Abstract:

This paper presents a Hall sensor auxiliary circuit, what provided two functions: first is the Hall sensor signal noise filter caused by temperature or EMI; the other is speed calculation. For brushless DC (BLDC) motors, the Hall sensors originally are used to detect rotor position and decide the timing of commutation, but the signal is easily to be influenced. The proposed scheme is combined with a commutation trigger block and a timing latch block to achieve above two functions. This circuit is based on the VHDL language and implemented in FPGA, and then the synthesizing simulation results and experimental results are presented to prove this circuit is workable.
