Description: In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear. ; Name: crit. speed
Description: Speed of rotation at which the frequency of vibration (or its multiples) corresponds to the rotor resonant (lateral or torsional) ; Name: Critical speed
Description: Value indicated by the manufacturer of the device which arises from measurements which have been found out under fixed conditions and rules for the tension which can be laid out to electrical operating supplies under consideration of the use conditions and on which the different product-specific testings refer; Name: Rated input voltage
