The present invention relates to a brushless electromagnetic motor, which has a rotor set, a stator set, a plug set, a magnet, a motor cover kit and a motor end cap. The said magnet is fixedly fitted in an interior space between said plug and said rotor. After connection of said rotor and said plug, said stator which grasps said rotor was covered by motor cover kit, linking said motor end cap. By virtue of 360 degrees magnetic attraction between said magnet and said rotor, said rotor can be maintained in the same horizontal rotation during operation, in case of vibration due to the centrifugal force caused by the rotation of the rotor, therefore enhancing the mass balance of said rotor, improving eccentricity, consequently increasing the balance of motor, decreasing vibration of the dental handpieces and improving both life span of dental handpieces and bearings of the motor.本發明關於一種電動磁吸無刷磨牙馬達,係包含有一轉子組、一定子組、一插頭組、一磁石、一馬達外套組與一馬達下套組。其中前述磁石係固定裝於該插頭組內,並與該轉子組接合,該定子組裝於該馬達外套組之中,與該馬達下套組接合。利用該磁石與該轉子組的360度吸力效果,使該轉子組於運轉時,能保持在同一平面旋轉,避免因離心力造成轉子組旋轉時的震動,俾提昇轉子質量平衡及改善偏心問題,進而增加馬達平衡及降低磨牙機震動、提高馬達軸承壽命、磨牙機壽命。10‧‧‧插頭組101‧‧‧線圈蓋102‧‧‧外殼上蓋20‧‧‧磁石30‧‧‧轉子組301‧‧‧叉型元件302‧‧‧永久磁鐵303‧‧‧軸心40‧‧‧定子組401‧‧‧定子402‧‧‧線圈組50‧‧‧馬達外套組60‧‧‧馬達下套組
