A sensor less brushless DC motor controller based on Actel Fusion mixed- signal FPGA

For the Actel Fusion mixed-signal FPGA development board, this paper introduced a kind of brushless motor sensorless controller based on the Actel Fusion FPGA, with the three-phase BLDC drive circuit, achieving the continuous tone rate and jitter-free starts and stops of DC motor of the sensorless brushless, the controller has much benefits includes high integration, performance, stability and anti-interference ability.
