Product Description:

The 8LSA45.E1030D300-3 is a synchronous servo motor manufactured by B&R Automation within the 8LS Synchronous Motors series. It functions as a precision drive component, translating the controlled output of a servo inverter into repeatable rotary motion for packaging lines, assembly gantries, and other industrial automation equipment that rely on tight velocity and position control. As part of the 8LSA designation, the unit is intended for applications where compact size and integrated feedback are preferred over external encoders.

The motor follows the 8LSA configuration and uses a standard rotor without reinforced bearings. It reaches a rated speed of 3000 rpm through its three-phase synchronous design and length-code 5 stack. A square mounting flange measuring 100 mm registers the housing to the machine frame, while self-cooling and free air circulation dissipate heat without external blowers. Position data comes from an optical EnDat sensor, and power and feedback conductors leave the stator through an angled swivel connector that simplifies cable routing. The keyed shaft mates directly with couplings, and the absence of an oil seal reduces friction to support a higher dynamic response. Product revision 3 indicates minor internal enhancements that do not affect the motor’s form or mounting arrangement.

Feedback capabilities extend beyond a single-turn reference. EnDat version 2.1 supports fully digital communication, delivering absolute position with 13/12-bit resolution and maintaining continuous multi-turn tracking for up to 4096 revolutions without losing its reference position. A standard holding brake engages whenever DC power is removed, keeping loads stationary during emergency stops or service procedures. The absolute feedback system allows the motor to return precise position data immediately after power is restored, simplifying startup and diagnostic routines in complex motion assemblies.
