Magnetism-concentrated pole-shoe-shared permanent magnet motor

The invention provides a magnetism-concentrated pole-shoe-shared permanent magnet motor relating to the technical field of permanent magnet motors and solving the problems of low power density, small torque and low response speed of a motor. The permanent magnet motor comprises a stator, a rotor and a plurality of magnetic poles, wherein each magnetic pole comprises two permanent magnets and a pole shoe, the outer side surfaces of the two permanent magnets are respectively engaged with the inner wall of the stator, the inner side surfaces of the permanent magnets are respectively engaged withthe pole shoe, and neighboring sides of the two permanent magnets have same polarity; the edges of the inner side surfaces of the two permanent magnets are connected, and an included angle between the inner side surfaces of the two permanent magnets is less than 180 degrees; the area of the pole shoe surface of the pole shoe is less than the sum of the areas of the inner side surfaces of the two permanent magnets, and an air gap is arranged between the pole shoe surface of the pole shoe and the circumferential surface of the rotor; and a side line of the radial sections of the permanent magnets, facing to one side of the neighboring magnetic poles, is a straight line, and a side line facing to one side of the other permanent magnet in the same magnetic pole is a fold line or curve. The motor provided in the invention has the advantages of high power density, large torque and high response speed.
