Secondary device of grid-like linear motor for linear motor rail traffic

摘要

The present invention relates to a secondary device for a linear linear motor for linear motor rail traffic, comprising a magnetically conductive core (5), a conductor (6), and a mounting frame (7). , Including a pair of conductive rods (61) arranged in a grid and a conductive end rod (62) connecting the ends of the adjacent conductive rods (61), and the conductive iron core (5) is connected to the conductive rod. Corresponding mounting grooves (51) are provided, the conductive rods (61) are fitted into the mounting grooves (51), and the two ends of the conductive rods (61) both extend from the mounting grooves (51). The present invention relates to a secondary device for a grid-shaped linear motor for linear motor rail traffic in which an end bar (62) is provided on a side portion of a magnetic iron core (5) and a magnetic iron core (5) is provided on a mounting frame (7). . The magnetic iron core (5) is punched and laminated from the silicon steel plate, and the silicon steel plate is laminated along the longitudinal direction of the conductive rod (61). The conductive rod (61) and the conductive end rod (62) are made of a material having good conductive performance. The secondary of the linear motor adopts a whole new structure and uses materials with good conductive performance and magnetic conductivity performance, effectively reducing the eddy current loss in the secondary induction plate, and the traction force of the motor And an excellent energy saving effect can be obtained.
