MUMBAI, India, June 6 -- Intellectual Property India has published a patent application (202517005866 A) filed by Shenzhen Jisu Technology Co. Ltd., Guangdong, China, on Jan. 24, for 'motor driving control circuit, portable fan based on high-speed three-phase motor, and portable fan control method.'
Inventor(s) include Zheng, Guanzheng; Gao, Haijun; and Xie, Jiahang.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "Disclosed are a portable fan based on a high-speed three-phase motor and a portable fan control method. The portable fan comprises a control module, a driving module, and a high-speed three-phase motor. The high-speed three-phase motor has a working voltage of 2-18 volts, a working current of 0.1-10 amps, and/or a limited working power of 0.5-100 watts. By means of the driving module, the control module controls the rated working rotation speed of the high-speed three-phase motor on the basis of the working voltage, the working current, and/or the limited working power, so as to reduce the high rotation speed noise of the high-speed three-phase motor and control the wind speed to be within a preset wind speed interval. According to the technical solution, the control module, the driving module, and the high-speed three-phase motor are combined, a solution of a portable fan with high efficiency, low noise, and adjustable wind speed is provided, the portability and the use comfort of the fan are improved by means of the low-voltage driving technology and the control strategy, and the user experience is improved."
The patent application was internationally filed on July 24, 2024, under International application No.PCT/CN2024/107360.
