Product Description:

The 8LSA46.E2045D000-0 is an AC servo motor manufactured by B&R Automation for the 8LS Synchronous Motors series. As a three-phase synchronous unit, it converts controlled inverter current into rotary motion for positioning, conveying, and machining axes in automated equipment. The "8LSA" designation within the part number identifies it as a standard configuration motor without a reinforced bearing, aligning with applications where moderate radial loads are expected. Its overall design follows IEC metric flange dimensions so that it can be paired directly with gearboxes or mechanical couplings on the production line.

At the core of the motor's performance envelope is a rated speed of 4500 rpm, which is the maximum continuous shaft velocity before field weakening becomes necessary. The rotor-stator system operates on a three-phase synchronous principle, so torque generation remains proportional to control current with minimal slip. A 100 mm flange provides a standardized mounting face and maintains concentricity between the housing and load. Electrical power and feedback conductors approach the stator through angled swivel connections terminated by a dedicated connector, an arrangement that shortens cable loops in tight enclosures. Heat from copper losses is removed through self-cooling airflow, so no external fan or liquid circuit is required for nominal duty.

The motor is supplied without a holding brake, which reduces inertia for rapid acceleration but requires an external axis lock when power is removed. A smooth shaft avoids keyway stress concentrations and is compatible with clamp or shrink couplings. Integration is simplified further by a built-in mounting flange and by the absence of an oil seal, a choice that lowers friction when the environment is clean. The internal stack identified by length code 6 indicates the active rotor length selected for the required torque.
