Abstract: A brushless electromagnetic motor, preferably for use in dental handpieces, has a rotor set, a stator set, a plug set, a magnet, a motor cover kit and a motor end cap. The 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 the motor cover kit, linking said motor end cap. By virtue of 360 degrees of 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.
