Abstract (en)
A brake apparatus for an elevator includes a brake apparatus main body having a brake coil, and a discharge circuit connected in parallel to the brake coil. The brake apparatus main body serves to apply a braking force to a car by stopping the supply of electric power to the brake coil and release the braking force applied to the car by supplying electric power to the brake coil. The discharge circuit attenuates a current of the brake coil when the supply of electric power to the brake coil is stopped. In addition, the discharge circuit has a discharge parallel part that includes a resistor, and an overvoltage absorber which is connected in parallel to the resistor for maintaining a voltage impressed on the resistor within a predetermined range.
