    摘要： An electronic motor drive produces a required motion profile for an elevator door operator actuated by a three-phase, line-powered linear induction motor (LIM) by means of an array of TRIAC switches producing selected forces from the LIM. The TRIAC drive is capable of producing acceleration, deceleration or free coast in either the open or close direction of door operation. When controlled by an algorithm such as a "time-optimal switch point" or "bang-bang" control, the TRIAC drive produces the required motions from the linear induction motor for elevator door operation. The motor windings may be switchable between delta and wye hookups to provide two distinct thrust levels. Phase angle modulation may be used to provide finer control of thrust. The linear motor may be a 12-slot arrangement having four poles and three phases and arranged with flux emanating from the stationary primary (on the car) to a stationary backiron part of the secondary also mounted on the car, wherein the flux passes through a movable copper part of the secondary attached to the elevator door and passing between the primary and the backiron.

    摘要： A coupling for causing an elevator car door to engage an elevator hoistway door includes a pair of vanes, each end of each vane pivoted on a link connecting it with the other vane, the links being disposed for rotation between said two vanes on an elevator car door thereby forming a parallelogram. The vanes extend vertically between four rollers which rotate about horizontal axles disposed at the top of the hoistway door, and which provide rotationally stiff coupling. A solenoid actuator can move one vane up to cause the parallelogram to shrink, into an uncoupled position. When the actuator is disenergized, a spring causes the parallelogram to spread so that the vanes are wedged between the rollers and the two doors are coupled together.

    摘要： An elevator car door is moved by a variable voltage, variable frequency linear induction motor which is driven open current loop to achieve a desired velocity profile indicated by an incremental linear encoder, with washed out proportional and integral gain. A magnetizing current insufficient to overcome the weight of the door is added in quadrature with the linear force current, and frequency is determined open loop in a predetermined fashion. Pulse width modulation voltage control signals are utilized to apply fixed voltages of correct polarity through a low pass three phase filter to the windings of the motor for correct intervals of time so as to synthesize desired sinusoidal winding currents. A boost of current is provided following each zero crossing of the sinusoidal winding currents to overcome lags therein. A ramp down of voltage avoids dropping the door at the end of door opening and door closing.

    摘要： A linear motor is used to actuate an elevator door in response to a control signal for counteracting rotational torque caused by a variable-length moment arm about the center of gravity of the door by varying the magnitude of a linear force exerted on the door acting through a fixed-length moment arm about the center of gravity of the door for providing an opposing rotational torque, thereby counteracting the rotational torque caused by the normal force. The first and second rotational torques may be controlled to decrease and increase linearly as the door goes through its motion. In this way, the velocity profile varies in a curve similar to one side of the major axis of an ellipse. The normal force may be provided so as to levitate the door to reduce gravitational forces acting on door rollers. The control may be carried out in an open- or closed-loop fashion.

    摘要： An elevator system has a plurality of elevator cars traveling upwardly in one hoistway and downwardly in an adjacent hoistway, the cars being propelled in a series of overlapping segments, each segment including a pair of couplers roped to counterweights and driven by elevator traction machines. A variant uses a closed loop rope with a pair of couplers to transfer elevator cars from a counterweighted coupler of one segment to a counterweighted coupler of an adjacent segment. An upper passenger landing moves cars on overhead trolleys and a lower passenger landing moves cars on dollies to take them from a hoistway through unloading and loading stations and back to another hoistway. The elevator car roller guides are releasable to permit lateral movement of cars to and from landings. A latched spring buffer and/or a LEM decelerate and accelerate unbalanced counterweights.
