Description
Product Name: 1326AB-B720E-21-ML Allen Braley Power module
Product details:
The Allen-Bradley 1326AB-B720E-21-ML is a high-performance AC servo motor from the 1326AB series, manufactured by Rockwell Automation. These motors are designed to meet the rigorous demands of high-torque industrial applications, specifically when paired with Allen-Bradley servo drives like the 1394 or 8520 series.

Product Detailed Description
The 1326AB-B720E-21-ML is a brushless AC synchronous motor featuring rare-earth magnets (Neodymium-Iron-Boron). This construction allows for a high torque-to-size ratio and low rotor inertia, making it ideal for applications requiring rapid acceleration and deceleration.
The “ML” suffix indicates a specialized high-resolution feedback system, which provides precise positioning and velocity control, ensuring the motor can handle complex motion profiles with minimal error.
Key Advantages
- High Power Density: Delivers significant torque in a relatively compact frame size due to advanced permanent magnet technology.
- Thermal Stability: Built with Class F insulation, allowing the motor to operate reliably even in high-temperature industrial environments.
- Brushless Design: Minimizes maintenance requirements and eliminates the risk of sparking, extending the operational lifespan.
- Dynamic Response: The low-inertia rotor allows for “start-stop” cycles at very high frequencies without overheating.
- Seamless Integration: Fully compatible with the Allen-Bradley ecosystem, allowing for “plug-and-play” configuration within Studio 5000 or older drive software.
Important Considerations & Precautions
- Drive Compatibility: Ensure the servo drive firmware supports high-resolution encoders. This motor is typically paired with 1394 Digital Servo Multi-Axis systems.
- Cable Length: Excessive cable lengths between the motor and drive can cause voltage drops or signal interference with the encoder; use shielded Allen-Bradley cables for best results.
- Shaft Loading: Do not exceed the rated radial or axial load limits, as this will lead to premature bearing failure.
- Heat Dissipation: Ensure adequate airflow around the motor housing. While IP65 rated, trapped heat in an unventilated enclosure can reduce the motor’s duty cycle.
Typical Applications
The precision and torque characteristics of the 1326AB-B720E-21-ML make it a staple in:
- Automotive Assembly: Robotic arms, welding positioners, and paint lines.
- Material Handling: High-speed conveyors and sorting systems.
- Packaging Machinery: Form-fill-seal machines and palletizers.
- Machine Tools: CNC milling, boring, and grinding feed axes.
