| Abstract: | A new position sensorless control circuit for four-switch three-phase(FSTP) brushless DC motor (BLD-CM) drives is designed based on the digital signal processing SPMC75F2413A.A novel sensorless control with six commutation modes and novel pulsewidth modulation scheme is developed to drive FSTP BLDC motors.The drive circuit in BLDCM is analyzed.The feasibility of the proposed sensorless control for FSTP BLDCM drives is demonstrated by analysis and experimental results. |
