I have seen some servo injection moulding machines that have multiple servo motor and I am confused about that.
because as far as I know we use servo motor to determine the speed of motor as consequence we have energy saving for those time that
we don't need pressure and also other advantages that a servo system bring us. but why multiple servo motor do we need?
are these motor drive different part of machine or based on the pressure each motor come to our circuit and help us to attain
max power. if you have some datasheets or useful information, I would be appreciate to reference it .
