The invention discloses a segmented rotor consequent pole
permanent magnet motor. The segmented rotor consequent pole
permanent magnet motor comprises two segments of rotors, wherein the two segments of rotors are connected in an axial direction of the rotors, a surface of each segment of rotor is provided with multiple convex poles, grooves among the adjacent convex poles are embedded with permanent magnets, a convex pole and permanent
magnet alternating arrangement structure is formed on surfaces of the rotors, the shape of the permanent magnets is in matching with the shape of the grooves, each surface of the permanent magnets and each surface of the grooves realize tight contact, upper surfaces of the permanent magnets and upper surfaces of the convex poles are arc-shaped surfaces,
radian of the upper surfaces of the permanent magnets and
radian of the upper surfaces of the convex poles are identical, all the upper surfaces of the convex poles and all the upper surfaces of the permanent magnets form an integral cylindrical surface, the permanent magnets on the two segments of rotors circumferentially offset for a half electric period angle, magnetizing directions of the permanent magnets on one segment of rotor are identical, and magnetizing directions of the permanent magnets on different segments of rotors are opposite. The segmented rotor consequent pole
permanent magnet motor is advantaged in that disadvantages of a traditional surface-mounted permanent
magnet motor are solved, permanent
magnet materials and protection sleeves are saved, and
magnetization of an end portion of a rotation shaft can be avoided.
