Abstract:
A servo motor is used as a motor for industrial sewing machines because it produces less noise, consumes less power, and is lightweight. The only disadvantage of the servo motor is its low minimum speed of up to 5000 rpm, which is why the sewing machine cannot be used at high speeds. When working on complex parts or with thick fabrics, slowing down the machine allows for greater accuracy and avoids needle breakage. When the operator works with thinner fabrics and produces more products, the speed of the machine is usually increased. In this paper, a servo motor control system based on PLC S7-1200 is proposed. The system is designed to control the actuators of the machine, such as electromagnets and gas pedals, in addition to the main shaft motor. The comparison shows that the results obtained with the author's control system are identical to those obtained with the control system of the sewing machine JUKI DDL 8700-7.
