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: The operating temperature TS1 is the maximum value of the operating temperature defined from a safety point of view by the manufacturer of the system for the various components. The temperature point TS1 is in correlation to the pressures PS1+ and PS1-; Name: Max. permissible operating temperature at TS1, room1
