Leveraging over 70 years of product innovation, Kollmorgen pioneered the development of direct drive technology. Today, their Direct Drive Rotary (DDR) and KBM Frameless motor solutions offer industry-leading performance, zero maintenance, clean mechanical assembly, improved accuracy, higher throughput, better reliability, and smooth, quiet operation to suit a wide variety of machine design needs. The concept of Direct Drive technology involves replacing conventional servo motors coupled to some form of mechanical transmission such as gearbox, timing belts, pulleys, or ballscrews. Mechanical transmissions introduce backlash, mechanical losses and noise that can reduce machine performance.
In addition, mechanical transmissions increase machine size and weight. Direct Drive motors, either housed (DDR), partially housed (CDR) or frameless (KBM) directly mount to the load to be driven thereby eliminating such challenges and in many cases provides a much more robust alternative. System maintenance is greatly reduced as mechanical parts prone to wear are removed, dramatically improving overall MTBF rates. Improved load acceleration, lower power consumption, reduced system inertia, and higher precision are major advantages that direct drive solutions can provide.
