Examining operating status
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:
Examining actuator rotation speed
Calculate the actuator rotation speed [r/min] of the load driven by the FHA-C mini series.
For linear operation, use the rotation speed conversion
formula below:
Select an appropriate reduction ratio from the 30, 50 or
100 series so that the calculated actuator rotation
speed does not exceed the maximum rotational speed
of the FHA-C mini series actuator.
Calculating and examining load inertia moment
Calculate the inertia moment of the load driven by the FHA-C mini series actuator.
Refer to [Apx-2 Calculating inertia moment] (PApx-3) for the calculation.
Based on the calculated result, tentatively select a FHA-C mini series actuator by referring to
[Allowable load inertia moment] (P2-1).
