Examining operating conditions
The actuator generates heat if started/stopped repeatedly or operated continuously at high speed.
Accordingly, examine whether or not the generated heat can be accommodated.
The study is as follows:
Calculate the actuator rotation speed
Calculate the required rotation speed (rpm) of the load driven by the SHA series.
For linear operation, use the rotation speed conversion formula below:
Select an appropriate reduction ratio so that the calculated rotation speed does not exceed the
maximum rotational speed of the SHA series actuator.
Calculating and examining load moment of inertia
Calculate the load inertia moment of the load driven by the SHA series actuator.
Refer to [A-2 Calculating moment of inertia ] (P103) for the calculation.
Based on the calculated result, tentatively select an SHA actuator by referring to [Allowable load
moment of inertia ] (P71).
