2.3. Inertia (Momentum)

2.3. Inertia (Momentum)

 

This is the inertia moment of the load itself. Assuming that the 3 axes, x, y, and z, are rotating based on the center, this refers to the sum of the each weight distributed on the load times the distance from the rotating axis cubed. The inertia will be decided according to the weight distributed on the circumference of a shaft. Its value will become larger as the mass of the load is distributed more distantly from the rotating shaft. The unit to be applied for the x, y, and z axes is kgm2.
