Step servo and stepper control system for Auto-Screw driving Machine
Introduction
The traditional way to lock the screw is by hand , which is low efficiency.Now the manufacturer developed Auto-Screwdriving Machine for locking the screw,this machine can meet the high efficiency and high accuracy requirement from factories.it is a main part of automatic production line.
The Key features requirement for the drive and motor
1.This kind of no interpolation requirement ,just position to position , it must move fast and positioning accurately
2.the assembling space is small, that is not good for cooling, so the drive and motor should be low heating
3.low noise
