Machine Having 06Servo Vs Machine Having 48Servo Motors

Hi;

 

In these days, our management is working to buy another new flexo printing machine from a Swedish company. The existing machine has a main DC motor 49KW which drives a long shaft. Rotating parts of each unit (feeder, printing, slotting, die-cutting folding counter ejector) are attached with this shaft via gear boxes.

 

In selection of new machines, we have two options;

First machine, each unit (feeder, printing, slotting, die-cutting folding counter ejector) has a main servo motor and then timing belts to rotate rotating part of individual unit. For example, in feeder unit, there are five rolls which are attached with gear box. And thus 06nos synchronized servo motors (excluding other almost 48 small AC setting motors) instead of one main motor.

 

In second machine, all the rotating parts of machine have their own individual servo motor. And thus total 48 synchronized servo motors (excluding other almost 48 small AC setting motors) and no any gear box.

 

For me, the machine having 06servo motor is better than that machine having 48servo motors because when we increase the no-of motors, problems are also increased. What do you think? Please dont consider the cost, just a technical question.
