PROBLEM TO BE SOLVED: To provide a speed controller of an elevator, for restraining vibration of the elevator having the large change of high natural, frequencies, for enabling high-accurate speed control regardless of the change of characteristics of the elevator, and capable of easily adjusting the speed. SOLUTION: A speed controller of an elevator is provided with a car speed command value setting means 1 for setting a car speed command value by receiving a start command of an elevator, for driving a pulley by an electric motor and raising or lowering the car through a rope laid on the pulley, a car vibration detecting means 6 for detecting vibration of the car, and a car speed command value correcting means 20 for correcting the car speed command value set by the car speed command value setting means 1 by a vibration detecting value detected by the car vibration detecting means 6, and the speed of the electric motor is controlled according to the corrected car speed command value. |
