MUMBAI, India, Oct. 5 -- Intellectual Property India has published a patent application (202517114632 A) filed by Chery Automobile Co. , Ltd. on November 20, 2025, for Rotor Core, Motor Rotor, Motor, And Automobile.
Inventors include Lv, Shun; Hu, Longfei; and Tao, Jun.
The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: The present application provides a rotor core (1), a motor rotor, a motor, and an automobile. A rotor shaft cavity (11), a plurality of first cooling channels (12), and a plurality of first rotor slots (13) are formed in the rotor core (1); the rotor shaft cavity (11), the first cooling channels (12), and the first rotor slots (13) pass through the rotor core (1) in the axial direction of the rotor core (1); the plurality of first rotor slots (13) and the plurality of first cooling channels (12) are distributed at intervals in the circumferential direction of the rotor core (1), separately; all the first cooling channels (12) are located between the rotor shaft cavity (11) and the first rotor slots (13); and all the first rotor slots (13) are communicated with the first cooling channels (12). By means of the arrangement, a cooling medium flowing in the first cooling channels is in direct contact with permanent magnets in the first rotor slots for heat exchange so as to cool the permanent magnets, thereby preventing the risk of demagnetization of the permanent magnets caused by excessive temperature.
