Product Description:
The 8LSA43.R2030D000-3 is manufactured by B & R Automation as part of the 8LS Synchronous Motors series. This unit belongs to the vendor’s 8LSA product line and functions as a drive motor that converts electrical energy into rotary motion for positioning tables, gantries, and packaging axes in industrial automation cells. By combining compact frame dimensions with servo-grade accuracy, the device supplies constant torque at commanded speeds so controllers can move loads without mechanical gear reduction. Its synchronous operation supports precise speed and position control when the motor is paired with a compatible servo drive.
The machine uses a three-phase synchronous design, so its stator windings are energized by balanced three-phase power for high power density and straightforward vector control. It has a rated speed of 3000 rpm, which is the upper continuous operating velocity before field weakening is needed. The front face has a 100 mm flange pattern that aligns with compatible IEC gearboxes, and the shaft maintains repeatable indexing within 6 arcmin. Rotor position is reported by a resolver, allowing the drive to calculate the electrical angle during acceleration. Length code 3 indicates the magnetic stack depth, while product revision 3 identifies the current design revision. The standard 8LSA configuration does not include a reinforced bearing, which helps keep rotor inertia low for responsive motion.
Thermal management relies on self-cooling through free air circulation, eliminating the need for external fans or liquid jackets when the motor is mounted on a machine frame. Power and feedback leads exit through angled swivel connectors, providing cable relief where installation space is limited. The shaft interface is a smooth shaft, making it suitable for clamp couplings when concentric alignment is required. Installation uses a mounting flange for secure attachment to the machine or a compatible gearbox. The motor does not have a holding brake for static retention, so a mechanical lock may be required on a vertical axis when power is removed. An oil seal is not included, so the shaft area should not be exposed to splash zones that require sealed protection against lubricants or other fluids.
