AC servomotor Cartridge DDR® series

400 V230 Vframeless

Our exclusive Cartridge DDR® servomotors 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
