ABSTRACT:
A machine model estimating device of an electric motor control apparatus having an electric motor for driving a load machine, a rotation detector for detecting a rotating angle of the electric motor, and a servo control device for controlling the electric motor. The machine has a calculating device for outputting an operation command signal for operating the electric motor to the servo control device, and frequency characteristic equations for a rigid body model and an N-inertia model, N being an integer which is equal to or greater than 2, which are previously input to the calculating device. The calculating device includes a frequency characteristic measuring section, a frequency characteristic peak detecting section, an attenuation estimation value analyzing section, a frequency characteristic error calculating section, and a machine model deciding section.
