A self lubricating ball screw has been successfully tested for over 20000 hours continuous operation.
CE marked and UL listed for global application, Cartridge DDR motors feature pre-engineered components, an integrated, factory-aligned high resolution feedback device and a unique bearing-less design that facilitates 'mount and run' operation in under than 30 minutes - compared to weeks, or even months, of design and integration time common to existing frameless direct drive systems.
Cartridge DDR motors also feature an advanced electromagnetic design that provides up to 50% more torque density than comparably sized conventional servomotors.
Conventional servo systems typically include a number of mechanical transmission components that limit the performance and reliability, and drive up costs of operation of these systems.

Low-noise linear actuator has a long stroke
As industry focuses on the working environment it should welcome a long stroke linear actuator that has a very low operational noise profile.
Cartridge DDR motors eliminate all mechanical transmission parts resulting in: * Simplified installation (<30 minutes) - just mount motor and connect cables * Increased machine uptime by virtue of maintenance-free operation * Quieter operation by eliminating the transmission (up to 20db reduction) * Increased accuracy (up to 50 times greater) * Zero maintenance - no life cycle cost Because of their unique low-cost design, Cartridge DDR motors are competitively priced when compared to traditional servo systems with mechanical transmissions.
Even with a slightly higher initial cost, over a 5-year period of use Cartridge DDR motors will reduce operating costs by more than $10,000 on a single axis of motion when compared to conventional systems.
Danaher Motion believes the lower cost of entry coupled with the greater lifecycle savings offered by the Cartridge DDR motor will accelerate the adoption of direct drive technology for new machine designs in industries such as converting, packaging, printing, semiconductor and factory automation.
Cartridge DDR motors are available in two frame sizes, with three stack lengths per frame.
Voltage ratings are available in 230V, 400V, and 480V for maximum design flexibility and robust operation.
They provide 50 to 510Nm continuous torque, peak torque to 1100Nm, and speeds to 1200 rpm.
