8LSA43.R2030D000-3 by B & R Automation

The 8LSA43.R2030D000-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. This model serves as a drive element in automated axes that require constant torque at a commanded frequency. The 8LSA configuration uses the standard bearing arrangement rather than a reinforced bearing, and the smooth shaft end couples directly to gearboxes or belt pulleys. It is suited to positioning and speed-controlled tasks in packaging, assembly, and transfer equipment where coordinated axis motion is required. The motor mounts by a square flange and uses resolver feedback so it can operate in coordinated motion systems with a servo drive.

The motor reaches a nominal speed of 3000 rpm, allowing closed-loop controllers to achieve moderate linear velocities without overspeeding the mechanics. As a three-phase synchronous motor, the rotor moves in step with the stator field, which helps maintain stable speed regulation. Heat is removed by self-cooling through free circulation, so no external blower is required. Power and feedback lines exit through an angled swivel connector, which helps reduce cable strain in compact machines. The 100 mm flange dimension fits matching machine plates and keeps the motor centered during installation.

Positioning accuracy is maintained within 6 arcmin, supporting applications that require repeatable tool or load placement. Rotor position is reported by a resolver, allowing the drive to close current and velocity loops even under vibration. The motor uses a mounting flange as its sole fixation method, which keeps mechanical integration straightforward. It does not include a holding brake, so any axis that must remain locked with power removed needs an external clamp. Additional details include connector-based wiring hardware, length code 3 for the stack size, revision 3, and an omitted oil seal that is better suited to dry environments.
