Model Selection Information (Push Force) RCP2 Series Rotary Output Torque The output torque will decrease as the rotating speed increases. Use the graphs below to check if the required operating speed and torque can be achieved. 2.0 RCP2-RTB/RTC (Gear ratio 1/20) 2.0 RCP2-RTB/RTC (Gear ratio 1/30) Output torque (N•m) 1.5 1.0 0.5 Output torque (N•m) 1.5 1.0 0.5 0 0 100 200 300 400 500 Rotating speed (°/sec) 600 0 0 100 200 300 400 Rotating speed (°/sec) Allowable Inertial Moment The allowable inertial moment of a rotatable work varies depending on the rotating speed. Check the operating conditions and the inertial moment of the work to be rotated (refer to p. 16) to select an appropriate model.

In this case, either the rotating speed or the inertial moment of the work must be reduced. Select an appropriate model from the shape and weight of the load installed on the output shaft by using the figures and tables below as a reference. * The weight that can be rotated varies depending on the rotating speed. (The higher the rotating speed, the less the rotatable weight becomes.) A.

In this case, either the rotating speed or the inertial moment of the work must be reduced. • If the load exceeds the allowable value, the actuator may malfunction, its service life may be shortened, or damage may occur. The load must be set so that the allowable value will not be exceeded. • If a rotating axis is used horizontally, the work structure must be such that the load torque can be minimized.
