Cartridge DDR Motor
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.
Application Notes
- Bearing Design
- Cogging
- Shaft torsional stiffness
- Tuning - Rotatory Direct Drives
- Measuring the Torque Constant kT
- Wake and Shake
Additional Information
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
