Abstract The hardware design process of the variable frequency speed regulation system for sensorless BLDCM
was presented. The main circuit implementation scheme based on IPM-PS21865 was given and the hardware design of
auxiliary circuit and controller which used TMS320LF2407A DSP as the core pleted. Experimental results
showed that the system has high control precision,safe and stable operation and good speed adjusting performance can
be achieved. Therefore,it has good prospects for applications.
