Abstract (en)
In an elevator apparatus, braking force on a car is generated by stopping passage of electric current to a brake coil of a braking apparatus, and generation of the braking force on the car is stopped by passing electric current to the brake coil. A brake controlling apparatus has: a first brake controlling means that controls the braking force on the car by adjusting a quantity of electric current that is passed to the brake coil, and a second brake controlling means that can forcibly stop the passage of electric current to the brake coil. The second brake controlling means has a plurality of computing means that separately determine the presence or absence of elevator abnormality based on information from predetermined detecting means, and that perform control that stops the passage of electric current to the brake coil if it is determined that there is an abnormality in the elevator.
