Product Details
Applications in Paper Folding Equipment
This integrated servo motor series is specifically designed for the high-frequency start-stop and precise fold-positioning demands of paper-folding machines. Its compact all-in-one construction saves valuable internal equipment space, allowing easy installation in tight locations. Low cogging torque ensures consistent fold-line accuracy, while high dynamic response reliably handles hundreds of start-stop cycles per minute. With support for multiple mainstream communication protocols and compatibility with various control systems, plus a fully sealed enclosure that withstands paper-dust environments, this motor series helps folding equipment achieve long-term stable and efficient operation.
