A variable-frequency control system was designed for the sensor-less brushless motor. The ARM processor and the compact power device FSB50450S were adopted in this system. The position detection of the brushless motor was based on the B-EMF zero-crossing method. After the speed control module and the current regulator module were achieved, the constant speed control module and the constant pressure control module were researched in the pump circulation system. Experimental results were showed that the control system was satisfied for the pump control, and was with practical application prospect.
