8LSA37.R2030D000-3 by B & R Automation

The 8LSA37.R2030D000-3 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. It is delivered in the 8LSA standard configuration, which means that no reinforced bearing or auxiliary oil seal is fitted. Used as a drive element in industrial automation, the unit converts controlled three-phase power from a servo inverter into precise rotary motion for packaging axes, material transfer stations, and small machining spindles. The mounting flange permits direct integration with planetary gearboxes or machine frames where a compact footprint is required.

The motor supports a rated speed of 3000 rpm, enabling high cycle rates without the need for mechanical speed increasers. Thermal management relies on self-cooling with free circulation, so airflow around the housing is enough to keep the winding within limits under rated load. Cabling exits through an angled swivel connector interface, allowing leads to be routed toward the cabinet while relieving strain. Rotor position is tracked by an internal resolver that withstands shock and elevated temperatures common in servo zones. Mechanical attachment follows a DIN-style 91.3 mm square flange, which simplifies interchange with other IEC motors.

Closed-loop accuracy is held to 6 arcmin, which meets positioning requirements for indexing tables and pick-and-place heads. The electromagnetic design uses a three-phase synchronous layout, so torque remains linear with current and no slip is introduced. For applications that already provide static holding torque through external means, the motor arrives without a holding brake to minimize mass and inertia. A smooth shaft eases the use of clamp or shrink-disc couplings. Length code 7 indicates the stator stack height, and product revision 3 matches the winding set used with current B&R drives.
