Product Description:

The 8LSA45.E2030D300-0 belongs to the 8LS Synchronous Motors series manufactured by B & R Automation. It is a motor unit intended for precision positioning and velocity control in automated machinery such as pick-and-place stations, feeders, and indexing tables. By delivering controlled torque directly to a mechanical axis, the device supports coordinated motion sequences that shorten cycle times and improve repeatability in industrial automation cells.

The drive section uses a three-phase synchronous design, so sinusoidal current from a matched inverter locks rotor speed to the stator field for accurate electronic commutation. Nominal operation occurs at 3000 rpm, a speed that balances high throughput with moderate bearing loads. Heat is removed through self-cooling with free circulation; the housing dissipates losses without external blowers or liquid loops, simplifying installation. Power and feedback conductors use an angled swivel orientation, which eases cable routing in narrow enclosures. The mating plug is a sealed industrial connector that provides a secure electrical connection.

An integral standard holding brake clamps the shaft when power is removed, preventing unwanted movement on vertical or overhung loads. The front interface follows a 100 mm square flange pattern that aligns with planetary gearboxes and adapter plates. Installation uses a rigid mounting flange that withstands torsional peaks during acceleration. Shaft torque is transmitted through a keyed end, and the motor has no oil seal, making it suitable for dry-coupled environments where lubricant migration is not expected. Length code 5 indicates the active stack depth, helping users evaluate inertia and continuous torque when pairing the unit with a servo drive that has the appropriate current capacity.
