Patent number: 11960253Abstract: A system and a method for parameter optimization with adaptive search space and a user interface using the same are provided. The system includes a data acquisition unit, an adaptive adjustment unit and an optimization search unit. The data acquisition unit obtains a set of executed values of several operating parameters and a target parameter. The adaptive adjustment unit includes a parameter space transformer and a search range definer. The parameter space transformer performs a space transformation on a parameter space of the operating parameters according to the executed values. The search range definer defines a parameter search range in a transformed parameter space based on the sets of the executed values. The optimization search unit takes the parameter search range as a limiting condition and takes optimizing the target parameter as a target to search for a set of recommended values of the operating parameters.Type: GrantFiled: December 28, 2020Date of Patent: April 16, 2024Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Po-Yu Huang, Chun-Fang Chen, Hong-Chi Ku, Te-Ming Chen, Chien-Liang Lai, Sen-Chia Chang

Patent number: 11139713Abstract: A brushless motor stator includes a stator core and a stator winding. The stator core has a stator frame, a coil carrier and multiple pole shoes. The coil carrier is mounted on one of the two openings of the stator frame and has a tooth base and multiple teeth. The teeth are formed on a top surface of the tooth base. The pole shoes are formed on the inner annular surface of the stator frame. The stator winding is formed by using a single wire to wind around the tooth base, the multiple teeth and the multiple pole shoes, and passing through three of the multiple slots of the coil carrier to extend beyond the outer annular surface of the stator frame to form three extended segments to correspond to U-phase, V-phase and W-phase output terminals of a motor, thereby reducing the number of spot-welding on a wiring board.Type: GrantFiled: June 3, 2019Date of Patent: October 5, 2021Assignee: Techway Industrial Co., Ltd.Inventors: Hong Fang Chen, Wei-Ting Chen, Wei Lin Hsu, Ju-Sheng Cheng

Publication number: 20070172723Abstract: A lithium-ion battery protector device is composed of a lithium-ion battery which is serially connected to form a lithium-ion battery set. When the throttle signal of lithium-ion battery reaches to a low potential, the battery protector will enter into a protection mode. When the throttle signal of lithium-ion battery reaches to a stable potential, the throttle signal of the lithium-ion battery will be the same as that of a receiving device. The battery protector can monitor a charging and discharging status of each lithium-ion battery through a light indicator and a control circuit. When the receiving device receives the throttle signal of lithium-ion battery, the magnitude of throttle signal of the receiving device can be effectively controlled through an automatic identification of the throttle signal by the battery protector, such that the lithium-ion battery will not be excessively charged and discharged.Type: ApplicationFiled: January 20, 2006Publication date: July 26, 2007Inventor: Hong-Fang Chen
