Cartridge DDR

The CARTRIDGE DDR™ motor does not have bearings. It mounts to a machine using the machine's existing bearings to support the motor's rotor. The frame of the CARTRIDGE DDR™ motor mounts to a pilot and bolt circle on the machine frame much like a conventional motor.The rotor engages to the load using an innovative compression coupling, shipping clamp holds the rotor and feedback in place during transportation and mounting.
