Product Description:

The 8LSA44.R2030D100-3 synchronous servo motor is produced by B&R Automation for the 8LS Synchronous Motors series. This three-phase machine converts drive current from a matched inverter into rotational motion that positions or transports loads inside automated production equipment. It is intended for controlled motion tasks such as indexing, conveying, and general axis positioning where stable speed response and repeatable movement are required.

The motor reaches a rated speed of 3000 rpm, providing nominal velocity for packaging axes that need steady throughput. The 8LSA housing mates to machinery through a square flange measuring 100 mm, so alignment with gearboxes or belt pulleys follows a common industrial pattern. Rotor position feedback is delivered by a resolver, letting the drive compute vector current even when electrical noise is present. Electrical terminations exit on an angled swivel outlet, so the cable can be routed downward with less strain near the connection point. Maximum backlash at the keyed shaft connection is limited to 6 arcmin. Length code 4 indicates the active stack height, and the 8LSA designation indicates a standard bearing set without reinforcement. A keyed shaft end secures torque transfer, and the three-phase synchronous winding supports constant torque across the working speed range.

Thermal management uses self-cooling with free circulation, so the unit sheds heat through its aluminum frame instead of forced air or liquid jackets. Installation is by a mounting flange, which keeps the motor aligned with the machine interface and leaves clearance for the cable outlet. The motor has no holding brake, so external clamping or drive torque is required to hold position when power is removed. Power and feedback lines mate to one connector, which keeps external wiring consolidated at a single interface. The standard bearing layout is intended for applications that do not require reinforced bearings.
