Layered Motor Circumferential Stacking for High Output Compact Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motors are large in size due to the need for a larger rotor diameter to achieve high output, making it difficult to implement small yet high-output motors.
Innovation Solution
A layered motor design where stators and rotors are disposed in multiple alternating layers along the circumferential direction, allowing for electromagnetic interaction to generate rotational force and maximize output without increasing motor size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the rotor diameter is increased to increase output, then the output is improved, but the motor size increases
Solution Approach 1:
The motor is divided into multiple independent stator-rotor layer sets arranged in the circumferential direction. Each layer functions as an independent electromagnetic interaction unit, with stators and rotors alternately stacked to form discrete segments that collectively produce the total output.
Solution Approach 2:
The invention transitions from a single-plane radial configuration to a multi-layer circumferential stacking arrangement. By adding the circumferential stacking dimension, the motor achieves increased output through multiple layers rather than increasing the rotor diameter in the radial direction, thus resolving the contradiction between output and size.
2Power
If multiple stators and rotors are arranged in alternating layers, then the output is increased without increasing motor size, but the device complexity increases
Solution Approach 1:
Multiple stator-rotor layers are merged into a single integrated motor structure sharing common housings, shafts, and control systems. The alternating layer configuration allows electromagnetic interactions from multiple sets to be combined additively, achieving high output while maintaining a compact unified structure rather than multiple separate motors.

Function Achieved in This Case
The layered motor achieves a higher output comparable to combining multiple motors while maintaining a smaller size, enabling efficient operation in various mechanical devices.
Implementation Method 1
electromagnetic interaction occurs between the stator and rotor, causing the rotor to be pushed in one direction and, as a result, rotating the motor shaft

AI summary
Proposed is a layered motor, in which stators (300) are disposed along a circumferential direction inside a housing (100), and rotors (200) are disposed along a circumferential direction adjacent to the stators (300), wherein the rotors (200) are connected to a motor shaft (120) and rotate due to the electromagnetic interaction between the stators (300) and the rotors (200), thereby rotating the motor shaft (120), and the stators (300) and the rotors (200) are disposed in a plurality of layers alternating with each other in the circumferential direction.
