Adjustable Motor Drive Frame with Movable Connection Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Facilities face challenges in managing and storing spare motors due to space requirements and the need for accurate inventory tracking, as well as the cost of maintaining multiple spare motors that may never be used, especially for critical operations where downtime needs to be minimized.
Innovation Solution
An adjustable motor drive system with a wide power output range, an adjustable frame, and mount, allowing for independent adjustment of shaft height and footprint, which can function as a versatile spare for various motors and foundations, reducing the need for multiple spare motors by allowing temporary installation and easy reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facilities store multiple spare motors for critical operations, then reliability is improved, but storage space requirements and inventory management complexity increase
Solution Approach 1:
The motor frame is designed with multiple adjustable connection holes that allow a single frame to accommodate motors of different shaft heights and configurations. The frame can be reconfigured by moving connection holes to different positions, enabling one frame to serve as a universal spare for multiple motor types rather than requiring separate frames for each motor size.
Solution Approach 2:
The connection holes in the motor frame are made movable rather than fixed, allowing the frame structure to dynamically adapt to different motor configurations. This adjustability enables the same frame to be reconfigured for different shaft heights and motor sizes, reducing the need to store multiple static frame variants.
2Adaptability or versatility
If facilities maintain multiple spare motors for different configurations, then adaptability is improved, but cost and inventory management complexity increase
Solution Approach 1:
A single motor frame with adjustable connection holes can accommodate multiple motor configurations and shaft heights. This universal design allows facilities to maintain one adaptable frame instead of multiple configuration-specific frames, reducing the quantity of spare parts needed while maintaining versatility.
Solution Approach 2:
The motor frame is segmented into adjustable components with movable connection holes that can be repositioned independently. This segmentation allows the frame to be customized for different motor configurations without requiring completely different frame designs, enabling one frame to replace multiple specialized frames.
3Manufacturing precision
If motor shaft height is fixed in the frame, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The connection holes are designed to be movable within the frame while maintaining precise positioning when installed. This allows the frame to adapt to different shaft heights through repositioning connection holes, while each specific configuration maintains manufacturing precision when the connection holes are fixed in their selected positions.

AI summary
A system includes a motor, a frame, and connecting bolts. The motor includes a shaft. The frame is configured to house the motor. The frame includes connection holes and a base. Two or more of the connection holes are selected corresponding to a selected height of the shaft. The base is configured to mount the motor onto a foundation. Each of the connecting bolts is configured to pass through a respective connection hole and bolt to the motor to secure the motor to the frame.
