Provided is an elevator device using magnetic-pole position estimating control, which is capable of realizing high landing accuracy even in a stopped state and in a super-low speed operation state. The elevator device using a magnetic-pole position estimating method, for estimating a magnetic-pole position by using an induced voltage generated by rotation of a motor of a hoisting machine (11) to perform running control on a car driven by the rotation of the hoisting machine, includes: a detector (32) provided outside the hoisting machine, for detecting a position or a speed of the car; and a control section (20) for determining whether or not the car is in a switched running state according to a running speed of the car or a current position of the moving car, for performing the running control on the car by using the magnetic-pole position estimating control method when it is determined that the car is not in the switched running state, and for performing the running control on the car based on results of detection by the detector when it is determined that the car is in the switched running state. |
