초록

Motor drive has used in many industrial application. In this situation the motor performance reliability has been more and more important. Sensor fault is critical defect to motor performance especially current sensor. Therefore this paper is dealing with SPMSM current sensorless algorithm in Luenberger estimation method with only a phase current information for current sensor fault situation. And the algorithm is verified with experimental results.
