Abstract

This paper presents a novel twelve-step sensorless drive scheme for a three-phase brushless DC motor, which combines the traditional six-step 120° and 180° conduction modes and has varied active angular period. The proposed scheme is implemented on a single FPGA-chip. Several experiments for various active angle periods from 124° to 168.75° are undertaken. The experimental results show that the torque constant is larger for the larger active angular period.
