In this paper, the authors present a novel LabVIEW based indirect position control of Four Switch Three Phase Inverter (FSTPI) fed BrushLess DC (BLDC) motor drives using a Field Programmable Gate Array (FPGA). In this proposed experimental technique the sensorless position detection based on zero crossing points of the line voltage difference measured at the terminals of the motor using virtual instrumentation. The controlled PWM pulses for FSTPI are generated using Xilinx FPGA program. The low cost BLDC drive is achieved by the reduction of switch device count, cost down of control, and saving of hall sensors.
