Ang brushless motor ay itinatag ng controller sa naaangkop na oras para sa koryente ng coil phase coil, upang makabuo ng isang umiikot na magnetic field, ang motor rotor ay umiikot sa umiikot na magnetic field. 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 Ang pagbabalik sa posisyon ng linya ng sentro ng gilid ay dapat na isang pagkakaisa.
