Product Description:

The 8LSA44.DA030S200-3 synchronous motor is produced by B&R Automation as part of the 8LS Synchronous Motors series. It is a three-phase synchronous unit that provides closed-loop torque and speed for automated pick-and-place stages, conveyors, and other motion axes. Its synchronous design allows the paired drive to regulate rotor position accurately during acceleration, steady running, and stopping. The internal designation 8LSA indicates a standard construction without reinforced bearings, which suits machinery that does not place high radial loads on the shaft.

Mechanical attachment uses a mounting flange with a span of 100 mm, which matches common servo gearboxes and machine frames. The rotor uses length code 4 to balance inertia and continuous torque, and a single-cable hybrid solution carries power and encoder data through one plug-style connector. This arrangement reduces separate cable runs between the motor and the drive. Thermal management relies on self-cooling with free circulation, so no external blower or liquid circuit is required. For power-off safety, the motor includes a standard holding brake, and nominal output is delivered at 3000 rpm. The lack of an oil seal limits installation to dry areas, and product revision 3 identifies the current motor version.

Position feedback is supplied by an Inductive EnDat encoder that uses version 2.2. The system provides 19/0 bits of single-turn and multi-turn information, giving high-resolution position data within one mechanical revolution and transferring that data digitally to the servo amplifier. Because the multi-turn value is zero, position information resets on power-up, which suits machines that complete a homing routine at startup. The motor has a smooth shaft interface, which permits backlash-free coupling with clamped hubs or shrink discs where keyways are not required.
