Product Description:
The 8LSA55.db030s500-3 servo motor is produced by B&R Automation and belongs to the 8LS Synchronous Motors series. It serves as a compact drive element that converts electrical power into rotational motion for positioning axes, conveyors, and packaging spindles in automated machinery. Integrated feedback and standardized mechanical interfaces allow the unit to be paired with compatible B&R drives, enabling motion commands from a PLC to produce accurate shaft movement. This arrangement supports closed-loop control of motor position, speed, and torque as operating conditions change.
The motor uses a three-phase synchronous operating principle, enabling sinusoidal stator excitation that balances torque production across all three phases. Its rated shaft speed of 3000 rpm establishes the nominal operating point for load calculations when the motor is coupled to a gearbox or direct drive. A flange diameter of 142 mm provides a consistent centering surface, making alignment with precision gear reducers straightforward. Heat is removed through self-cooling with free air circulation, so no external fan or liquid-cooling jacket is necessary. This cooling method requires adequate open space around the housing so naturally circulating air can carry heat away from the motor. Power and signal conductors terminate in a single connector, which provides a compact connection point and helps keep cable routing orderly within the machine.
Machine integration is handled through a mounting flange, which provides a fixed reference plane and a uniform bolt pattern for secure attachment. The mechanical stack depth uses length code 5, allowing the required space behind the mounting face to be considered when adjacent components are positioned. The product is issued as Revision 3, supporting compatibility with the corresponding B&R servo drives and parameter files. It is supplied in an 8LSA standard configuration without a reinforced bearing. This bearing arrangement is intended for moderate radial loads commonly produced by belt drives or light gear couplings, while applications with greater shaft loading may require additional external support.
