Kollmorgen pioneered the development of direct drive technology, and today offers the broadest range of direct drive motors in the industry.

Mechanical transmissions — such as gearboxes, timing belts, pulleys or lead screws — increase machine size, weight and noise while introducing backlash and mechanical losses that reduce machine performance. Direct drive rotary and linear servo motors eliminate all these issues.

Kollmorgen DDR housed rotary,CDDR cartridge rotary and DDL linear direct drive motors mount directly to the driven load, delivering industry-leading performance with improved accuracy, higher throughput, greater reliability and smooth, quiet operation to suit a wide range of machine-design needs.

Direct drive rotary and linear servo motors improve load acceleration, lower power consumption, reduce system inertia and ensure the greatest precision. And because direct drive motors eliminate the need for transmission components, your motion system is easier to integrate and practically maintenance-free. No gearbox to lubricate, no belts to tighten, no cams to wear — plus a dramatically increased mean time between failures (MTBF).

Cartridge Direct Drive Motors - Kolmorgen

Cartridge DDR® >

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.

Housed DDR Medium

Housed D & DH >

Housed DDR servomotors offer high torque density, precise performance and zero maintenance in an easily installed servo solution.

Direct Drive Linear Motors

Direct Drive Linear 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.
