Patent number: 8525465Abstract: A feedback switching device and a method allow a drive control loop for a servo motor to actively switch the feedback mode in accordance with the rotating speed of the servo motor. When the servo motor is under a high speed operation, a sensorless position estimation feedback technology is used as the feedback mode; on the other hand, when the servo motor is under a low speed operation, the switching mode is automatically switched to a position sensing feedback technology. Therefore, the development needs for multi-function, high performance and low cost in the field of the servo motor control are met, and the conventional problem is solved that, when being applied to a servo driving system having a wide speed range, the single use of the position sensing feedback technology or the sensorless position estimation feedback technology fails to satisfy the application for a wide speed range.Type: GrantFiled: December 9, 2010Date of Patent: September 3, 2013Assignee: Industrial Technology Research InstituteInventors: Kuo-Lin Chiu, Chia-Min Ting, Hsin-Hung Chou

Patent number: 8203295Abstract: A method for controlling starting of a motor is described, which is mainly applicable to estimate a possible initial position of a rotor of a motor by detecting a rotor rotation signal of the motor, and find out a most possible initial position of the rotor after making statistics. In the method for controlling the starting of the motor, a starting angle position region of the motor is calculated simply by using the rotor rotation signal of the motor, without additionally arranging a Hall sensor, so as to save a cost of a Hall device and an assembling cost. Furthermore, accuracy for estimating the starting position region can be increased according to an accuracy specification of products, thereby achieving a high flexibility.Type: GrantFiled: February 16, 2010Date of Patent: June 19, 2012Assignee: Industrial Technology Research InstituteInventors: Chia-Min Ting, Hsin-Hung Chou, Kuo-Lin Chiu
