8LSA25.E5060C200-3 by B & R Automation

The 8LSA25.E5060C200-3 is a three-phase synchronous motor produced by B & R Automation within the 8LS Synchronous Motors series. Classified under the 8LSA designation, the unit follows the standard configuration without a reinforced bearing. It is intended for dynamic positioning and speed control in automated machinery where a compact flange-mounted drive is preferred. By integrating an optical feedback system and a built-in holding brake, the motor supports motion generation and secure axis retention on medium- to high-speed industrial axes.

Its nominal rotor speed reaches 6000 rpm, enabling direct coupling to fast transfer shafts without intermediate gearing. Thermal management relies on self-cooling through free circulation, so airflow around the housing must remain unobstructed for continuous duty. A flange diameter of 58 mm provides the interface for compact mounting arrangements in pick-and-place stations and similar machinery. Position feedback is delivered through an optical EnDat encoder that communicates with version 2.1, giving purely digital position data to the drive. The shaft is smooth, which avoids keyway stress concentrations, and length code 5 indicates the stator stack depth used for this motor.

The encoder resolves motion into 13/12 bits for single-turn and multi-turn data and records up to 4096 revs of turn count, allowing absolute position recovery after power loss. A standard holding brake supplies static torque for vertical or safety-critical axes, while the electrical interface exits through a straight top connector that helps maintain clearance around adjacent equipment. Revision 3 identifies the current production release. Because an oil seal is not present, external sealing must be provided by the surrounding machine. The stator winding layout remains matched to the motor's intended torque range.
