Product Description:
The 8LSA65.EB045D200-1 is a synchronous servo motor engineered by B & R Automation for the 8LS Synchronous Motors series. As a three-phase rotary actuator, it converts drive-controller output into controlled torque and speed for positioning, conveying, and general motion tasks in automated machinery. The motor’s footprint and electrical characteristics match the manufacturer’s modular automation platform, allowing direct integration into packaging lines, assembly cells, and material-handling axes.
The 8LSA housing uses a standard configuration without reinforced bearings, and its self-cooling design relies on freely circulating air instead of an external blower. A mounting flange with a face size of 190 mm centers the unit on gearboxes or machine frames, while a smooth shaft end transmits torque without a keyway. A standard holding brake secures the load while the motor is at rest. Position feedback is supplied by an inductive EnDat encoder with interface version 2.1 and a resolution of 19/12 bits for single-turn and multi-turn position data. The motor reaches a rated speed of 4500 rpm, and its plug-in connector keeps wiring compact by eliminating fixed leads. No oil seal is installed, so the application must provide an external seal if exposure to fluids is expected.
The electrical interface uses an angled swivel connector that can be rotated during installation, easing cable entry in confined spaces. Length code 5 corresponds to the stator stack depth selected for medium torque density within the series. The motor uses a three-phase synchronous design, so its electromagnetic field follows the drive’s sinusoidal currents with minimal slip. Its encoder supports multi-turn position measurement across 4096 revolutions, allowing the inductive sensor to retain absolute position information across power cycles. The smooth shaft is suited to clamping couplings that transfer torque through frictional contact. Because the motor is self-cooled, sufficient clearance around the housing is necessary to maintain unrestricted airflow during continuous operation.
