Oscillation torque
Web1. For a simple motor with a two-pole armature, if θ A is the armature angle, and θ S is the stator's electrical angle, and a motor with a sinusoidal back-EMF, then the torque is going to be k T I sin θ A − θ S, where k T is the motor torque constant and I is the armature current intensity. So if the motor is turning a constant speed, and ... Torsional vibration is angular vibration of an object—commonly a shaft along its axis of rotation. Torsional vibration is often a concern in power transmission systems using rotating shafts or couplings where it can cause failures if not controlled. A second effect of torsional vibrations applies to passenger cars. Torsional vibrations can lead to seat vibrations or noise at certain speeds. Both reduce the comfort.
