ODrive

Basics

• An open source Motor Controller designed to turn hobby brushless dc motors into brushless dc servo motors
• Thus open source and/or hobby level products can use these instead of stepper motors and have the advantages of servo motors
• According to This it is no longer open hardware, only software post v3.4 ?
• How cheap can this be made assuming diy (milled/etched) pcb's ? OTS is ~159.00USD for the board
  • Need to find an older BOM, and do some guestimation
• Also can it be scaled up/down in motors/board, current is two motors per board
  • ie small single on-motor board, piles of motors for a single board -> cnc machine application etc

OSE Replication

Basic Process

Phase 1

• Purchase Board
• Dowload Software, get familiar with it, and find the best software

Phase 2

• Scale Circuitry up to something that can be Milled , or something that can be etched using a pen plotter based mask as well as easily soldered
• Get OSE Board Working to the Same Specs

Phase 3

• Move on to higher specs (higher voltage etc)
• Use OSE Motors
• Make it integrated with the servo motor in a 3d printed or cnc machined case

Phase 4

• Make a workbench in KiCAD to allow adding footprints of an ODrive Module to a Custom PCB on a per - servo basis
