Product Description:

The 8LSA84.S1030D200-0 is a three-phase synchronous motor produced by B & R Automation for the 8LS Synchronous Motors series. Within an automation cell, the unit converts electrical power from a servo drive into rotational motion for positioning or continuous-duty tasks. The 8LSA designation indicates a standard configuration without reinforced bearings, so the motor is intended for general machine axes rather than applications with high radial loads.

The motor has a rated speed of 3000 rpm, giving the drive system a balance between torque density and mechanical throughput. Its mechanical interface uses a 240 mm square flange, allowing direct attachment to compatible gearboxes or machine frames. Heat is removed through self-cooling with free circulation, so external fans are unnecessary and airflow requirements remain simple. Position feedback is provided by an optical EnDat 2.2 encoder, and its data stream carries absolute single-turn and multi-turn position information with a 25/12-bit resolution for precise interpolation in servo loops. Length code 4 indicates the stator stack depth selected for the S1030 winding, while conventional bearings help keep rotor inertia moderate.

Power and feedback conductors exit through an angled swivel connector, allowing cable ducts to follow the machine contour without sharp bends. A standard holding brake secures vertical or suspended loads when power is removed, while the lack of an oil seal reduces friction in clean environments. The motor uses a smooth shaft, making it compatible with clamp couplings or shrink disks where minimal backlash is required. Its encoder provides a multi-turn capability of 4096 revolutions, allowing the control system to retain absolute position across numerous shaft rotations. This position tracking supports restart after a power cycle without requiring the axis to repeat a mechanical homing sequence.
