摘要： The present invention provides a linear motor driven elevator apparatus which enables a decrease in the thrust variation at the passage of primary windings of a linear induction motor loaded on a car or a balance weight through joints of secondary conductors and which can prevent an unpleasant impression from being given to the passengers.In the elevator apparatus, each of the connections of the secondary conductor members of the linear induction motor serving as a drive source for vertically driving an elevator car has a structure in which each of the secondary conductor members is notched to about half of the thickness thereof, and the notch portions are superposed. The length of each of the notch portions is set to a value greater than the pole pitch of the primary windings of the linear induction motor, and the set heights of the joints are different from each other.

摘要： A system for controlling operation of an elevator car door includes a torque command output device for outputting a torque command for controlling a car door driving motor on the basis of a difference between a speed command commanding the operating speed of the motor and the actual speed of operation of the motor, a door position detector for detecting the position of the car door in terms of the number of pulses in a pulse train produced by an encoder connected to the motor, and a memory for storing torque limit values as a function of the door position. The system also has a controller which reads the torque limit value corresponding to the car door position detected by the door position detector. The controller then compares the read torque limit value with a torque command output from the torque command output device and generates a reversing instruction to be given to the motor upon determining that the torque command is not smaller than the torque limit value. An obstruction of the door is sensed as a rise in the torque command so that the car door is reversed to ensure safety.
