The
CARTRIDGE 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 full frame motor.
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 engages the rotor to the load and the frame
of the CARTRIDGE DDR™ mounts to the machine with a bolt circle and pilot
diameter just like a conventional servo motor saving space and design time and
simplifying the overall system.

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 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 less than 30 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.
Inertia
matching
Since the CARTRIDGE DDR™ motor is directly connected to the machine,
inertial matching is not required as it is on a conventional motor. With direct
drive, inertia miss match of 250 to 1 is common and miss match of 800 to 1 has
been implemented.
Mounting Orientation
The CARTRIDGE DDR™ motor can be mounted with any orientation
including either a horizontal or vertical shaft.
A smart concept

It is a simple and quick procedure to mount a CARTRIDGE DDR™ motor to a machine:
Slide the CARTRIDGE DDR™ motor onto the shaft
Bolt the housing to the machine frame
Torque the compression coupling
Unbolt the shipping clamp hardware and store it in the provided slots
Connect cables between the CARTRIDGE DDR™ and the SERVOSTAR® series drive amplifier
Commence operation
The CARTRIDGE DDR™ motor can easily go from the shipping container to full operation in less than 30 minutes. This innovative design represents a quantum leap over the days of engineering, installation, and alignment required for Frameless DDR motors.

Torque density
Proprietary electromagnetic design gives CARTRIDGE DDR™ motors up to 50% more torque per motor volume than conventional DDR technology.

Features
Two frame sizes, 246mm and 350mm
Three stack lengths in each frame size
Continuous torque from 50 to 510 Nm
Peak torque from 120 to 1017 Nm
Absolute position sine encoder with maximum resolution of 2,097,152 counts per revolution
One drive amplifier, the SERVOSTAR® drives the standard CARTRIDGE DDR™ product line
UL and CE agency certifications are standard
High energy permanent magnet brushless DC configuration utilizing a proprietary electromagnetic design gives CARTRIDGE DDR™ motors more torque per volume than conventional DDR technology.
Options
480 VAC high voltage option expands the speed range. 230 VAC windings available, too.
High speed winding option for the 13 frame size connected to the SERVOSTAR® 640 drive amplifier extends the speed range of the larger frame motor.
Hollow shaft option provides a 32mm through bore to allow process or wiring to run through the center of the motor. Provision for mounting a rotary union to the shaft and housing is included. Available July 2004.
Technical Data
Nominal values at 40°C ambient temperature and 110 K temperature rise in the windings motor mounted to a reference mounting plate. Modern motors with compact designs may exhibit high surface temperatures, requiring a de-rating from the nominal values in some applications.
