MPL-B320P-MJ74AA Low-Inertia Servo Motor

High-Performance Servo Motor for Precision Motion Control

Technical Specifications

Main Features and Advantages

Precision Motion Performance: The A-B MPL-B320P-MJ74AA delivers exceptional dynamic response with its low-inertia design (0.0012 kg·m²), enabling rapid acceleration/deceleration for high-throughput applications. The 20-bit absolute encoder provides precise position feedback with ±20 arc-second accuracy, ensuring repeatable motion control in demanding manufacturing processes.

Robust Industrial Construction: Engineered for continuous operation in harsh environments, this servo motor features IP65-rated protection against dust and water ingress. The keyed shaft with integrated seal prevents lubricant migration, while the heavy-duty bearings withstand radial loads up to 220N and axial loads up to 110N, ensuring longevity in high-vibration applications.
