Key Product Advantages
- High Power Density: The 1326AB series utilizes rare-earth magnets (Neodymium-Iron-Boron), providing exceptional torque in a compact frame.
- Low Maintenance: As a brushless design, it eliminates the wear and tear associated with brushes and commutators, ensuring a longer service life.
- Precision Control: The integrated 2000-line encoder provides high-resolution feedback for precise positioning and smooth velocity control.
- Rugged Construction: Built to withstand harsh industrial environments, featuring an IP65 rating and heavy-duty bearings.
- Seamless Integration: Fully compatible with Allen-Bradley 1394 and 1391 servo drives, allowing for “plug-and-play” configuration in Rockwell Automation ecosystems.
Product Applications
This motor is ideal for high-cycling applications requiring rapid acceleration and deceleration:
- Packaging Machinery: High-speed labeling, filling, and wrapping.
- Material Handling: Robotic arms, pick-and-place systems, and automated sorters.
- Machine Tools: CNC milling, grinding, and specialized metalworking equipment.
- Textile Industry: Precision looms and fabric cutting machines.
- Printing Presses: High-speed paper feed and alignment.
Important Considerations & Precautions
Note: Proper installation and maintenance are critical for the longevity of high-performance servo motors.
- Heat Dissipation: Ensure the motor is mounted on a heat-conductive surface. If the motor exceeds its rated temperature, the magnets can lose their magnetism permanently.
- Shaft Loading: Avoid excessive radial or axial loads on the shaft. Over-tightening belts or misaligning couplings can lead to premature bearing failure.
- Cable Integrity: Use only shielded cables to prevent EMI (Electromagnetic Interference) from affecting the encoder signal.
- Brake Usage: The integrated 24V DC brake is a holding brake, not a dynamic brake. It should only be used to hold a position when the motor is stopped, not to stop a motor in motion (except in emergencies).
- Encoder Sensitivity: The encoder is a delicate optical component. Avoid hitting the motor housing or shaft with hammers during installation.
