Textile: Sizing Machines and Winding Machines

A lot of textile machines that are old, have an unreasonable cost for repairing and maintenance, especially for analogue DC Drives and Motors, electromechanically relays and variable torque gears (PIV).

For the first time in Iran, this company (NASE) has replaced DC Drives and motors with Digital AC Drives and motors without using PIV, and has replaced electromechanically relays with intelligent relays and PLC, it means more redundancy, lower cost in spare part and maintenance.
