The Cartridge Direct Drive Rotary (DDR) motor is the first in the industry to combine the space-saving and performance advantages of frameless DDR technology with the ease of installation of a fullframe motor. Cartridge DDR motors also feature an advanced electromagnetic design that provides up to 50% more torque density than comparably sized conventional servomotors.

Consisting of a rotor, stator and factory-aligned high-resolution feedback device, the Cartridge DDR motor uses the machine’s bearings to support the rotor. An innovative compression coupling secures the Cartridge DDR’s rotor to the machine shaft, and the Cartridge DDR’s housing is bolted to the machine frame with a bolt circle and pilot – just like a conventional servomotor – saving space and design time and simplifying the overall system.

The original mechanical transmission system comprises 2 bracket pieces, 12 bolts, 2 pulleys, 2 set screws, 2 keys, a timing belt, a housing to protect operators from the timing belt, a tension system for the timing belt, and motor/gearhead. With the Cartridge DDR system, this is all replaced by the motor and 4 mounting bolts, resulting in fewer parts to maintain and cost savings.

The best planetary gearheads have a backlash between 1 and 2 arcminutes. Over the life of the gearhead, the backlash will increase. The Cartridge DDR system has an absolute accuracy of 26 arc-seconds and a repeatability of 0.7 arc-seconds. The press feed machine with the Cartridge DDR has a feed accuracy of +/- 0.0005 inch where the press feed machine with the mechanical transmission has a feed accuracy of 0.002 inch. Therefore, there was an overall four times improvement in machine accuracy with the Cartridge DDR system.
