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.

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.
