In an upgrade of a machine we will replace an AC motor with a servomotor.
Because we don't know the mechanical specs of the load on the motor, we can only base on the power of the AC-motor.
We have no torque data available of the AC-motor, only Kw and rpm. If we take a servomotor with approximately the same Kw and nominal rpm, can we suppose then that our servomotor has at least as much torque to drive the load?
I also investigated some AC-motors and servomotors, and saw that for AC-motors and servomotors with same Kw and rpm the inertia is about 3-4 times lower for the servomotors.
What impact could this much lower inertia of the servomotor replacing the AC-motor have?
