Product Description:

The 8LSA25.E5060D200-3 is a three-phase synchronous servo motor produced by B & R Automation for the 8LS Synchronous Motors series. Identified as an 8LSA motor, the unit is supplied in a standard configuration without reinforced bearings and is secured to the machine by a mounting flange. The motor delivers tightly regulated rotary motion to packaging, handling, and assembly stations that rely on closed-loop speed and position control. Its permanent-magnet design supports responsive torque generation, while electronic commutation allows the connected drive to regulate motion accurately across changing loads and operating speeds.

Its maximum mechanical speed is 6000 rpm, so drive parameters must accommodate this upper limit when planning acceleration ramps. Position feedback is provided by an optical EnDat encoder that communicates using EnDat version 2.1, enabling absolute position capture immediately after power-up. The encoder provides 13-bit single-turn resolution and 12-bit multi-turn resolution, supplying fine position data for interpolated motion and retaining the shaft position across multiple revolutions. This multi-turn capability covers 4096 revolutions, eliminating the need for an external reference switch after an extended shutdown. Mounting is aided by a square flange measuring 58 mm, which matches compact gearboxes and couplings commonly used on small- to medium-frame machines.

For thermal management, the motor uses self-cooling with free air circulation, so ambient airflow around the housing must remain unobstructed. Power and feedback cables exit through an angled swivel connector housing that can be rotated to support practical cable routing, and the mating side uses a standard industrial connector to simplify harness assembly. A standard holding brake secures the load when the drive is disabled, while the smooth shaft end supports backlash-free coupling with a clamped hub. The motor has length code 5, indicating its housing length within this frame range. It is supplied without an oil seal, so the shaft interface should be protected from lubricants and other liquids where necessary. The unit is designated Product Revision 3.
