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.
