摘要： PURPOSE:To simplify a structure as well as to make it light in weight by forming a cut-out section on each end face of a iron core in the longer direction, forming a key groove on each presser plate located at both the ends of the core, putting keys in each cut-out section and each key groove so as to be integrated, and thereby fastening both the presser plates with a stud so as to be fixed. CONSTITUTION:Each iron core 20 comprising a linear motor is laminated in such a way that each inner circumferential surface coaxial with a secondary conductor is formed at the slot side of each steel plate in a comb teeth shape so as to be fixed with a stud 21, and each cut-out section 20c is formed on both the end faces in the longer direction. Each presser plate 22 is formed with a key groove 22a at the position faced to the position of each cut-out section 20c of the iron core 20, cylindrical coils 15 are disposed in the slot section of each iron core 20, and each key 23 which is fitted in the cut-out section 20c, is put in the key grooves 22a thereafter. On the other hand, the respective presser plates 22 are connected to each other with a stud 24 so as to be fixed, the linear motor 19 is integrally made up while each iron core 20 is being held therein so as to be fixed. In this case, each iron core 20 is positioned at a specified place in the circumferential direction with no dislocation with respect to the presser plates 22 through the action of each key 23.

摘要： PURPOSE:To make the motor light in weight by driving a wedge between an end plate, which catches the laminated core of a linear motor where coils are fitted in plural slots, and a frame, which fixes the linear motor to the above frame. CONSTITUTION:A linear motor 30 is equipped with an core body 8, and the end plates at both sides catch a laminated core 8a. The core 8a is provided with plural slots, and it forms a coil 14. The coil 14 and the laminated core are covered from sides with covers 11 whose cross sections are U-shaped. The core body 8 is pressed from both sides with core pressers 31 and 32. Covers can be attached to the core pressers 31 and 32, and also those are fixed to the frame 34 attached to a car body outside the figure. A wedge 35 is driven on at least one hand between the end plates on both sides of the laminated core 8a and the core pressers 31 and 32. Hereby, the frame and the core body are united, and the rigidity improves as it is light.

摘要： PURPOSE:To enhance the efficiency so as to prevent power consumption from increasing, by making gaps between a linear motor side and a reaction plate side as uniform as possible. CONSTITUTION:First and second coils are bent in conformity with a substantially diamond cross-sectional shape of a reaction plate member 52, and accordingly, all gaps between first and second plate surfaces 52b, 52d and a core 55 can be made to be substantially uniform. Further, since the diamond cross-sectional shape of the reaction plate member 52 enhances the rigidity, thereby it is possible to decrease deflexion upon a start of a linear motor.

摘要： PROBLEM TO BE SOLVED: To surely detect wearing of a guide roller used to serve as preventive maintenance. SOLUTION: In this elevator driving linear motor device, in the beginning of use started, a guide roller 10a, while coming into contact with a peripheral surface of a column 6, is rolled, a space distance between the column and a primary side circular coil is fixedly held in circumference each part. Use is advanced or a deviation is generated by any cause, when wearing is advanced of all the guide rollers or specific guide roller, an auxiliary roller 20a of hard material is brought into contact with the column 6. When this auxiliary roller is started to come into contact with the column, a sound different from a running sound till that time is generated, by a change of the running sound, an elevator utilizer and a maintenance person can be aware of advancing in wearing of the guide roller.

摘要： PURPOSE:To prevent flexure by fixing a plurality of reinforcing ribs between core holders in the shape of a ladder, holding such a space as it does not the ribs into contact with the rear of a core and, at the same time, fixing the rear of the core and the sides of the reinforcing ribs to each other with core bearing materials. CONSTITUTION:Two core holders 10 are welded and fixed to each other with mounting holders 18 and reinforcing ribs 20 extending between them to form a frame 22 together as a unit. At that time, a space is so held that the reinforcing ribs 20 don't come into contact with the rear 8e of a core body 8. After that, the ends 26a of core bearing materials 26 having L shaped sections on the rear 8e of the core body 8 are so closely fixed that they overlap the wall surfaces 20a of the reinforcing ribs 20. In addition, after the lower ends of the core bearing materials 26 are welded with the rear 8e of the core body 8 to fix, the core bearing materials 26 and the reinforcing ribs 20 are welded to fix.

摘要： PURPOSE:To prevent intrusion of foreign matter from outside while ensuring ventilation by arranging many recesses and protrusions through press on the under face cover plate section and making vents at the rising side face section of the recess or the protrusion. CONSTITUTION:Many vents 23 are punched through the upper face cover 20a and the outside face cover 20c of a coil cover 20 for covering the coil end sections 9a projecting to the opposite sides of the core for a linear motor. Many recesses 24 are arranged through press in the under face cover plate section 20b, where rising side face sections in front and rear of each recess 24 are opened as a vent 25. Since the vents 23, 25 do not face with the rail face, foreign matter such as rubble does not enter from the rail face into the coil cover 20.
