Motor sikat ditetapkan oleh pengontrol pada waktu yang tepat untuk listrik koil fase motor, untuk menghasilkan medan magnet yang berputar, rotor motor berputar dengan medan magnet yang berputar. When the hall element in the N pole and s pole is different when the potential, the center hall element from a N pole through a magnetic boundary of magnetic steel enters another s pole, just at the moment through a magnetic boundary, hall element instead of potential output, with the potential to control circuit of the controller, the brushless motor flux of coil current direction change, so as to achieve the purpose of motor electronic commutation, when reversing the center line of the hall element and coil reversing the position of Garis tengah tepi harus menjadi kebetulan.
