CARTRIDGE Direct Drive Rotary™ Motors
The CARTRIDGE DDR™ motor is the newest addition to the Kollmorgen line of DDR products. The CARTRIDGE DDR™ motor does not have bearings. It mounts to a machine using the machine’s existing bearings to support the motor’s rotor. The frame of the CARTRIDGE DDR™ motor mounts to a pilot and bolt circle on the machine frame much like a conventional motor. The rotor engages to the load using an innovative compression coupling, which effectively makes the motor’s rotor and the load one piece, eliminating any compliance between the motor and the load.
The CARTRIDGE DDR™ motor brings a quantum leap in cost effectiveness and ease of application when compared to any other direct drive configuration. Compared to the months of engineering and days of installation of a frameless motor and feedback device, the CARTRIDGE DDR™ requires a simple shaft and pilot configuration and as little as 5 minutes from shipping container to operation. Thanks to the CARTRIDGE DDR™ motor, a significantly broader range of motion applications will benefit from the performance and reliability advantages of direct drive.
