A kind of dental plants tooth motor, includes that plug group, rotor set, stator pack, coil group, motor housing are formed, wherein in the fixed dress what plug group of aforementioned magnetite system, and engaged with the rotor set, among stator assembling what motor housing. Utilize 360 degree of suction effects of the magnetite and the rotor set, when operating the rotor set what, it is able to maintain and is rotated in same plane, vibration Bi Ti Noboru rotor quality balance and improvement eccentricity issues when rotor set rotates caused by avoiding because of centrifugal force, and then increase motor balance and reduce tooth mill vibration, raising motor bearing service life, tooth mill service life.一種牙科用植牙馬達，包括有插頭組、轉子組、定子組、線圈組、馬達外套所組成，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之中。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。
