Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual radial gap motor systems require multiple controllers and resolvers for each motor, increasing complexity and cost when multiple motors are used collectively in tandem, as each motor needs individual control and positioning systems.
Innovation Solution
A modular motor system where multiple dual radial gap motors are connected in a linear configuration with a common controller and resolver, using a polygon-shaped rotor shaft for synchronization and a multi-lobe connection to share resources, allowing incremental power adjustment by adding or removing modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple dual radial gap motors are used collectively in tandem to increase power output, then the total power output is improved, but the system complexity and cost increase due to requiring multiple controllers and resolvers
Solution Approach 1:
The patent merges multiple motor controllers into a single shared controller that can control multiple motors simultaneously. The controller receives feedback from all motors through a common resolver and coordinates their operation, thereby reducing the total number of controllers needed while maintaining the ability to deliver increased power output through multiple motors working in tandem.
Solution Approach 2:
The controller is designed with universal functionality to control multiple motors rather than being dedicated to a single motor. The resolver provides collective rotational angle information for all motors, enabling the single controller to manage the entire motor cluster as an integrated system, thus reducing component quantity while preserving control capability.
2Power
If multiple dual radial gap motors are used collectively in tandem to increase power output, then the total power output is improved, but the system cost increases due to requiring multiple controllers and resolvers
Solution Approach 1:
The patent combines multiple expensive controller and resolver components into a single shared unit, directly reducing the bill of materials cost. By having one controller and one resolver serve multiple motors, the system eliminates redundant components, thereby reducing overall system cost while maintaining the capability to deliver increased power output through the motor cluster.
3Device complexity
If a modular motor system with a common controller and resolver is used, then system complexity and cost are reduced, but the challenge arises in synchronizing multiple motors to operate collectively
Solution Approach 1:
The resolver provides collective rotational angle feedback from all motors in the cluster to the single controller. This feedback mechanism enables the controller to monitor the position and orientation of each motor and adjust their operation to maintain synchronization, thereby solving the synchronization challenge while using fewer components.

This approach reduces system complexity and cost by enabling flexible power output adjustment with a single controller and resolver, while maintaining synchronized operation across all motors in the cluster.
Implementation Method 1
The common rotor power output shaft employs a polygon shape to operationally connect and synchronize the magnetic orientation of the rotors of each of the motor modules with one another
Implementation Method 2
A stator composed of a circular array of induction coils is encircled by the annular rings and centrally positioned so that there are equal gaps between the induction coils and the magnets of both rings
