Abstract: The BLDCM keeps the merits of the traditional DC motors, and also has the AC motors’ excellences, such as simple construction, operational reliability, maintainable feature. This paper introduced the fundamental principles and control characteristics and summarized some new detecting position teniques based on the documents about sensorless BLDCM’s control strategies domestic and overseas. At the same time, the strength and weakness of these new detecting position techniques were discussed. Finally, the development tendency of BLDCM’s control strategy was given out.
