2-3 Examining the operating status
The motor generates heat if started/stopped repeatedly or operated continuously at high speed.
Accordingly, evaluate whether or not the generated heat can be accommodated.
Evaluate as follows:
Examining motor rotational speed
Calculate the required rotational speed (r/min) of the load driven by an HMA series motor.
For linear operation, use the rotational speed conversion formula below:
Check that this rotational speed is less than the max. rotational speed of the HMA series motor.
Calculating and examining load inertia moment
Calculate the inertia moment of the load driven by an HMA series motor.
Refer to [A-2 Calculating inertia moment] (P5-3) for the calculation.
Based on the calculation result, make a tentative selection of an HMA series motor referring to
[Allowable load inertia moment] (P2-1).
