Patent number: 9071184Abstract: A motor driving system is disclosed having a control device 4A for controlling a synchronous motor 1, the control device 4A comprising a sensorless control algorithm device 20 that includes an abnormality determining device 25 for determining abnormality of the algorithm based on a magnetic pole position error estimated value of the motor 1. When the abnormality determining device 25 has determined abnormality of the algorithm, the control device 4A controls a power converter 2 using a magnetic pole position detected value detected by a magnetic pole position detector 30 attached to the motor, in place of using a magnetic pole position estimated value. This motor driving system can guarantee reliability of the sensorless control algorithm device 20 while assuring safety. Safety of electric vehicles is enhanced by installing the motor driving system that has been guaranteed reliable.Type: GrantFiled: July 16, 2013Date of Patent: June 30, 2015Assignee: FUJI ELECTRIC CO., LTD.Inventors: Takeshi Kuroda, Akio Toba
