Advanced sensorless drive technique for multiphase BLDC motors Conference Paper

abstract

• The main purpose of this paper is to develop a new position sensorless drive method for multi-phase brushless DC (BLDC) motors. A BLDC motor with higher number of phases has several advantages. It can reduce the Ampere-turns and torque pulsation and increase the efficiency and iron utilization. Also, it is well used for fault tolerant motor drive systems as in military applications. With the developed speed-independent, new position information that is computed in a microprocessor, highly accurate sensorless operation can be realized for multi-phase BLDC motors. The operational principle of the proposed sensorless drive for multi-phase BLDC motors is theoretically analyzed and the performance is demonstrated by computer simulations and experiments in detail. 2004 IEEE.
