A slotless amorphous ferroalloy electric machine with radial magnetic circuit and a manufacturing method thereof are provided. A stator iron core (21) of the electric machine is a cylinder formed by winding an amorphous ferroalloy strip. A stator winding (22) is integrally in the shape of a cylinder and fixed on the internal cylindrical surface of the stator iron core (21). A metal reinforcing sleeve (25) is fixed on the internal surface of the stator winding (22). A radial air gap (5) is arranged between the internal cylindrical surface of the metal reinforcing sleeve (25) and the external surface of a rotor (3). A rotor iron core (31) is a hollow cylindrical structure made of amorphous ferroalloy material. The inner bore wall of the rotor iron core (31) is provided with keyway (312) used for connecting with a electric machine shaft (6). The radial external surface of the rotor iron core (31) is matched with permanent magnets (32). The permanent magnets (32) are embedded in or sheathed outside the external surface of the rotor iron core (31). With the electric machine, volume and loss are effectively reduced, and efficiency is improved. Processing difficulty of tooth slots is avoided, and man-hours is saved, and processing cost is greatly reduced, thus cogging effect of the electric machine is avoided, and electromagnetic noise is reduced. The electric machine also has the advantages of low eddy current loss, superior high frequency performance, high power density, high efficiency and energy saving. |
