Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of electrical components in motors leads to enlargement, particularly in the radial direction, necessitating an optimized layout to prevent motor expansion.
Innovation Solution
A motor design featuring a cylindrical housing, an end bracket with a connector support, power supply terminals, a noise prevention element, and a rotation detector, where the noise prevention element is positioned between the power supply terminals and aligned axially, and the detector body is also aligned axially, allowing for a compact layout that avoids radial enlargement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of electrical components is increased, then the functionality is improved, but the motor size is enlarged
Solution Approach 1:
The patent transitions from radial arrangement to axial arrangement of electrical components. Specifically, the noise prevention element and rotation detector are positioned along the axial direction within the end bracket, rather than radially around the stator. This dimensional change allows multiple components to be compactly arranged without increasing the motor's radial dimensions, thus maintaining compact size while accommodating increased functionality.
Solution Approach 2:
The patent nests multiple electrical components within the end bracket structure. The noise prevention element and rotation detector are integrated into the end bracket's internal space, utilizing the hollow portion and axial arrangement to house multiple components in a nested configuration. This nesting approach maximizes space utilization without requiring additional radial space.
2Device complexity
If electrical components are arranged radially, then the layout is simple, but the radial dimension is enlarged
Solution Approach 1:
The patent changes the arrangement dimension from radial to axial. The noise prevention element and rotation detector are positioned along the axial direction within the end bracket, specifically utilizing the hollow portion for axial arrangement. This eliminates the need for radial space while maintaining layout simplicity through structured positioning along the motor axis.
3Device complexity
If the noise prevention element and rotation detector are arranged separately, then the electrical connections are simplified, but the space occupation is increased
Solution Approach 1:
The patent merges the noise prevention element and rotation detector into a unified axial arrangement within the end bracket's hollow portion. Both components are positioned along the axial direction in close proximity, sharing the same spatial zone. This combined arrangement reduces the total space occupied compared to separate radial positioning, while the power supply terminals provide integrated electrical connections to both components.

AI summary
A motor including electrical components laid out to avoid enlargement of the motor. The motor includes a rotor, a cylindrical housing including a closed end and an open end and accommodating the rotor, and an end bracket fixed to the housing to close the open end and including a connector support. Two power supply terminals extend to the connector support. A noise prevention element includes a connection terminal connected to the power supply terminals. A rotation detector detects rotation of the rotor and includes a detector body. The noise prevention element is arranged between the two power supply terminals. The detector body and the noise prevention element are arranged at a portion of the end bracket closer to the connector support and aligned in an axial direction of the motor.
