Kollmorgen Cartridge DDR® Servo Motors

Cartridge DDR®

Our exclusive Cartridge DDR® servo motors combine the performance

advantages of a frameless motor with the ease of installation of a

full-frame motor. They feature an integrated, factory-aligned high

resolution feedback device and a unique bearingless design that couples

directly to the load, using the machine’s own bearings to support the

rotor. Most models can be installed in under five minutes.

Features

• 5 frame sizes, multiple lengths

• 230 / 400 / 480 VAC windings available (high and low)

• 4.5 to 510 N-m (3.3 lb-ft to 376 lb-ft) continuous torque accommodates

a wide range of high-power application requirements

• Speeds up to 2.500 rpm meet most medium speed and high torque

application requirements

• Power ratings from 775 to 11.700 watts meet high power demands for

most applications

• Integral sine encoder feedback provides resolution of over 134 million

counts per revolution

• Built-in thermistor provides over-temperature protection

• UL Listed for global acceptance

Benefits

• Provides the space-saving and performance advantages of a frameless

DDR motor with the ease of installation of a full-frame motor

• Integrated compression coupling and shipping hardware: eliminates parts

and labor for a faster, lower-cost machine build

• Installs in 5 minutes

• Up to 50% more torque density than comparably sized conventional servo

motors

• Direct load connection eliminates backlash, compliance and maintenance

of gearboxes, belts or pulleys

• Low cogging for smooth low-speed rotation

• Zero backlash and compliance provides more responsive system performance

• Pre-configured amplifiers and feedback devices simplify installation and startup
