MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202517124207 A) filed by Envision Energy Co. Ltd., Jiangsu, China, on Dec. 9, 2025, for 'permanent magnet generator.'
Inventor(s) include Huang, Qian; Zhao, Gang; Cong, Xiaojie; and Xu, Jianhua.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a permanent magnet generator, comprising: a base (1); a stator (2) having an internal ventilation duct, wherein the outer circumference of a pressing ring of the stator (2) is in interference fit with the base (1) by means of shrink-fitting, thus creating a circumferential air duct between the base (1) and the outer circumference of a core of the stator (2); a rotor located inside the stator (2), the rotor being provided with a rotor magnetic pole (4) having a finned ventilation duct; and coolers (6) arranged at the top of the base (1). Compared with the prior art, the design of the present invention uses a novel air-water cooling method in which cooling water circulates outside of the generator, and air circulates inside the generator; the pressure head for circulation inside the generator is provided by means of the rotation of the rotor having the finned ventilation duct, while a top drive fan at the top of each cooler further provides kinetic energy for an internal circulation air path."
