Linear Motor Connecting Member for Sliding Door Cabling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear motor drive systems for sliding door systems face challenges in minimizing dimensions and efficient cabling due to space constraints, requiring components like control circuits and power supplies to be placed consecutively along the stator, leading to complex cabling issues, especially when the energy supply is located at the end of the stator remote from the terminal.
Innovation Solution
A linear drive system arrangement featuring a connecting member with integrated circuitry and a housing that includes terminals for external energy supply, allowing for centralized cabling through channels and protective cover members, along with a mounting device that simplifies assembly and reduces the risk of short circuits by using bush-shaped through-openings and a slide-in device for easy component alignment.

1Area of stationary object
If components are consecutively disposed in a row along the stator, then the linear drive system achieves minimum cross-sectional dimensions, but cabling complexity increases due to remote energy supply connections
Solution Approach 1:
The patent merges the energy supply connection, control circuit, and cabling management into a single integrated connecting member housing. This consolidation allows all connections to be accessed through one location rather than requiring separate access points along the stator, thereby reducing cabling complexity while maintaining the compact consecutive arrangement of components.
Solution Approach 2:
The connecting member housing acts as an intermediary structure that provides a centralized interface for external connections. It includes connection possibilities for energy supply and channels for guiding connecting lines, serving as a mediator between the external environment and the internal components, thus simplifying the cabling architecture.
2Ease of manufacture
If the connecting member housing includes through-openings for attachment screws, then ease of assembly and disassembly is improved, but the risk of screws entering the inner space and causing short circuits increases
Solution Approach 1:
The through-openings are segmented into separate sections: one section provides access for attachment screws from the exterior, while another section provides access to operating elements. This segmentation allows screws to be accessed and secured without providing a direct pathway into the inner space where electronic components are located, thereby maintaining reliability while preserving ease of assembly.
Solution Approach 2:
The patent extracts the screw access function from the inner space by providing dedicated through-openings that allow screws to be inserted and secured from the exterior without requiring access to the interior compartment. This separation takes out the potential hazard of screw intrusion while maintaining the ease of assembly benefit.

AI summary
A linear motor arrangement for panels, in particular sliding door leaves, movable along a travel path, as well as to a device for mounting such an arrangement includes a linear drive system having at least one stator member of a linear motor and a connecting member as components. The connecting member comprises a circuitry. The components are consecutively disposed in a row. Furthermore, the connecting member has a housing, which, at one end, has at least one connection possibility for an external energy supply. In addition, the housing, respectively the connecting member is adapted, to receive circuitry, which has additional terminals. In order to be able to run connecting lines in the connecting member, a channel is configured in the housing such that they are led out of the housing at the end of the connection possibility.
