MPL-B4540F-MK74AA Allen Bradley Servo Motor

Allen Bradley MPL-B4540F-MK74AA Servo Motor

Product Description: 

The Allen-Bradley MPL-B4540F-MK74AA is a high-performance, brushless servo motor from the Allen-Bradley MP-Series, designed to deliver exceptional dynamic response and precision in demanding motion control applications. This motor is engineered for seamless integration with Allen-Bradley Kinetix servo drives, forming a complete and optimized motion control solution for complex automation tasks. It is ideally suited for high-throughput applications requiring rapid acceleration and deceleration, precise positioning, and consistent torque, such as in packaging, converting, printing, and advanced material handling systems.

A key feature of this model is its high torque-to-inertia ratio, which enables very fast acceleration and deceleration rates, thereby reducing cycle times and increasing overall machine productivity. The motor incorporates a high-resolution, single-turn or multi-turn absolute feedback system, which provides accurate position data and eliminates the need for a homing routine after power-up. It is built with a rugged, compact design and features a smooth, non-ventilated exterior, making it resistant to contamination from dust and debris. This robust construction, combined with advanced thermal management, ensures reliable operation and long service life in harsh industrial environments.

Technical Specifications:

The Allen-Bradley MPL-B4540F-MK74AA is a 400V class, frame size 45 brushless servo motor. It delivers a peak torque of 5.3 Nm and a continuous torque of 2.3 Nm at a rated speed of 3000 rpm. The motor has a very low rotor inertia, contributing to its high dynamic performance and rapid response to speed and load changes. It operates with a high peak current of 6.3 A and a continuous current of 2.7 A.

This motor is equipped with a high-resolution 24-bit feedback device, which can be configured as a single-turn or multi-turn absolute encoder to provide precise positional data. The motor features an IP65 protection rating, making it fully protected against dust and low-pressure water jets from any direction, allowing for reliable performance in washdown and dirty environments. It is designed with a keyless stainless steel shaft for precise and secure coupling attachment. The motor's construction is non-ventilated (tenacious coating), which prevents the ingress of contaminants and is UL and cUL listed for use in North America, complying with relevant international standards.
