Abstract
The present disclosure is in the field of surgical instrument, in particular drills used by surgeons and or dentist, or surgical robots. It is known that a motor generates a torque during rotating accelerations and decelerations. Accelerations and sharp brakes from powerful motors also generate torques to be countered by the surgeon wrist, or the robot chassis. In order to solve this problem, there is proposed a surgical power motor. The motor is made of two rotating parts, rotating in opposed directions, and further includes an inverter to link one rotating part with the other rotating part, each rotating part producing the similar acceleration torque and at least one being powered either by an electric or pneumatic source.
