An elevator device is provided. The elevator device according to an embodiment includes an elevator driving motor, a motor position measuring unit (220) that calculates and transmits the positional value of the motor to the elevator controlling device, a position storage unit (112) that stores the positional value of the motor, a state feedback position controlling unit (111) that receives the positional value of the motor from the position storage unit every first cycle, receives the speed of the motor, and outputs a torque-controlled value to control the motor, a state estimating unit (113) that estimates the speed of the motor based on the torque-controlled value and the positional value every second cycle and transmits the result to the state feedback position controlling unit, a vector controlling unit (114) that generates a current-controlled value based on the torque-controlled value and outputs a voltage-controlled value according to the current-controlled value and the driving current of the motor, and a motor driving unit that controls the driving power source of the motor according to the voltage-controlled value. |
