Abstract: Dual-channel flux-switching permanent magnet(DC-FSPM)motor is a new class of stator-PM machine with improved reliability.Based on a new digital signal processor(DSP)TMS320F2812,a new full-digital DC-FSPM motor drive was developed,in which adopted a photoelectric incremental encoder.Due to the missing report of Z-signal,position calculation suffers from the accumulated error.A new Z-signal processor circuit was proposed.The experimental results show that the proposed method of position sensor is effective,and this work lays a foundation for the further study of DC-FSPM motor.
