Product Description:

The 8LSA57.E0022D100-0 is a three-phase synchronous motor built by B&R Automation for the 8LS Synchronous Motors series. It converts electrical power from a servo drive into precise rotary motion for positioning or continuous-duty axes in automated machinery. The 8LSA configuration indicates a standard build that omits reinforced bearings, making the unit suitable for moderate radial loads while keeping inertia low for dynamic response in packaging, assembly, and material-handling stations.

A square mounting interface of 142 mm on the flange determines the space required on gearboxes or machine frames. The rotor can reach a rated speed of 2200 rpm, so drives can command medium-to-high process velocities without approaching mechanical limits. Thermal energy is removed through self-cooling with free air circulation, meaning airflow over the housing is sufficient and no external blower is needed. Position feedback is provided by an optical EnDat encoder whose differential signals allow noise-resistant transmission over shielded cables. Inside the encoder, the scale delivers 13/0 bits of single-turn and multi-turn resolution, giving the controller enough granularity for smooth velocity loops and accurate absolute homing.

Compatibility with drive firmware is provided through EnDat version 2.1, allowing automatic parameter uploads and electronic nameplate functions. Power and feedback plugs are easy to orient because the motor has angled swivel connections that can be rotated during installation. Torque is transferred by a shaft end with a key, ensuring positive engagement with couplings or pulleys. A pre-machined mounting flange streamlines assembly and aligns the stator concentrically with adjoining equipment. Length code 7 indicates the magnetic stack depth for this frame size, and the design omits a holding brake and oil seal to minimize mass when axial sealing or static holding torque is unnecessary.
