Patent number: 11531067Abstract: A motor demagnetization detection method includes the following steps. The speed of a motor is calculated according to the rotation angle of the motor. When determining that the motor respectively maintains a first and second steady state according to the speed, the three-phase current values of the motor are received to obtain first and second steady-state data. An equivalent magnetic flux is calculated according to the first and second steady-state data. The motor is repeatedly driven to maintain the first and second steady states, the first and second steady-state data are updated according to the three-phase current values, and the equivalent magnetic flux is again calculated to generate equivalent magnetic fluxes. A magnetic flux change is calculated according to equivalent magnetic fluxes. A demagnetization warning is issued according to a comparison of the magnetic flux change and a demagnetization warning value.Type: GrantFiled: June 30, 2021Date of Patent: December 20, 2022Assignee: DELTA ELECTRONICS, INC.Inventors: Shao-Kai Tseng, Jen-Chih Tseng, Sheng-Han Wu

Patent number: 10120688Abstract: A data processing system includes a control register, a program counter and a controller. The control register is used to store a level status of an execution flow and at least one return address. When the controller reads a block call instruction while a level status of the execution flow has an initial value, the controller stores a return address of the block call instruction in the control register, increments a value of the level status, and redirects the execution flow to a target address indicated by the block call instruction. When the controller reads a block return instruction and the value of the level status is not equal to the initial value, the controller decrements the value of the level status. If the value of the level status becomes equal to the initial value, the controller redirects the execution flow to the return address.Type: GrantFiled: November 15, 2016Date of Patent: November 6, 2018Assignee: Andes Technology CorporationInventors: Jen-Chih Tseng, Hong-Men Su, Chuan-Hua Chang
