exhibit a higher magnetic flux density and a reduced demagnetization amount. |
