Cartridge Direct Drive Rotary (DDR ) Motor

            The Cartridge DDR  Motor is the first in the industry to combine the space-saving and performance advantages of frameless
            DDR technology with the ease of installation of a full-frame motor. Cartridge DDR motors also feature an advanced
            electromagnetic design that provides up to 50% more torque density than comparably sized conventional servo motors.
            Consisting of a rotor, stator, factory-aligned high-resolution feedback device, the Cartridge DDR motor uses the machine’s
            bearings to support the rotor. An innovative compression coupling secures the Cartridge DDR’s rotor to the machine shaft, and
            the Cartridge DDR’s housing is bolted to the machine frame with a bolt circle and pilot – just like a conventional servo motor.
            Also, mechnical transmission components are eliminated, saving space and design time while simplifying the overall system.
