Hi, I’ve reviewed your requirements for the 2207 12S14P outrunner BLDC motor, and I can handle the mechanical CAD and engineering documentation in SolidWorks, including the full assembly, exploded view, BOM, detailed 2D drawings, STEP/IGES, DXF and PDF deliverables. One important point I noticed is that the 0.15–0.20 mm air gap makes rotor concentricity, bearing alignment and tolerance stack-up especially critical. I would therefore build the assembly around a controlled master layout so the stator, rotor bell, magnets, shaft and bearing interfaces are dimensionally coordinated rather than modeled independently. I also noticed a few specifications that should be clarified before finalizing the design: 1)The shaft is specified as Ø4 or Ø5 mm, while the example 684ZZ bearing has a Ø4 mm bore. 2)The stator tooth/slot geometry and stator ID are not fully defined. 3)The magnet length is given, but magnet thickness, width/arc coverage and exact seating geometry are not specified. 4)The rotor bell wall thickness and some balancing-pocket details still need to be established. 5)The epoxy coating thickness may affect the effective air-gap and should be confirmed as part of the dimensional stack-up. If you already have a reference CAD model, existing drawing, physical sample dimensions, or a similar 2207 motor that this design is based on, I can use it as the reference and turn it into a clean, fully dimensioned and manufacturing-oriented CAD package. My focus would be on making the final drawings practical for manufacturing, with appropriate fits, tolerances, datums and GD&T rather than simply producing a visually complete 3D model. I can deliver the complete mechanical package in SolidWorks with STEP/IGES, DXF and PDF outputs. I’d be happy to start by reviewing any existing reference model or drawings and confirming the few missing dimensions before building the final assembly. Best regards,

Your project requires a complete engineering documentation package rather than only CAD drafting, so the focus is on developing manufacturable drawings, precise tolerances, assembly documentation, and production ready deliverables for the 2207 12S14P outrunner BLDC motor. I can prepare the fully dimensioned 2D drawings, 3D CAD models in STEP and IGES, exploded assembly with BOM, stator and rotor component drawings, shaft and bearing fit specifications, and GD&T where required to support manufacturing and assembly. Are the stator lamination profile and electromagnetic geometry already finalized, or do you expect the mechanical design to optimize the tooth and slot geometry as part of this project?

The core of this job is the stator dimensions, $22 \text{ mm} \pm 0.05 \text{ mm}$ outer diameter and $7 \text{ mm} \pm 0.05 \text{ mm}$ stack height, so I will model these in AutoCAD, setting the lineweights and layers to clearly define the critical tolerances. The silicon steel lamination thickness will be specified as 0.15 mm, this is a standard that offers good performance. I am not going to use fancy 3D rendering for the basic component drawings; that just adds cost and time for no benefit to the mechanical drawing itself. I will ensure the slot geometry is detailed to match the 12 slots specified, also showing the exact placement of the 14 rotor poles relative to the stator. 8 reviews on here, everything delivered on time and on the agreed price so far, plus Preferred Freelancer status. What is the required surface finish for the rotor magnet housing? Provide the existing CAD files if available.

Hello, I reviewed your specifications, and the main challenge appears to be producing a fully coordinated manufacturing package where every component, tolerance, fit, and assembly relationship is defined accurately enough for fabrication rather than serving only as a reference design. The stator, rotor, shaft, bearings, and mounting features must be developed as an integrated assembly with proper GD&T, interference fits, air gap control, and production ready documentation that aligns the 2D drawings with the 3D CAD models. I have worked on similar precision mechanical design and manufacturing documentation projects and can share relevant examples once we connect in chat. Best Regards, Atik
