Torque motor
In the high-speed machining center, the swing of the rotary table and the swinging and turning of the fork-shaped spindle head have been widely implemented using a torque motor. A torque motor is a synchronous motor whose rotor is directly fixed to the component to be driven, so there is no mechanical transmission component, and it is a direct drive like a linear motor. The angular acceleration that can be achieved by a torque motor is six times higher than that of a conventional worm gear, and the acceleration can reach 3g when swinging a forked spindle head. Due to the extremely high static and dynamic load stiffness of the torque motor, the positioning accuracy and repeatability of the rotary and swing axes are improved.
