Why are brushless motors installed?
Brushless motors are installed when the existing motors are too weak (current case) as they offer numerous advantages:
- Higher power and efficiency: brushless motors deliver more torque and power for the same size, making them ideal for replacing weaker motors.
- Longevity: As they work without brushes, they have less wear and require less maintenance.
- Better cooling: Brushless motors generate less heat loss, resulting in more stable performance.
- Precise control: They allow more precise control of speed and torque, which is necessary for demanding applications.
Therefore, they are a more optimal solution to improve the performance and efficiency of the system.
**Conceptual preparatory work for the implementation of the steering geometry:**
- Researched possible models
- STL files integrated into OnShape
- The following adjustments must be made:
- STL files integrated into OnShape (try to find more models on thingiverse)
- Models cannot currently be customized as they are STL files
- The models must therefore be remodeled
Conceptual integration of brushless motors into the existing onshape model
The integration of brushless motors into an existing onshape model requires the following steps at the conceptual level:
_Space requirements and geometry_
- Checking the installation space: Ensure that the brushless motor and any new components (such as controllers or heat sinks) fit into the existing installation space.
- Adaptation of the brackets: Updating or redesigning the mounting points and fasteners to securely integrate the brushless motor.
- Consideration of cable routing: Define routes for power and control cables in the model.
_Our recommended model:_

https://www.thingiverse.com/thing:6777944 (V2)
Ease of installation:
- Selected model: fixing points and dimensions fit into existing constructions without major adjustments.
Testimonials:
- Selected model: Positive feedback from the community or similar projects.
An improved version (V2) was developed by the original creator, which convinces through targeted optimizations in performance, efficiency and integration.
_The following adjustments must be made:_
- Analysis of the requirements
- Check dimensions: Checking the dimensions of the brushless motors and their components (motor,AGX, DC-DC-Converter, cabling) compared to the available space.
- Modeling the motors
- CAD import: If available, import the CAD data of the brushless motor and controller directly into Onshape.
- Detailed modeling: If CAD data is missing, create a true-to-scale geometry of the motors and controller in Onshape.
- Customization of the driving platform
- Mounting points: Create or customize the mounting surfaces for the motors.
- Ensure that screw holes, brackets or other fasteners are present and fit.
- Cable management
- Plan cable routes: add models for cable ducts, clamps or guides to route power and signal cables in an organized and protected manner.
- Adjusting the overall design
- Weight distribution: Ensure that the new motors do not affect the balance of the platform. Reposition components if necessary.
- Assembly test
- Assembly as an assembly: Integrate the motors into the onshape model of the driving platform as an assembly.
- Collision test: Check that all components fit together and that no collisions occur during operation.
- Version control and documentation
- Version creation: Create a separate version of the model for the integration of the brushless motors in order to make subsequent adjustments traceable.
- Documentation: Generate detailed drawings for production and assembly of the new components from Onshape.
- Validation and feedback
- Test assembly: Once modeling is complete, implement and test a prototype model based on the Onshape design.
- Iterative adaptation: Incorporate findings from the prototype test into the Onshape model.
