Product Description:

The 8LSA55.R0030D100-0 synchronous servo motor is produced by B&R Automation for the 8LS Synchronous Motors series. Supplied in the 8LSA standard configuration without reinforced bearings, the unit serves as a compact drive element for positioning axes in automated assembly lines and packaging equipment. It combines three-phase stator technology with permanent-magnet excitation to deliver responsive torque under closed-loop servo control. The housing is proportioned for tight spaces, enabling accurate rotational motion to synchronize conveyors, pick-and-place arms, or feed rollers in compact machinery.

Built as a three-phase synchronous motor, the 8LSA55.R0030D100-0 reaches a rated speed of 3000 rpm, allowing servo drives to coordinate fast indexing cycles with stable speed control. A flange dimension of 142 mm provides a stable mounting face that matches common IEC layouts, while length code 5 keeps the body short for dense installations. Cooling relies on self-cooling through free air circulation, which removes the need for external blowers. Power and feedback conductors exit via an angled swivel connector, so wiring can be routed parallel to the machine frame and strain can be relieved at the connector.

Position feedback is handled by a resolver, which supplies rotor angle data in electrically noisy environments. This sensor supports a mechanical accuracy of 10 arcmin, which is adequate for packaging seal wheels, winding stations, and other axes that do not require sub-arcminute precision. Because there is no holding brake, the axis must rely on drive torque or an external clamp to maintain position during power-off states when vertical loads are absent. Torque is delivered through a keyed shaft, enabling straightforward coupling to gearheads or belt drives while maintaining concentricity with adjoining machinery.
