Innovation propels the Kollmorgen ServoDisc Series ahead, redefining motion control with its groundbreaking ironless disc armature design. By removing traditional iron cores, this servomotor series delivers unmatched performance, significantly reducing weight and rotational inertia. This results in exceptional responsiveness and consistently precise positioning. The series distinguishes itself with remarkable smoothness, eliminating cogging torque to ensure fluid, uninterrupted motion. High-precision operations experience an immediate boost, witnessing improved production quality, greater throughput, and enhanced efficiency. Designed compactly, the ServoDisc seamlessly fits into confined spaces without sacrificing power or functionality. Its versatility makes it ideal for advanced manufacturing, robotics, and high-precision automation environments. The series also excels in thermal management, efficiently dissipating heat to sustain reliable performance even under challenging conditions. Coupled with robust construction, this superior thermal efficiency guarantees longevity and dependable operation in critical, demanding applications.
