Patent number: 11921474Abstract: A virtual metrology method using a convolutional neural network (CNN) is provided. In this method, a dynamic time warping (DTW) algorithm is used to delete unsimilar sets of process data, and adjust the sets of process data to be of the same length, thereby enabling the CNN to be used for virtual metrology. A virtual metrology model of the embodiments of the present invention includes several CNN models and a conjecture model, in which plural inputs of the CNN model are sets of time sequence data of respective parameters, and plural outputs of the CNN models are inputs to the conjecture model.Type: GrantFiled: May 25, 2021Date of Patent: March 5, 2024Assignee: NATIONAL CHENG KUNG UNIVERSITYInventors: Fan-Tien Cheng, Yu-Ming Hsieh, Tan-Ju Wang, Li-Hsuan Peng, Chin-Yi Lin

Patent number: 9006953Abstract: A stator assembly structure for an axial flux electric machine is designed. The back iron for each silicon steel disk stator is formed into a specific structure with tooth-like protrusions for allowing the same to be integrated with the disk-type stator seat, while the disk-type stator seat is made of a material suitable for casting or mold forming. A coil is mounted on the disk stator, and a stator assembly is achieved by integrating the stator, the coil and the stator seat. The stator and the disk-type stator seat of the stator assembly are manufactured by using a one-piece cast or one-piece mold forming method so as to enable the contact surfaces of the stator and the stator seat to engage with each other even more tightly, and consequently enable the heat generated from the coil to be transmitted rapidly from the disk stator to the disk-type stator seat.Type: GrantFiled: July 30, 2012Date of Patent: April 14, 2015Assignee: Industrial Technology Research InstituteInventors: Tseng-Te Wei, Shian-Hsuan Huang, Huan-Lung Gu, Shih-Ming Lo, Li-Ju Cheng

Patent number: 8541922Abstract: A magnetic transmission assembly is adapted to integration with a motor or generator. The magnetic transmission assembly includes a rotor, a stator, and a magnetically conductive element. The rotor and the stator are sleeved coaxially and respectively have R and ST1 pole pairs. The magnetically conductive element is located between the rotor and the stator, and has permeable regions. When the magnetically conductive element is actuated, the magnetically conductive element selectively enables PN1 or PN2 permeable regions to be corresponding to the rotor and the stator. The permeable regions corresponding to the rotor and the stator interact with magnetic fields of the R and ST1 pole pairs to generate a predetermined variable-speed ratio. The magnetic transmission assembly can be integrated into the motor, so as to improve the drive power density.Type: GrantFiled: October 14, 2010Date of Patent: September 24, 2013Assignee: Industrial Technology Research InstituteInventors: Ming-Tsan Peng, Li-Ju Cheng
