Motor Mount Recesses for Cooling Airflow at Housing Ends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cooling performance at the ends of motor housings, where they are fastened to motor mounts, is insufficient due to the obstruction of air flow by the mounts, which cover the air inlets and outlets of the cooling fins, leading to reduced efficiency in heat dissipation.
Innovation Solution
A ring-shaped motor mount with recesses that guide cooling air from the outer circumference to the inner circumference, forming air-conducting channels that enhance the flow to the ring aperture cross-section, ensuring improved air flow distribution and utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a full-faced motor mount is used to fasten the motor housing to the motor mount, then the structural support and stability are improved, but the cooling air flow to the ends of the motor housing is blocked, worsening the cooling performance
Solution Approach 1:
The motor mount is designed as a ring-shaped structure with multiple recesses instead of a solid full-faced mount. This segmentation allows cooling air to pass through the mount structure itself, while still providing structural support for fastening the motor housing.
Solution Approach 2:
The ring-shaped motor mount has different properties in different regions: the outer circumference provides structural support for fastening, while the inner circumference with recesses allows air flow penetration. This local differentiation resolves the contradiction between support and cooling.
2Productivity
If a ring-shaped motor mount is used to allow air flow through the center, then the cooling air access to the motor housing ends is improved, but the air flow velocity and pressure in the ring aperture region is insufficient, worsening the cooling efficiency
Solution Approach 1:
The recesses in the motor mount pre-direct and channel the cooling air flow from the outer circumference toward the inner circumference before it reaches the motor housing ends. This preliminary action accelerates and focuses the air flow, ensuring sufficient velocity and pressure for effective cooling.
Solution Approach 2:
The recesses act as intermediary air-conducting channels that transfer cooling air from the fan region through the motor mount structure to the motor housing ends. These recesses mediate between the fan-generated air flow and the cooling fins, ensuring efficient air delivery.
3Area of moving object
If cooling fins with outwardly open channels are used on the motor housing, then the heat dissipation surface area is increased, but the air inlets and outlets are covered by the motor mount, worsening the heat dissipation efficiency
Solution Approach 1:
The ring-shaped motor mount with recesses is nested around the motor housing ends, allowing the cooling air flow to pass through the mount structure and reach the cooling fins. The recesses are positioned to align with the air inlets and outlets of the cooling channels, ensuring that the mounting structure does not block but rather facilitates air flow to the heat dissipation surfaces.
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
The recesses in the motor mount facilitate enhanced cooling performance by directing air flow effectively to the motor housing ends, improving heat dissipation and overall cooling efficiency.
Implementation Method 1
The rotation of the fan or of the end impeller causes an air flow to be generated, some of which is conducted along the cooling fins of the motor housing through the flow channels formed by the cooling fins
Implementation Method 2
The heat generated by the electric motor can thus be dissipated via the motor housing using the air flow generated by the fan or the end impeller

AI summary
A device for conducting cooling air on a motor mount for a fan motor, in particular an electric fan motor or a fan-cooled motor. The device has multiple recesses extending on an end of the ring-shaped motor mount from the outer circumference of the ring-shaped motor mount to the inner circumference of the ring-shaped motor mount, to conduct some of an air flow generated by the fan at the outer circumference of the ring-shaped motor mount to the ring aperture cross-section.
