摘要： A motor includes a stator and a rotor. The stator is configured by winding a coil around a stator core which includes a salient-pole core. The rotor has a rotor core made by laminating thin and highly permeable iron sheets. The rotor core has multiple permanent magnet embedding holes, and a permanent magnet is embedded in each of the permanent magnet embedding holes. A cross-section of the permanent magnet is a rectangle with a long side in a rotating direction and a short side perpendicular to the long side. A cross section of the permanent magnet embedding hole is formed by an embedding hole's long side corresponding to the long side and an embedding hole's short side corresponding to the short side. The embedding hole's short side has a first protrusion and a flat portion. The embedding hole's long side to an inner diameter side has a second protrusion on its both ends.
