Solution Overview
Problem
Existing planar drive systems are limited by the controller's finite computing capacity, which restricts the number of stator modules and rotors that can be effectively controlled, preventing efficient operation beyond a predetermined number.
Innovation Solution
The system employs a dual-planar drive partial system with two controllers that cooperate to manage a larger number of stator modules and rotors, allowing for coordinated control through data exchange and actuating value calculations across adjacent stator surfaces.

Engineering Contradiction Analysis
1Quantity of substance
If a single controller is used to manage planar drive system, then the control structure remains simple, but the number of stator modules and rotors that can be effectively controlled is limited by finite computing capacity
Solution Approach 1:
The control system is divided into multiple controllers (first controller and second controller), each responsible for specific stator modules and rotors. This segmentation allows the system to manage a larger total number of components by distributing the computational load across multiple control units, thereby resolving the contradiction between controlling more components and maintaining simple control structure.
Solution Approach 2:
The system transitions from a single-controller architecture to a multi-controller architecture, adding a dimensional aspect to the control structure. This dimensional change enables scalable control where additional controllers can be added to manage increased numbers of stator modules and rotors without overwhelming a single controller's computing capacity.
2Adaptability or versatility
If the number of controlled stator modules and rotors increases beyond predetermined limits, then operational flexibility improves, but the controller's finite computing capacity is exceeded
Solution Approach 1:
By segmenting the control system into multiple controllers, each handling a subset of stator modules and rotors, the system achieves both operational flexibility and reliable performance. Each controller operates within its computational limits while the collective system provides enhanced adaptability through coordinated control of multiple components.
Solution Approach 2:
The controllers act as intermediaries between the control system and the actuators (stator modules and rotors). This intermediary architecture allows the system to scale to larger numbers of components while maintaining reliable performance by distributing the computational burden and preventing any single controller from being overwhelmed.
3Productivity
If multiple controllers are introduced to manage larger numbers of stator modules and rotors, then control capability increases, but system complexity increases
Solution Approach 1:
The control capability is enhanced by segmenting the system into multiple controllers, each managing specific portions of the stator modules and rotors. This segmentation increases overall productivity and control capability while keeping individual controller complexity manageable through clear division of responsibilities.
Solution Approach 2:
Each controller handles only the portion of control tasks assigned to it, performing partial action rather than attempting to control the entire system. This partial action approach enables the system to achieve high overall control capability while maintaining simpler individual controller architectures.

AI summary
A planar drive system includes first and second planar drive partial systems. A rotor is movable above a first stator surface in at least two directions, with the aid of first drive elements. The rotor has rotor drive elements for this purpose. The first planar drive partial system also includes a first controller with which the first drive elements can be actuated. The rotor can be moved above the second stator surface in at least two directions with the aid of second drive elements, if the rotor is arranged above the second stator surface. The second planar drive partial system further includes a second controller with which the second drive elements can be actuated. The first stator surface is adjacent to the second stator surface. In a transition area, the rotor is driven cooperatively by the first planar drive partial system and by the second planar drive partial system.
