Product Description:

The 8LSA43.R0030D000-0 is a compact AC servo motor produced by B&R Automation within the 8LS Synchronous Motors series. It converts current from a compatible motion controller into rotary torque for positioning tables, pick-and-place axes, and other automated equipment. The motor supports controlled acceleration, speed regulation, and accurate positioning when paired with an appropriate servo drive. Its 8LSA configuration indicates a standard build without reinforced bearings, making it suitable for applications that do not impose unusually high radial loads. The low-maintenance design supports installation in automated machinery that requires precise and repeatable motion over extended operating periods.

This model operates at a rated speed of 3000 rpm, supporting fast indexing duties commonly found in packaging and electronic assembly lines. Its electromagnetic design uses a three-phase synchronous topology, providing predictable torque response and controlled operation across the intended speed range. A square flange measuring 100 mm provides a consistent reference surface for rigid attachment to a gearbox or machine frame. Power and feedback conductors pass through an angled swivel connector, which allows the cable exit direction to be adjusted when installation space is limited. Heat is removed through self-cooling by free-air circulation, allowing continuous operation without an external blower or liquid-cooling circuit. Adequate clearance around the housing helps natural airflow carry heat away from the motor during operation.

Rotor position feedback is generated by a resolver, which delivers analog sine-cosine signals that remain stable under vibration and elevated temperatures. The internal mechanical assembly provides a positioning accuracy of 10 arcmin, meeting moderate servo tolerances without requiring an additional encoder. A smooth shaft supports friction-lock hubs and clamping couplings while avoiding the stress concentrations associated with a keyway. Length code 3 indicates the magnetic stack depth used to balance torque capability with the overall housing length. The motor does not include a holding brake, so stationary loads must be retained by drive-applied torque or an external clamping device. It also lacks an oil seal and should therefore be installed in a dry area where the shaft interface is not exposed to lubricants or other liquids. A single multipole connector carries the required wiring, reducing the number of separate connection points on the housing.
