The utility model discloses a novel permanent -magnet machine rotor that mixes magnetic circuit, including permanent magnet, rotor core and the setting pivot in rotor core, the permanent magnet includes built -in permanent magnet and surperficial formula permanent magnet, built -in permanent magnet is radial structure, built -in permanent magnet inlays the inside of putting at rotor core, surface formula permanent magnet inlays to be put on the rotor core surface to with built -in permanent magnet formation NULL's magnetic pole, every magnetic pole comprises parallelly connected two kinds of magnetic circuits that combine together with the connection in series -parallel. This neotype beneficial effect does: use this permanent -magnet machine rotor effectively to increase air -gap flux density, improve the sine nature of air gap field, reduce magnetic leakage and core loss, torque ripple when weakening the steady -state operation.
