Product Description:

B&R Automation's 8LSA43.R2030D100-3 is a three-phase synchronous motor in the 8LS Synchronous Motors series. The unit serves as an electromechanical actuator in automated machinery, converting drive-controller commands into continuous rotary motion for indexing tables, gantry axes, and conveying modules. It carries the internal designation 8LSA, length code 3, and product revision 3, which indicate its physical stack height and electrical winding. The configuration is standard and does not include a reinforced bearing, so it is intended for applications that do not impose extreme radial or axial loads.

The motor reaches a rated speed of 3000 rpm, enabling direct coupling to medium-speed transmission stages without overspeeding. It has a flange dimension of 100 mm, which supports interchange with other IEC-sized frames. Power and feedback conductors exit through an angled swivel connector, a layout that simplifies cable routing in tight cabinets. Position sensing relies on a resolver, which provides analog sine-cosine signals for closed-loop control in electrically noisy environments. Thermal limits are managed by self-cooling with free circulation, so ambient airflow removes losses without auxiliary fans or liquid circuits.

The motor uses a mounting flange for standardized face mounting and accurate centering during installation. The shaft is machined with a key, providing positive torque transfer to pulleys or couplings. Static positioning accuracy is held to 6 arcmin, which supports moderate repeatability in indexing and positioning tasks. The motor has no holding brake, so an external brake is required for vertical axes or other loads that must remain fixed when power is removed. An oil seal is also absent, which makes this version better suited to applications that do not require added sealing for pressurized washdown areas.
