8LSA45.E2030D100-0 by B & R Automation

The 8LSA45.E2030D100-0 is a rotary actuator built by B&R Automation for the 8LS Synchronous Motors series. As a servo-class unit, it converts drive current into synchronized torque for positioning and speed control in automated machinery. The motor installs on the standard 8LSA mechanical platform, allowing direct flange mounting on gearboxes or machine frames while the drive handles current, velocity, and feedback control. This layout makes the unit suitable for compact motion systems where accurate shaft response and straightforward mechanical integration are required.

The motor uses a Three-phase synchronous winding, which supports stable torque production during controlled operation. Under nominal supply, the rotor reaches 3000 rpm, making it suitable for conveyors, pick-and-place axes, and other mid-speed duties. Heat is removed through a self-cooling design that relies on free air circulation, so no external blower or liquid circuit is required. Motor cabling exits through an angled swivel connection, which helps routing in tight spaces and reduces strain on the integral plug. The mounting face uses a 100 mm flange, providing the centering diameter and bolt pattern commonly needed for direct machine attachment.

The motor has no holding brake, so vertical load retention must be provided by the drive or by an external brake when power is removed. Electrical and feedback lines connect through a sealed connector, allowing connection without re-terminating leads. The build uses length code 5, which corresponds to the rotor stack used for this torque class. The motor has no reinforced bearing, which suits applications that do not place unusually high radial loads on the shaft. It mounts by flange, and because no oil seal is fitted, the installation area should remain free of pressurized lubricant spray and similar contamination.
