General

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.

The motor brings a quantum leap when compared to any other direct drive configuration:

• Cost effective and easy to mount
• Saves months of engineering and days of installation of a frameless motor and feedback device
• CARTRIDGE DDR™ requires a simple shaft and pilot configuration and less than 30 minutes from shipping container to operation.

Inertia matching

Since the CARTRIDGE DDR™ motor is directly connected to the machine, inertial matching is not required as it is on a conventional motor. With direct drive, inertia miss match of 250 to 1 is common and miss match of 800 to 1 has been implemented.

Mounting

The CARTRIDGE DDR™ motor can be mounted with any orientation including either a horizontal or vertical shaft. It is a simple and quick procedure to mount a CARTRIDGE DDR™ motor to a machine:

Slide the CARTRIDGE DDR™ motor onto the shaft Bolt the housing to the machine frame Torque the compression coupling Unbolt the shipping clamp hardware and store it in the provided slots Connect cables between the CARTRIDGE DDR™ and the servo amplifier Commence operation   Flash demo:  It's so simple to mount Cartridge 05 (5MB), Cartridge 13 (12MB) Live Mounting It's best to download - save locally and play later: Install (42 MByte) Remove (25 MByte)
