  • Patent number: 9764926
    Abstract: A brake assembly for an elevator includes a brake, a brake operating device and a first brake wire connected to the brake operating device and to the brake, the brake operating device being configured to release the brake by moving the brake operating device and the first brake wire to a first direction. A second brake wire is connected to the brake operating device and to the brake, and the brake operating device is configured to engage the brake by moving the brake operating device and the second brake wire to a second direction.

  • Publication number: 20140203227
    Abstract: An elevator motor includes a rotor with a rotor body carrying a traction sheave as well as a brake surface configured to be gripped by a motor brake. The brake surface of the rotor is provided on a separate brake element which is separated from the rotor body, and the brake element is connected to the rotor body only via spaced apart connections. This solution leads to a reduced noise propagation of the elevator rotor.
