Mdhibiti wa gari la brashi kutumia kifaa cha kubadili semiconductor kutambua safari ya elektroniki, ambayo hutumia kifaa cha kubadili umeme badala ya commutator ya jadi ya mawasiliano na brashi. Inayo kuegemea juu, hakuna cheche za kusafiri, na kelele ya chini ya mitambo, inayotumika sana katika sauti ya juu, video, vifaa vya elektroniki na vifaa vya otomatiki vya ofisi. By the permanent magnet brushless motor controller, multipolar winding of the stator and rotor position sensor, etc. Position sensing according to the change of rotor position, along a certain sequence of stator winding current converter (By detecting the rotor magnetic pole relative to the position of the stator winding, and in determining the location of the position sensor signal, the signal conversion circuit to control the power switch circuit, after processing according to certain logic relation between winding current Badilisha)。 Voltage ya kufanya kazi ya stator vilima kubadili mzunguko wa umeme unaodhibitiwa na pato la sensor ya msimamo.
