Leveraging over 70 years of product innovation, Kollmorgen pioneered the development of direct drive technology. Today, our Direct Drive Rotary (DDR), Direct Drive Linear (DDL) 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.
Kollmorgen offers many standard platform products and options; however we excel in working with our customers to develop direct drive solutions tailor made to meet specific performance and size requirements. Our capabilities range from minor modifications of catalog products to completely new ‘clean sheet’ designs. Kollmorgen direct drive solutions provide value added benefits at very competitive pricing that allow our customers to differentiate their machines in the marketplace.
Our exclusive Cartridge DDR® servomotors combine the performance advantages of a frameless motor with the ease of installation of a full-frame motor. The advanced electromagnetic design provides up to 50 percent more torque density than comparably sized conventional servo motors.More about Cartridge DDR® >>
Housed DDR servomotors offer high torque density, precise performance and zero maintenance in an easily installed servo solution.More about Housed D & DH >>
The KBM™ series offers high performance, long life and simple installation in a motor kit that can be embedded directly in your machine design.More about KBM Series Frameless >>
The RBE Series from Kollmorgen is a proven platform offering many years of direct drive motor solutions. As the saying goes, these motors are ‘oldies but goodies’ and continue to be viable solutions where relatively high torque and low speed, pancake type motor configurations are required.More about RBE >>
While these direct drive rotary servomotors are not available for new applications, Kollmorgen continues to provide replacement motors and support for existing customers.More about Serviced Motors >>
A Direct Drive Linear (DDL) motor is basically a rotary motor that is laid out flat and directly coupled to the driven load, eliminating the need for ball/lead screws, rack and pinions, belts/pulleys and gearboxes.More about Direct Drive Linear >>
