Direct Drive Linear and Rotary Motors

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

Mechanical transmission, such as gearboxes, timing belts, pulleys or lead screws, introduce backlash, mechanical losses and objectionable audible noise that can reduce machine performance, increase machine size and weight.

Direct Drive motors, either housed rotary (DDR), cartridge rotary (CDDR) or frameless (KBM high-voltage rotary or TBM low-voltage rotary or DDL linear motors) directly mount to the load to be driven thereby eliminating the transmission, providing a much more robust alternative (Want to know more about frameless motors? View our What is a Frameless Motor? page). System maintenance is greatly reduced as mechanical parts prone to wear are removed, dramatically improving MTBF. Also improved are load acceleration, lower power consumption, reduced system inertia, and higher precision are major advantages that direct drive solutions can provide.

 

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.

KBM Series Frameless

The KBM series offers high performance, long life, simple installation in a motor kit that can be embedded directly in your mechanical design. A huge selection of standard motors and cost-effective modifications ensure a perfect fit.

TBM Series Frameless

Our TBM series provides direct drive frameless motors designed to be directly embedded in the mechanical structure of your systems, minimizing weight, size and inertia without sacrificing performance.

RBE Series Frameless

The frameless configuration of these relatively high-torque, low-speed, pancake-style motors eliminates shaft, bearings, endbells and couplings for reduced volume, weight and complexity when integrated directly with the load.

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.
