Abstract
Brushless DC (BLDC) motor is attracting much interest due to its high efficiency, good performance and ease of control for many applications. Moreover, reducing of the drive components is more attractive for low cost applications. This paper presents the design and implementation of a reduced-parts BLDC motor drive using the TMS320LF2407A digital signal processor (DSP). Part reducing is achieved by elimination of three Hall Effect position sensors and reducing the number of power switches. The performance of the proposed reduced parts BLDC motor drive is verified via some simulations. Then, hardware and software details of the system are explored. Finally, an experimental system including a BLDC motor, DSP control board, inverter, and rectifier is set up to validate the theoretical results.
