Motor Mounting Bracket With Integrated Encoder Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor designs face issues with weak protection for the encoder during mounting, large overall volume, and high costs, particularly due to the encoder being mounted outside the rear end cover.
Innovation Solution
A mounting bracket is designed with a bracket body that includes a bearing mounting portion and a protective cover, creating an accommodation space for the encoder, which is fixedly connected to the protective cover, ensuring the encoder is securely mounted within the motor, reducing volume and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the encoder is mounted outside the rear end cover, then the encoder is easy to access for mounting, but the protection for the encoder is weak and the overall volume increases
Solution Approach 1:
The patent merges the encoder mounting function with the rear end cover structure by integrating an encoder mounting plate and protective cover into the existing motor housing. The encoder is mounted within the rear end cover assembly rather than externally, combining protection and mounting functions into a single integrated structure.
Solution Approach 2:
The encoder is nested within the rear end cover structure, with the encoder mounting plate positioned inside the cover and the protective cover enclosing it. This nested arrangement provides protection while maintaining compact integration within the motor assembly.
2Device complexity
If the encoder is mounted outside the rear end cover, then the mounting structure is simple, but the overall volume of the motor is large
Solution Approach 1:
The encoder mounting structure is merged with the rear end cover, eliminating the need for separate external mounting brackets or housings. The encoder mounting plate and protective cover are integrated into the rear end cover assembly, reducing overall motor volume while maintaining structural simplicity.
Solution Approach 2:
The encoder is positioned in a different spatial dimension within the rear end cover assembly, utilizing the internal space of the cover rather than extending externally. This dimensional reorganization reduces the motor's external footprint while accommodating the encoder.
3Ease of manufacture
If the encoder is mounted outside the rear end cover, then the mounting process is straightforward, but the motor costs are high
Solution Approach 1:
The encoder mounting plate and protective cover are integrated into the rear end cover assembly, reducing the total number of separate components. This integration simplifies the manufacturing process and reduces assembly steps, thereby lowering production costs.
Solution Approach 2:
The rear end cover assembly serves multiple functions: it provides structural support, houses the encoder mounting plate, and includes the protective cover. This multi-functionality reduces the need for additional specialized components, lowering overall manufacturing costs.

AI summary
A mounting bracket and motor including same have mounting bracket arranged on side of the motor's casing away from front end cover, and includes bracket body. A bearing mounting portion for mounting motor's bearing is on bracket body's side close to casing; and protective cover and at least one of protective cover mounting portion and encoder bracket mounting portion on bracket body's side away from casing. Protective cover mounting portion is configured to fixedly connect bracket body and protective cover. Accommodation space for accommodating encoder is defined between bracket body and protective cover; or encoder bracket mounting portion includes first encoder bracket mounting portion, and first encoder bracket mounting portion is fixedly connected to protective cover by encoder bracket. Accommodation space for accommodating encoder is defined between encoder bracket and protective cover, to resolve weak protection problems for encoder during mounting, large motor's overall volume motor, and high motor costs.
