Product Description:
The 8LSA35.E2030D200-0 is a servo motor manufactured by B & R Automation for the 8LS Synchronous Motors series. It translates three-phase drive current into precise torque and speed so that packaging stations, assembly robots, and material-handling conveyors can follow tightly regulated motion profiles. Compact windings, an integral feedback interface, and a sealed stator housing allow the motor to connect directly to B & R inverters, delivering closed-loop performance while requiring minimal cabinet space.
The configuration tag 8LSA identifies the standard motor build for general machine axes. Power and feedback leads exit through an angled, swiveling cable outlet and terminate at a field-serviceable connector, simplifying cable routing inside cramped enclosures. Cooling relies on self-cooling with free air circulation, eliminating the need for external blowers or liquid jackets. A face dimension of 91.3 mm on the mounting flange aligns the frame with compatible gearboxes, while the flange mounting pattern streamlines installation on base plates and linear stages. The motor has a smooth shaft without an oil seal, so it should be installed where lubricant cannot migrate toward the front bearing or enter the motor housing. This shaft arrangement also supports direct attachment to clamping couplings where a keyed connection is unnecessary.
Axis holding is provided by a standard holding brake that clamps the rotor whenever supply power is removed. The magnetic stack uses length code 5 to balance continuous torque with moderate inertia, supporting midrange feed drives without excessive overshoot. A three-phase synchronous winding allows the controller to regulate stator fields precisely, and nominal operation reaches 3000 rpm for direct coupling to gearboxes or belt pulleys. The motor does not have reinforced bearings, which limits the permissible radial load on the shaft. Belt tension and overhung mass should therefore remain within the applicable mechanical limits during installation. Proper shaft alignment helps prevent unnecessary bearing stress when the motor drives a pulley, gearbox, or rigid coupling.
