Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current FaulHaber winding type motors face limitations in producing more torsion and power with the same motor volume due to the need for increased magnet pairs, which results in greater bending angles of enameled wire, leading to issues like current leakage and reduced insulation and pressure resistance.
Innovation Solution
A motor with a coil structure featuring three winding groups, each with multiple winding portions and intervals, electrically connected by wires, and additional magnetic materials disposed adjacent to the coil structure, allowing for increased magnetic materials without altering the bending angle, thereby enhancing magnetic field density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If more magnet pairs are used to increase torsion and power output, then the motor can produce more force, but the bending angle of the enameled wire increases leading to current leakage and reduced insulation
Solution Approach 1:
The coil structure is divided into multiple independent winding groups (first, second, and third winding groups) with each group containing multiple winding portions. This segmentation allows the magnetic field to be generated through distributed windings rather than requiring excessive bending of individual wire segments, thereby maintaining insulation integrity while achieving the desired torsion output through collective electromagnetic action of all winding groups.
Solution Approach 2:
The patent transitions from a traditional single-layer or two-layer winding arrangement to a three-dimensional multi-group winding configuration. The winding groups are arranged in different spatial dimensions and orientations, allowing the magnetic field to be generated through spatial distribution rather than increasing the bending angle of wire in a single plane. This dimensional expansion enables more magnet pairs to be effectively utilized without compromising wire insulation.
2Power
If more magnet pairs are used to increase power output, then the motor can produce more power, but the bending angle of the enameled wire increases leading to reduced pressure resistance
Solution Approach 1:
The coil structure is divided into multiple independent winding groups (first, second, and third winding groups) with each group containing multiple winding portions. This segmentation allows the magnetic field to be generated through distributed windings rather than requiring excessive bending of individual wire segments, thereby maintaining insulation integrity while achieving the desired torsion output through collective electromagnetic action of all winding groups.
Solution Approach 2:
The patent employs a composite winding structure combining multiple winding groups with different orientations and configurations. This composite approach creates a more robust overall structure that can withstand operational pressures better than a single winding configuration would, while still accommodating multiple magnet pairs for enhanced power output.
3Force
If more triangle pairs are formed to increase magnetic materials, then the motor can produce more torsion, but the enameled wire needs to be bent more times resulting in smaller bending angles
Solution Approach 1:
The coil structure is divided into multiple independent winding groups (first, second, and third winding groups) with each group containing multiple winding portions. This segmentation allows the magnetic field to be generated through distributed windings rather than requiring excessive bending of individual wire segments, thereby maintaining insulation integrity while achieving the desired torsion output through collective electromagnetic action of all winding groups.
Solution Approach 2:
Each winding group is designed with the same winding procedure and structure, making them universal and interchangeable in function. This multi-functionality allows the system to achieve complex magnetic field patterns through repeated, standardized winding units, reducing overall winding complexity while maintaining high torsion output capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the motor to output more torsion and power with the same motor volume, improving efficiency by maintaining the same bending angle while increasing the number of magnetic materials, thus enhancing the magnetic field density.
Implementation Method 1
Motors are commonly used devices for converting electricity into mechanical energy, thus applied to various kinds of machines... They principally function by the electromagnetic effect
Implementation Method 2
The triangle portion provides the positive exciting, and the inverted triangle portion provides the negative exciting, thereby rotating the rotor by the switch driving of the circuit
Implementation Method 3
The enameled wire is bent to conduct the winding, and from appearance the main characteristic of the coil is winding towards the diagonal direction

AI summary
A motor comprises a coil structure and a plurality of magnetic materials. The coil structure includes three winding groups, each of which has a plurality of winding portions. The winding portions have an interval therebetween, and are electrically connected by a wire. The magnetic materials are disposed adjacent to the coil structure and corresponding to the winding groups. Accordingly, the motor has more magnetic materials within the same bending angle of the enameled wire, so that the motor can output larger torsion and power to enhance the motor efficiency.
