got some 5 pahase motors and combined controller with 5 pahase drives
one was a stock style of 3 axis mill
motors cales and controller with drives in ine unit

another similar set but 4 axis came from a wire cutter

cheap enough
its rs232 input - seems simple enough, but i had lots of 4 phase stuff and a fewof them network nvm controllers and loads of 4 phase motors and lotsof cheap drives
so i went that way

they are really nice high quality stuff
