English is not may native idiom, many times is hard to express ideas specially this, where I am not a specialist.
I post here a non conclude excel table, where I figure how generate embroidery G code and how works, needle speed motor always be variable because must be in accord to hoop speed and travel distance.
For begins work I think to use a stepper for needle like a spindle and control it using step and dir motor. How we don't need highest speeds I think that a stepper is enough for 500-550 RPMs and is possible speed drive by Mach and CNC controller. If I will use a AC/DC motor, then I must find a PWM card for speed controll and I don't have it right now. I think go step by step and don't spend money unnecessarily.
I must test this system, but I think than can be usable.
Thanks for all help than can give me.
Sorry my bad english
