SUMMARY

To manufacture a stator and rotor for a motor from a CAD drawing, utilize local machine shops that offer plasma, waterjet, or laser cutting services. For small runs, profile cutting is more cost-effective than punching, which incurs high tooling costs. Provide a DXF file to the machine shop and be prepared to source electrical steel yourself, as it may not be in stock. Ensure to specify the required tolerances, materials, and finishes when requesting quotes.

PREREQUISITES
  • Understanding of CAD software for creating DXF files
  • Knowledge of materials, specifically electrical steel
  • Familiarity with machining processes such as laser cutting and waterjet cutting
  • Basic project management skills for sourcing and quoting
NEXT STEPS
  • Research local machine shops that offer laser cutting services
  • Learn about sourcing electrical steel for small manufacturing runs
  • Investigate the specifications for tolerances in machined parts
  • Explore CAD software options for creating and exporting DXF files
USEFUL FOR

Hobbyists, engineers, and makers interested in small-scale manufacturing of motor components, particularly those looking to convert CAD designs into physical parts.

Hi. I am trying to figure out how to get a stator and rotor manufactured for a motor I am building as a learning project. Anyone have any clue how I can get a stator manufactured from a cad drawing with electrical steel ?

Everything I see on the net is for large orders sigh. I have never done this before so I figured id ask for help. Am I going to have to make the stator myself or is it easy to find someone to machine it?

the normal process to make the laminations is punching but tooling costs for punching are high. For a very short run profile cutting is probably cheaper, call around your local firms that do plasma/waterjet/laser cutting and get some quotes. Generally you just need to provide a dxf. You may have to source the steel yourself as they probably won't stock it.

Just contact a local machine shop and ask for a quote. You'll need to know what sort of tolerance you need and what materials and finish you want.

@fahraynk - I regularly get small parts laser cut which are so accurate for size that they need no further machining .

Which country are you in ?
