摘要： A motor control device includes an inverter driving an electric motor, a vector controller determining an output frequency and a command output voltage to drive the inverter, a speed controller determining a torque command value, a current command calculation unit and an inertia moment estimation unit obtaining a load torque estimate value and estimating inertia moment that is a combination of inertia moment of a motor rotor and inertia moment of a load apparatus, based on a deviation between an acceleration/deceleration torque output value obtained by subtraction of the load torque estimation from motor torque and an acceleration/deceleration torque estimate value obtained by multiplying a variation amount in the speed estimate value per unit time by an inertia moment estimate value. The speed controller is configured to be capable of adjusting a control parameter based on an inertia moment estimate value estimated by the inertia moment estimation unit.
