Abstract
In this paper FPGA is used as the master chip to design the new four-phase sensorless BLDC(brushless direct current) motor control system of automobile engine cooling fan. The design uses BEMF zero-crossing detection algorithm and the hardware modular design approach, while the open-loop circuit adopted to raise the frequency and voltage and the digital phase-shift circuit based on FIPS algorithm are introduced, which makes the whole control system can work in a variety of adverse environment stably and accurately. Experiments show that the system has the good error tolerance for the outside interference and meets the requirements of reliable operation of the motor controller in vehicle engine cooling fan.
