Background The brushless motor winding, three bundles of coils wound on a motor stator, generates a magnetic field after being electrified and pushes a rotor to rotate, and the existing brushless motor winding mainly takes a distributed or conventional concentrated winding, so that the quick response and the high efficiency and the low loss are difficult to be considered; The conventional scheme is to improve response, reduce inductance, easily cause copper loss and heating, and increase turns and inductance when pursuing low loss, so that dynamic response is slow and high-frequency loss is increased. Meanwhile, the traditional winding groove has low full rate, long end and large harmonic wave, further aggravates loss and response lag, and cannot meet the dual requirements of high dynamic and high efficiency of scenes such as servo and electric tools.
