Open Source Electric Motor Analysis of Industry Standards

OSE Work

• Dirk Log - built and run a 3D printed axial flux motor successfully, with Michel's motor as inspiration
• Michel Log - designed a 3D printed axial flux motor

Open Source Projects

• 3D Printed Electric Motor
• ODrive - open source, low cost 3 phase motor drive (utilizes rotary encoder)
• VESC - advanced, open source, 3 phase motor drive, industry standard performance
• 3D Printed Stepper Motor
• 3D Printed Wind Turbine Blades
• Open Source Wind Turbine

Discovery - Companies in the Open Source Space

• Motor Design Limited - [1] - Website - [2]. These guys reverse engineer motors, so may be useful.

Cars

• Riversimple - seminal hydrogen car by Hugo Spowers.

Individuals

• Axial Flux motor - but Github repo is empty. MIT License. - https://evnerds.com/electric-vehicles/electric-car-news/open-source-axial-hub-motor-for-electric-cars-and-motorcycles/

Analysis Software - Open Source

• This guy wrote an open source package for motor design for Matlab or Octave, can be ported to FreeCAD - [3]

Controllers

• World class is open source already by Benjamin Vedder - VESC - [4]

Motor Types

• AC capacitor start - 5hp motor
