8LSA35.E2030D100-0 by B & R Automation

The 8LSA35.E2030D100-0 is a three-phase synchronous motor produced by B & R Automation and supplied within the 8LS Synchronous Motors series. This standard version, delivered without a reinforced bearing, balances mass and dynamic response for medium-inertia loads. In automated production lines, the motor converts bus-fed AC power into controlled rotation, allowing indexing tables, gantries, or conveyor sections to follow commanded speed and position profiles with minimal settling time. That operating role suits machines that need repeatable starts, stops, and controlled motion during cyclic production.

Its nominal operating point is 3000 rpm, providing a predictable mechanical frequency that simplifies gear ratio selection and feedback scaling. The flange face spans 91.3 mm, so the housing seats precisely against standard IEC-compatible machine frames. The motor uses self-cooling through free circulation, eliminating external blowers and helping preserve performance where available cabinet airflow is limited. Power and feedback conductors exit through an angled connection, reducing cable bend stress when the motor is mounted close to moving axes or guarding. A pluggable connector allows the harness to be removed without opening terminal boxes.

The stator uses a mounting flange that aligns the shaft to couplings or pulleys without additional brackets. The output journal is machined with a key, so torque is transferred through a positive drive element rather than friction alone. Overall length follows length code 5, which gives this frame a stack height suited to its torque constant while keeping inertia moderate. The internal 8LSA configuration does not include an oil seal or holding brake, so those functions can be provided elsewhere if the application requires them. This arrangement keeps the motor simple for installations that rely on external sealing or separate static holding methods during standstill.
