Description
The A-B MPL-A320P-MJ74AA is a low-inertia brushless servo motor manufactured by Allen-Bradley (A-B), a brand under Rockwell Automation. This motor is designed for industrial automation applications requiring precise control of speed and positioning, particularly those benefiting from rapid starts and stops.
Here’s a breakdown of its key features and specifications based on information gathered from various sources:
Features:
- Low Inertia: Enables fast acceleration and deceleration for applications needing high responsiveness and precise positioning, especially with frequent starts and stops.
- Permanent Magnet Design: Offers several advantages over DC brushed motors, including:
- Higher efficiency and lower maintenance due to the absence of brushes.
- Smoother operation and reduced torque ripple for improved control.
- Multi-Turn Absolute Encoder (Possible): May integrate a high-resolution absolute encoder that provides the motor’s exact position information at any time. This eliminates the need for homing procedures during startup.
- SpeedTEC DIN Connector: Offers a quick-connect and easy-to-assemble power connection.
- Keyed Shaft: Provides a secure connection between the motor shaft and the driven load (e.g., gearboxes, couplings).
- 24V DC Brake (Possible): Some variations might include a built-in DC brake that helps hold the motor shaft stationary when power is removed, improving safety and machine control. Availability depends on the specific variant within the MPL-A320P-MJ74AA series.
Specifications (Based on Available Information):
+
- Frame Size: Likely 100 mm (diameter) based on common MPL-A series models
- Voltage: 230 V AC
- Speed: Up to 5000 RPM (rotations per minute)
- Torque: Specific torque value depends on the motor’s datasheet, which might not be readily available online.
- Brake: Inclusion of a 24V DC brake depends on the specific variant (presence or absence can’t be confirmed without additional information).
Applications:
- Machine Tools: Precise positioning of cutting tools in CNC machines, lathes, milling machines, etc., especially for applications with frequent tool changes or rapid movements.
- Robotics: Joint actuation in robots for various industrial tasks like assembly, welding, material handling, and pick-and-place operations that require fast and precise movements.
- Indexing Applications: Precise positioning of components or materials in assembly lines, packaging machines, and other industrial processes.
- Material Handling Systems: Controlled movement of materials in high-speed sorting machines, conveyor systems with frequent starts and stops, and automated guided vehicles (AGVs).
