摘要： A linear induction motor for an elevator which includes a secondary, stationary element having a body formed with a plurality of iron-core mounting holes arranged longitudinally of the body at a certain interval, and iron cores disposed in the holes. The stationary, secondary element allows magnetic flux flowing therethrough to pass through the iron cores, thereby reducing the dimension of the total magnetic gap in the motor. Furthermore, the combination of the iron cores in which eddy currents flow with difficulty and the body along which eddy currents tend to flow makes it possible to reduce the ineffective eddy currents.

摘要： A linear motor elevator includes: a multitude of primary side coils mounted on the hoist way along the whole hoist path, and vertical columns of permanent magnets constituting the secondary side magnets mounted on the elevator car. The polarity of the permanent magnets alternate both horizontally across the columns and vertically along respective columns. When the elevator car is displaced horizontally in a direction perpendicular to the hoisting direction of the elevator car, a circulating current producing a magnetic flux that counterbalances the variation of the flux caused by the displacement flows through each primary side coils opposing the permanent magnets on the elevator car. Thus, the position of the elevator car within the hoist way is automatically adjusted in accordance with the null-flux method.

摘要： A linear motor elevator includes permanent magnets 4 mounted on a pair of wing-shaped support members 21 secured on and projecting sideways from the right and the left side walls 3a of the elevator car 3. The polar axes of the permanent magnets 4 are arranged in the direction of the thickness of the support members 21, such that both the north and the south poles of the permanent magnets 4 are exposed on the front and the back surface of the support members 21 and hence are utilized effectively for producing driving force (thrust) for the elevator car 3. Each one of the right and the left side coils 20a and 20b of the primary side coils 20 for forming vertically translating magnetic field is bent at the middle to form two horizontally extending branches, such that the primary side coils 20 sandwich the permanent magnets 4 across predetermined gaps in the direction of polar axes of the permanent magnets 4, when the elevator car 3 passes by the primary side coils 20. Thus, the strong attractive force acting on the permanent magnets 4 from the primary side coils 20 does not act on the cage structure of the elevator car 3.
摘要翻译：线性马达电梯包括安装在一对翼形支撑构件21上的永磁体4，永磁体4固定在电梯轿厢3的右侧壁3a和左侧壁3a的侧面上并从其侧面突出。永磁体4的极轴布置在支撑构件21的厚度的方向，使得永磁体4的北极和南极都暴露在支撑构件21的前表面和后表面上，因此有效地用于产生驱动力（推力）用于电梯轿厢3.用于形成垂直平移磁场的初级侧线圈20的左右线圈20a和20b中的每一个在中间弯曲以形成两个水平延伸的分支，使得初级侧线圈当电梯轿厢3通过一次侧线圈20时，20将永磁体4夹在永磁体4的极轴方向上的预定间隙上。因此，强力从初级侧线圈20作用在永磁体4上的反作用力不会对电梯轿厢3的保持架结构起作用。

摘要： A control apparatus for an elevator according to this invention comprises a signal setter for setting a new value instead of a value of great variation when at least one signal at the present time among a transmission reference speed command signal transmitted to a speed controller through a transmission interface, a cage speed signal, and a controlled variable based on these signals greatly varies as compared with the time-serial value of the corresponding signal detected in the past.In this invention, the signal setter stores a value at the present time and also stores serially past values with respect to time as to the transmitted reference speed command signal, the cage speed signal, or the controlled variable based on these signals, and it sets the new value not greatly varying, as a present value if the value at the present time greatly varies in view of the past serial values of the corresponding signal. Accordingly, even if any of the transmission interface, cage speed signal-detector, etc. should fail or operate erroneously, the safety of passengers can be secured, and the elevator equipment can be prevented from being damaged.
