  • Patent number: 9601945
    Abstract: An emergency power supply for a traction elevator system utilizes a microprocessor-based control arrangement with pulse-width modulator technology to create an efficient, cost-effective back-up power system for a traction elevator. The microprocessor-based control arrangement is used to sense a power loss, or any type of irregularity in the power supply. Upon sensing some type of power malfunction, the microprocessor-based control arrangement disconnects the elevator system from the main power source and then generates a control signal to initiate the supply of back-up power. Once the elevator electrical system has been recharged and stabilized, the elevator control system will sense that recovery has occurred and will then provide an appropriate speed and direction command to the traction motor drive system.

  • Patent number: 9601969
    Abstract: An apparatus includes a load and a first armature. A first lever mechanically couples the first armature and the load. Motion of the first armature causes the first lever to pivot about a first pivot axis. The apparatus also includes a second armature and a second lever that mechanically couples the second armature and the load. Motion of the second armature causes the second lever to pivot about a second pivot axis. At least one stator is provided for creating magnetic flux for the first and second armatures to interact with, thereby to drive motion of the load. The apparatus also includes a coupling mechanism that couples the first lever and the second lever. The coupling mechanism is arranged to encourage common mode oscillation of the first and second levers and inhibit differential mode oscillation of the first and second levers, thereby to inhibit rocking of the load.
