8LSA75.E2030D000-0 by B & R Automation

B&R Automation manufactures the 8LSA75.E2030D000-0 as part of the 8LS Synchronous Motors series. This rotary servo unit drives machine axes in industrial automation where accurate speed regulation and repeatable positioning are required. It converts three-phase electrical power into controlled mechanical rotation, allowing equipment such as pick-and-place heads, conveyors, and format adjustment modules to follow precise motion profiles from the drive controller. This makes it suitable for applications where an axis must accelerate, decelerate, and hold a commanded path through repeated production cycles.

The motor uses a square flange that measures 190 mm on each side, providing a standardized mounting face for equipment frames. During operation, the rotor can maintain a rated speed of 3000 rpm, which supports command frequencies used in packaging and material-processing lines. All cabling exits through an angled swivel housing, so the connector block can be oriented to relieve strain without changing the motor position. Power and feedback conductors are combined in a single industrial connector, which reduces wiring complexity and helps keep the installation compact. Heat is removed by self-cooling through free circulation, so the housing relies on ambient airflow instead of an external fan or liquid circuit. The square flange also helps align the motor consistently on prepared mounting plates.

The internal designation is 8LSA, indicating the standard motor configuration used for this model. The standard configuration does not include reinforced bearings. Attachment to the machine is made through the integrated mounting flange, and the output side uses a smooth shaft for clamp hubs or timing-belt pulleys. Because the shaft has no keyway, torque transfer depends on a clamping element matched to the application. The motor has no holding brake, so position locking must be handled by the drive or an external clamp. No oil seal is fitted, which limits use in areas exposed to pressurized coolant. As a three-phase synchronous motor, it runs without rotor slip.
