A unified definition for dampingtorquecoefficient of synchronous machines is proposed in this paper according to the principle of synthetic damping coefficients deduced from the Lyapunov Theorem.
Under the assumption of constant torquedampingcoefficient, the step response of an ultrasonic motor is obtained from the moment equation of the rotor, and also the property is deduced.
