Cartridge DDRThe 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:

bullet

Slide the CARTRIDGE DDR™ motor onto the shaft

bullet

Bolt the housing to the machine frame

bullet

Torque the compression coupling

bullet

Unbolt the shipping clamp hardware and store it in the provided slots

bullet

Connect cables between the CARTRIDGE DDR™ and the SERVOSTAR® series drive amplifier

bullet

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.

Options

bullet

480 VAC high voltage option expands the speed range. 230 VAC windings available, too.

bullet

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.

bullet

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.
