BLDC motor commutation based on DSP builder for FPGA

Motion Control focus on BLDC motors based on hall effect sensors needs a strategy of voltage commutation between their windings. In this paper an alternative of a BLDC motor commutation based on DSP Builder toolbox is presented. The DSP Builder is a tool to FPGA programming in the Matlab/Simulink environment that reduce the programming complexity. The strategy is based on hall effect sensor signals and a bit of direction to generate the signals that enable the gates of MOSFETs. The strategy of commutation has been verified by simulation and experimentation with a BLDC motor.
