Please refer to the graph on the left
to replace the SGM type with the
SGMJV or SGMAV.
Replace with the SGMAV when the
ratio of load moment of inertia and
rotor moment of inertia is five times or
less, or the load ratio is 60% or more.
Else, replace with the SGMJV.
【 Reference 】
The graph on the left shows the
load ratio when replacing the
SGMAH which is using 70% load with
the SGMJV and SGMAV.
The load ratio increases but the
system is stable because the rotor
moment of inertia of SGMJV is larger.
