Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing linear motor systems for sliding doors face complexities in wiring, detection difficulties, and limited sliding range due to the arrangement of stators and power supply, leading to increased complexity and reduced adaptability.
Innovation Solution
A linear motor system with a control assembly positioned between two stator assemblies, allowing direct electric connection without crossing wires, and an adaptor and power supply connected to the outer sides of the stator assemblies, simplifying wiring and detection, and enabling increased sliding range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the power supply and connecting member are arranged at two sides of the two stators to enable effective connection with rotor members at any time, then the driving force is sufficient, but the wiring becomes complex as connecting wires must cross over stators
Solution Approach 1:
The linear motor system is divided into multiple independent stator assemblies (first stator assembly, second stator assembly, third stator assembly) that can be independently connected to the control assembly. This segmentation eliminates the need for wires to cross over stators, as each stator assembly has its own direct connection path to the control assembly, thereby reducing wiring complexity while maintaining sufficient driving force through distributed motor units.
2Force
If the stator is located in the middle of the door body to provide enough driving force by aligning coil groups with rotor members, then the driving force is sufficient, but the sliding range is limited and detection becomes difficult when the door body slides to two sides
Solution Approach 1:
The motor system uses multiple stator assemblies distributed along the sliding path rather than a single central stator. This allows the door body to slide through a larger range while maintaining effective magnetic coupling between rotor members and stator assemblies at different positions, thereby extending the usable sliding range and improving detection capability across the full travel distance.
Solution Approach 2:
The system transitions from a single-point driving force generation (central stator) to a distributed linear arrangement of multiple stator assemblies along the sliding direction. This dimensional expansion allows the door to be driven effectively across a longer range, with each stator assembly contributing to the overall driving force at different positions along the track.
3Device complexity
If the control assembly is arranged between two stator assemblies, then the wiring is simplified with direct electric connection, but the position of control assembly must be precisely determined
Solution Approach 1:
The control assembly is designed with multiple independent connecting ports that can connect to different stator assemblies. This segmentation provides flexibility in positioning the control assembly along the linear motor system, allowing installation at various locations while maintaining simplified wiring through direct connections to each stator assembly via the connecting ports.

AI summary
The present invention relates to a linear motor system for a sliding door, including a mover assembly connected with a door body of the sliding door, a control assembly and at least two stator assemblies, wherein the control assembly is configured to control the movement of the mover assembly and is arranged between two stator assemblies in the at least two stator assemblies. Due to the structure, a linear motor is more convenient to detect, and a simpler wiring way is also provided.
