Cartridge DDR®


Kollmorgen´s 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
