Simulation and implementation of sensored control of three-phase BLDC motor using FPGA

Three-phase BLDC motors are widely used for industrial applications that require medium and very high speeds and it is mostly preferred for electric vehicles as it provides high efficiency, low maintenance, long life, low weight and compact construction. This paper presents the implementation of sensored control of three-phase brushless DC motor using FPGA. The commutation is implemented using FPGA and it receives hall sensor output from BLDC motor (1KW) and generates the gate pulses which drive the IGBT switches of the three-phase inverter. A model of the BLDC drive is simulated in MATLAB and the sensored control is implemented on a FPGA platform. The simulation results are verified experimentally.
