Abstract: PROBLEM TO BE SOLVED: To provide an automatic fine tuning, at a site, of the rotor time- constant parameter of a motor in a field-oriented driving device without need of removing or separating the motor from an elevator system. SOLUTION: An elevator control apparatus 7 is provided with a logic 48. The logic 48 raises and lowers and elevator so as to, it computes a rotor time constant τR for a field-oriented current regulator/a motor driving device 20, it computes an average DXDERR of sign adjusted error signals for the raising, lowering and running operation of the elevator, it changes the time constant τR, and it decides the value of the time constant τR. By the value of the time constant τR, the average of DXDERR with reference to the raising, lowering and running operation of the elevator becomes equal to zero within a prescribed tolerance. IN addition, instead of computing the average of DXDERR, the value of the time constant τR at which the average of DXDERR becomes equal to zero within the prescribed tolerance is decided. As a result, a single elevator run operation can be used.

Abstract: PROBLEM TO BE SOLVED: To obtain force keeping a brake and closing/opening of an elevator door, satisfying safety standards, independent of a linear electric motor, in relation to an elevator door operating device. SOLUTION: A friction material brake pad 11 is pressed against a surface of a door hanger 24 by a push type solenoid 19, and when no brake action is required, a brake shoe is pulled to be separated from the door hanger by a spring means. When a door power source is supplied, always a current is carried in the solenoid 19, and in the case of moving a door, always resultant force is placed in a neutral condition by force generated by a current supplied to a linear electric motor. When the power source is tripped during operation of the door, an instantaneous brake is executed by instantaneously operating the solenoid 19.

Abstract: When an elevator is running, the car door 27 is locked in the closed position by a brake shoe 12 which engages the edge of the door hanger 24 in response to a push-type solenoid 19 overcoming the force of a spring. When the door is not closed, a friction brake pad 11 contacts the door hanger surface to hold the door open for passenger boarding or to stop the door in case of failure of door operator power while the door is in motion.

Abstract: A coupling for causing an elevator car door (13) to engage an elevator hoistway door (48) includes a pair of vanes (33,34), each end of each vane being pivoted on a link (22,23) connecting it with the other vane, the links being disposed for rotation between said two vanes on the elevator car door thereby forming a parallelogram. The vanes extend vertically between four rollers (40-43) which rotate about horizontal axles (44-47) disposed at the top of the hoistway door, and which provide rotationally stiff coupling. A solenoid actuator (14) can move one vane up to cause the parallelogram to shrink into an uncoupled position. When the actuator is energized, a spring (49) causes the parallelogram to spread so that the vanes are wedged between the rollers and the two doors are coupled together.

Abstract: 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.

Abstract: An elevator car door 17 is moved by a variable voltage, variable frequency linear induction motor which is driven in an 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.

Abstract: A linear motor for operating an elevator door is energized using a bang-bang control strategy (10) wherein three-phase AC utility mains (16) are connected (29) directly to the linear motor primary (14) by means of a motor control (12) in response to control signals (26) provided under the direction of a control strategy (10), which may be microprocessor-based. Commands (24) from an elevator controller to open/close the elevator door cause the system to operate the doors and a sensor (22) provides feedback (28) by means of which the control (10) is able to determine switch points for switching the AC mains.
