FAQ
Q1: What is the Allen-Bradley MPL-B320P-RJ72AA used for?
A1: This servo motor is designed for industrial automation applications requiring controlled rotation, accurate positioning, and consistent speed. Typical uses include packaging machinery, material handling equipment, automated assembly systems, and manufacturing lines.
Q2: What is the rated speed of the MPL-B320P-RJ72AA?
A2: The motor has a rated speed of 5,000 RPM. Its high-speed capability makes it suitable for motion control systems that require fast and repeatable movement.
Q3: What type of feedback does this servo motor use?
A3: The MPL-B320P-RJ72AA uses a 2-pole resolver to provide rotor position feedback. Resolver-based feedback is commonly used in industrial servo systems where reliable position detection is important.
Q4: Does the MPL-B320P-RJ72AA have an integrated holding brake?
A4: No. This model does not include an integrated holding brake. If the application requires the shaft to remain stationary when the motor is de-energized, an external braking or mechanical holding solution may be required.
Q5: What type of shaft does the MPL-B320P-RJ72AA have?
A5: It features a keyed shaft extension. The keyway allows the motor to connect to compatible couplings, pulleys, and other mechanical transmission components designed for keyed shafts.
Q6: Which connector is used on the MPL-B320P-RJ72AA?
A6: This model uses a right-angle SpeedTEC DIN connector that can rotate through 180 degrees. This arrangement provides flexibility when routing cables in compact machine installations.
Q7: What are the dimensions and weight of the MPL-B320P-RJ72AA?
A7: The motor has a 100 mm frame size and a 50.8 mm magnet stack length. Its approximate listed weight is 3.86 kg (8.50 lbs). For exact overall length, shaft dimensions, and mounting measurements, refer to the manufacturer’s mechanical drawing.
Q8: What should be checked before replacing the MPL-B320P-RJ72AA?
A8: Confirm the full model number, voltage rating, rated speed, resolver compatibility, keyed shaft dimensions, connector orientation, and mounting arrangement. Also verify that the replacement motor is compatible with the existing servo drive and control system before installation.
