B&R 8LSA44.EA030D000-3 Synchronous servo motor

Description

1. Product Overview

B&R 8LSA44.EA030D000‑3 is a high‑precision synchronous servo motor of the 8LSA series manufactured by B&R (Austria). As a compact industrial‑standard power actuator, it is developed for high‑end automation precision motion‑control applications. Built on the proven 8LS servo motor platform of B&R, this motor delivers high power density, ultra‑low torque ripple, excellent dynamic response and superior positioning accuracy, with a rated power of 200 W for high‑speed precision transmission processes. Featuring a lightweight compact housing, fully‑sealed industrial‑grade protection and maintenance‑free bearing system, it can operate long‑term under harsh factory conditions with continuous heavy‑load cycles, frequent start‑stop actions and high‑speed multi‑axis coordination. Natively matched with B&R ACOPOS servo drive systems, it executes complex processes such as multi‑axis synchronization, interpolation motion and flexible speed regulation. Widely deployed in custom‑built precision automation equipment, 3C‑electronic machinery, packaging machines, new‑energy equipment and precision‑testing instruments, it serves as a core power‑execution component for small‑to‑medium high‑precision automated devices.

2. Core Functions

1. Ultra‑dynamic and precise motion output: Optimized magnetic‑circuit design achieves extremely low torque ripple, smooth start‑stop performance and stable speed operation. The motor responds rapidly to frequent speed and position command changes, meeting sophisticated automation requirements for high‑speed point‑to‑point positioning, continuous trajectory motion and multi‑axis coordinated interpolation, thus improving machining and positioning accuracy.

   
   

2. Compact structure with high power density: The small‑size lightweight design realizes outstanding power‑density performance at 200 W rated power, greatly saving installation space. It fits compact automation layouts and can be easily integrated into various small‑scale precision intelligent equipment for higher system integration and simplified mechanical construction.

   
   

3. Long‑term maintenance‑free stable operation: Two‑side sealed pre‑lubricated grooved ball bearings are adopted. Except for the bearings, no other wearing parts are contained inside the motor, enabling long‑term maintenance‑free service. Heat generated by stator losses is dissipated efficiently through the housing flange, preventing excessive temperature rise and performance degradation during prolonged heavy‑duty operation and supporting 7×24‑hour continuous‑production cycles.

   
   

4. Native closed‑loop servo precision control: Equipped with a high‑precision encoder feedback unit, the motor transmits real‑time data of rotational speed, rotor angle and position back to the ACOPOS drive system to form a fully‑closed‑loop control. Motion deviations are dynamically corrected to eliminate positioning drift and speed fluctuation, ensuring excellent repeat‑positioning accuracy and consistent process results.

   
   

5. Superior environmental adaptability and protection performance: The industrial‑grade fully‑sealed reinforced housing provides vibration resistance, electromagnetic‑interference immunity and wide temperature tolerance. It adapts to workshop environments with dust, light oil contamination and frequent mechanical shocks, satisfying high‑intensity cyclic‑operation requirements of automated production lines with repeated reciprocating movements.

   
   

6. Standardized fast connection and compatibility: Dedicated circular aviation connectors are used for power and encoder signals with well‑defined pin‑outs. Neat wiring and convenient plug‑in connection enable fast installation, commissioning and component replacement for new‑machine assembly, maintenance‑service jobs and production‑line retrofits.

4. Working Principle

The B&R 8LSA44.EA030D000‑3 servo motor follows the standard synchronous‑servo control workflow: receiving drive commands → magnetic‑field commutation drive → high‑precision closed‑loop feedback → dynamic torque adjustment → stable power output. During operation, the B&R servo drive transmits control signals for frequency, voltage and torque. The stator windings inside the motor generate an accurately‑controlled rotating magnetic field which drives the rotor to run synchronously and execute preset speed and position targets. The built‑in high‑precision encoder continuously samples rotor position, speed and angular data and sends feedback signals to the servo drive. The controller compares target values against actual operating data and dynamically adjusts output torque and velocity, completing millisecond‑level closed‑loop regulation to suppress speed oscillation and positioning errors. Supported by the high‑efficiency thermal‑dissipation housing and maintenance‑free bearing system, the motor withstands long‑lasting frequent start‑stop cycles, reciprocating movements and minor overload conditions, delivering precise trajectories and smooth transmission for stable execution of sophisticated automated processes.

5. System‑Architecture Compatibility

This motor is an original standard servo‑actuator from B&R. It features native compatibility with the complete B&R ACOPOS and ACOPOSmulti servo‑drive portfolio with automatic parameter matching, plug‑and‑play functionality and no complex calibration work required, fully fitting the whole B&R motion‑control ecosystem. It can be seamlessly connected to B&R PLCs, motion controllers and host SCADA systems, supporting advanced motion functions including bus‑based multi‑axis coordination, interpolation, electronic cam and synchronous follow‑up control. Standardized mechanical mounting flange and electrical interfaces match conventional automation‑equipment structures, allowing direct drop‑in replacement of older motors from the same series during maintenance, production‑line upgrades and process‑modification projects. With strong system flexibility, it can be easily incorporated into both distributed and centralized automation architectures without modifying the main control logic or mechanical frames, supporting upgrades of both new and legacy equipment.

6. Application Scenarios

Benefiting from compact size, high precision, fast dynamics and maintenance‑free operation, this servo motor is suitable for small‑to‑medium precision automation equipment running high‑frequency, high‑speed and high‑accuracy motion cycles. Typical applications include 3C‑electronic precision‑processing machinery, automated bonding & cutting equipment, high‑speed packaging machines, precision inspection & sorting systems and compact new‑energy assembly devices. It is widely used for processes such as precision point‑to‑point positioning, multi‑axis coordinated trajectory machining, high‑speed reciprocating handling and flexible conveying. Thanks to low‑vibration performance, excellent synchronization, low failure rate and long maintenance‑free service life, it improves equipment accuracy and production throughput while reducing maintenance expenses and unplanned downtime. It represents a preferred servo power unit for small‑to‑medium high‑precision automated production lines and precision intelligent machinery.
