Direct Drive Motor

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.

Direct Drive Motors
 Housed_DDR_Medium
Kollmorgen Housed Direct Drive Rotary (DDR) motors offer high performance and zero maintenance in a precision servo solution. These motors combine large diameter, short length and a high number of magnetic poles to provide outstanding torque density, while eliminating the need for gearboxes, timing belts and other transmission components. Our co-engineering capabilities ensure a right-fit solution for your application.
