Product Description:
The 8LSA43.R0045D000-0 is a rotary motor produced by B&R Automation within the 8LS Synchronous Motors series. As a compact servo unit, it couples directly to machine axes and uses electromagnetic torque to position loads in industrial automation lines, material-handling stations, and packaging cells. The design code places it in the 8LSA configuration family, indicating a standard mechanical build without reinforced bearings. A mounting flange lets the motor bolt to rigid frames, and the absence of an oil seal makes it suitable for dry rooms or cabinet installations where protection from fluids is unnecessary.
The motor is optimized for production speeds up to 4500 rpm, allowing motion controllers to execute rapid indexing or continuous-duty cycles without exceeding thermal limits. A square flange measuring 100 mm across provides a stable interface for gearheads or belt pulleys. Heat is removed through self-cooling with free air circulation, so no external fan or liquid loop is required. Airflow over the aluminum stator housing helps maintain the winding temperature during operation. Rotor position feedback comes from a resolver, which tolerates vibration and electrical noise while providing rotor angle information to the servo amplifier. Power and feedback cables exit the housing through an angled swivel connector that can be rotated during installation to relieve strain. The internal tolerance stack limits cumulative backlash to 10 arcmin, supporting pick-and-place or vision-guided operations that require repeatable positioning.
The output journal has a smooth shaft, so torque is transmitted by clamp couplings rather than keyways when assembling drives with low shaft-to-hub play. The motor is supplied without a holding brake, which reduces inertial load and suits applications where the drive amplifier provides static torque or an external clamp secures the axis at rest. Applications with suspended or vertical loads must use an appropriate external holding method when power is removed. The electromagnetic core uses a three-phase synchronous topology. Balanced sinusoidal currents energize the stator and synchronize the permanent-magnet rotor with the commanded electrical angle, providing accurate motion and high torque during operation.
