This guide addresses a common question among robotics designers and mechanical engineers: “Where is theservolibrary in SolidWorks?” The short answer is that SolidWorks does not include a dedicated, pre-installedservolibrary. However, you can easily access, import, and manageservomodels through several built-in tools and external resources. Below you will find the exact locations, step‑by‑step procedures, and best practices to build your own reusable servo library.
The first place to look is theDesign Library, but you will not find any servo models there by default.
Location:In the Task Pane (right side of the SolidWorks window), click theDesign Librarytab.
What you see:Folders such asAnnotations, Features, Parts, Assemblies, andRouting. No “Servo” folder exists in a standard installation.
Common case:A user opens the Design Library expecting a ready‑made servo category. Finding none, they assume the software is missing a feature. In reality, servos are not part of SolidWorks’ standard content because they are electrical components, not generic mechanical parts like bolts or bearings.
Some users confuse the Toolbox with a servo library.
Toolbox location: Tools > Add‑Ins> checkSolidWorks Toolbox Library.
Toolbox content:ANSI/ISO standard fasteners, bearings, shafts, and structural shapes –in the servants.
Why not:Toolbox is designed for hardware that follows mechanical standards. Servo motors have varied shapes, mounting patterns, and electrical interfaces, so they are not included.
Since SolidWorks lacks a native servo library, you must create one. Follow these steps:
Many free and paid platforms offer verified CAD models of popular servo motors (e.g., 9g, MG995, MG996R, DS3225).
Recommended sources (no brand names):
Official 3D content platforms of CAD software vendors
Manufacturer websites under “Support” or “Downloads”
Community‑driven libraries with user ratings and file validation
File formats to choose:STEP (.step, .stp) for highest compatibility, or native SolidWorks parts (.sldprt) if available.
> Real‑world example:A robotics team needed a standard 20 kg・cm servo for a robotic arm. Instead of modeling from scratch, they downloaded a STEP file from a verified manufacturer page. The model included exact mounting hole positions and output shaft dimensions, saving three hours of design work and preventing assembly interference.
After downloading, import the file into SolidWorks and store it in a custom library folder.
1. Open SolidWorks and create a new part or assembly.
2. UseInsert > Part(for a part) orInsert > Component > Existing Part/Assembly(for an assembly).
3. Navigate to the downloaded file and open it.
4. (Optional) Add custom properties – e.g.,Part Number, Description = "Standard Servo Motor", Vendor, Torque_Nm.
5. Save the file in a dedicated folder that you control.
Recommended folder path: C:\Users\Public\Documents\My_Servo_Library\(or any network location shared by your team).
6. Add that folder to the Design Library:
Right‑click the Design Library task pane >Add to Library> select your servo folder.
Now the folder appears under the Design Library for one‑click access.
A well‑structured library increases your design efficiency. Use subfolders like:
Servo_Full_Models(complete external geometry)
Servo_Simplified(bounding boxes or simplified solids for large assemblies)
Servo_Mounting_Brackets
Datasheets(PDFs with torque curves, dimensions, and wiring)
If you do not want to download files in advance, use the built‑in online content search.
Location: Tools > Design Library > Online Content(or the “Search online” field at the top of the Design Library task pane).
How it works:SolidWorks connects to the vendor’s 3D content platform. Type “servo” and filter by file type (SolidWorks or STEP).
Limitation:Requires an active internet connection and may return many irrelevant results. Always verify the model’s claimed dimensions against the manufacturer datasheet.
Mistake 1:Searching for a “servo library” inside SolidWorks for hours.
Solution:Understand that no such default library exists – move immediately to downloading and importing.
Mistake 2:Using low‑quality models from unverified sources.
Solution:Prefer STEP files from manufacturer websites or platforms that show a “verified” badge and user reviews. Test the model by mating it in a dummy assembly before relying on it.
Mistake 3:Saving servo models in random folders and losing them later.
Solution:Create a permanent, named library folder and add it to the Design Library as shown above.
To work efficiently with servos in SolidWorks, take these three actions today:
1. Create your own servo library folderon your local drive or team server. Populate it with models of the servos you use most often. Start with two or three common types (e.g., a mini servo and a standard size).
2. Always download STEP fileswhenever possible – they preserve accurate geometry and are not tied to a specific CAD version. Convert them to SolidWorks parts and add custom properties for easy searching.
3. Document your library structurein a simple README file inside the folder. Include notes on which models have been verified, their torque ratings, and typical applications.
Final core takeaway:SolidWorks does not come with a built‑in servo library, but you can build a custom, reusable library in under 10 minutes using free online models and the Design Library. This approach gives you full control over accuracy, organization, and team sharing – far more useful than any pre‑packed generic library. Start by downloading one servo model today, save it to a dedicated folder, and add that folder to your Design Library. You will never waste time searching for a servo model again.
