  • Patent number: 5896949
    Abstract: An apparatus and method are disclosed for reducing oscillations of an elevator car occurring transverse to the direction of travel. The elevator car is guided by rails and includes guide elements with a predefined range of motion. The apparatus includes a plurality of inertial sensors mounted to a frame of the elevator car and at least one actuator positioned between the elevator car and the guide elements. The inertial sensors measure oscillations transverse to the direction of travel and the at least one actuator is driven according to the output from the inertial sensors to actuate movement in an equal and opposite direction to the oscillations. The at least one actuator includes a drive motor with a stationary motor part coupled to the frame and a moving motor part coupled to the guide elements. The method includes measuring an oscillation occurring transverse to a direction travel and driving at least one actuator positioned between the car and the guide elements.
