Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotor and stator systems require significant hardware and magnetic pole count for motive force generation, and they often necessitate high DC requirements, which limits efficiency and increases energy consumption.
Innovation Solution
The system employs a linear or rotary motor with a stator having increasing magnetic density from one end to the other, utilizing a magnetic element that moves along this stator to generate motive force through an increasing attractive force, allowing for reduced hardware and energy requirements by using a minimal rotor configuration with only one magnetic pole and generating electrical energy as a byproduct.

Engineering Contradiction Analysis
1Force
If conventional rotor and stator systems are used with multiple magnetic poles, then motive force generation is achieved, but hardware requirements and magnetic pole count increase
Solution Approach 1:
The patent employs an asymmetric magnetic circuit design where the rotor contains only one magnetic pole instead of the conventional multiple poles. This asymmetric configuration, combined with a specially designed magnetic circuit in the stator, generates motive force through magnetic attraction while reducing the number of magnetic poles and associated hardware components.
Solution Approach 2:
The magnetic circuit is designed with varying magnetic properties at different locations. The stator contains magnetic elements with different permeabilities or configurations in different zones, allowing the system to generate sufficient motive force with a single rotor pole by concentrating magnetic flux in specific regions rather than requiring multiple distributed poles.
2Force
If conventional systems with multiple magnetic poles are used, then motive force is generated, but DC requirements and energy consumption increase
Solution Approach 1:
The single-pole rotor configuration reduces the number of magnetic pole pairs that need to be switched during operation, thereby reducing the DC power requirements and energy consumption compared to conventional multi-pole systems that require complex commutation or electronic switching.
Solution Approach 2:
The magnetic circuit design allows the system to efficiently utilize the magnetic field generated by a single pole, reducing the need for additional energy input to maintain motive force. The varying magnetic properties in the stator create a self-reinforcing magnetic flux pattern that reduces overall energy requirements.
3Device complexity
If a single magnetic pole rotor configuration is used, then hardware requirements are reduced, but motive force generation capability is limited
Solution Approach 1:
The stator is designed with magnetic elements having different local properties (varying permeability, saturation characteristics, or geometric configurations) to concentrate and direct magnetic flux effectively. This local optimization compensates for the single rotor pole limitation and generates sufficient motive force.
Solution Approach 2:
The magnetic circuit parameters (such as permeability, air gap dimensions, or magnetic material properties) are varied along the stator to optimize flux distribution. By changing these parameters spatially, the system achieves effective motive force generation with minimal rotor complexity.
