ELEVATOR CONTROL DEVICE AND ELEVATOR CONTROL METHOD

摘要

Provided is an elevator control device comprising: a hoisting machine (3) that drives the raising and lowering of an elevator car (1) and a counterweight (5) that are arranged inside an elevator hoistway; a brake device (6) that brakes a motor in the hoisting machine (3); and a status monitoring unit (8). The status monitoring unit (8) includes: a brake control unit (9) that, by controlling current to a brake coil, controls the braking force of the brake device (6); an unbalanced torque detector (12) that detects unbalanced torque information; and a detection unit (13) that releases braking by the brake device (6), calculates the electromagnetic attraction force of the brake coil from the time elapsed from release to when the motor starts rotating, and detects the braking capacity of the brake device (6) on the basis of the calculated electromagnetic attraction force and the unbalanced torque information.
