Product Description:
The 8LSA43.R0030D100-0 is a three-phase synchronous motor produced by B&R Automation as part of the 8LS Synchronous Motors series. Designed for servo axes in packaging, material-handling, and general motion systems, it converts drive current into rotational torque that can be precisely regulated by a closed-loop controller. The model carries the 8LSA designation, indicating a standard build without reinforced bearings, and its compact form allows direct integration into machines that require rapid positioning with repeatable accuracy.
With a rated speed of 3000 rpm, the rotor can follow high-frequency command profiles while remaining within the magnetic and thermal limits of the stator. Position feedback is supplied by a resolver, an analog transducer that produces sine-cosine signals for shaft angle measurement. A 100 mm flange provides the square mounting interface and bolt pattern for connection to gearboxes or machine frames. Heat generated in the windings is removed through self-cooling that relies on free air circulation, eliminating the need for external fans or liquid circuits. Mechanical repeatability is specified at 10 arcmin, supporting applications that require tight positioning tolerance. This feedback arrangement allows the connected servo drive to monitor rotor position and regulate motion throughout each operating cycle.
The power and feedback leads exit through an angled connection that can swivel, simplifying cable routing in confined installation spaces and on moving axes. Electrical terminations are made with a sealed connector, and the unit attaches directly to the machine through its flange without requiring additional mounting brackets. The motor has no holding brake, so static load retention must be supplied by drive torque or an external mechanical device. Torque is transmitted through a keyed shaft, providing positive engagement with a compatible coupling or driven component. The shaft does not have an oil seal and is intended for operation in clean environments where exposure to lubricants and contaminants is limited. The motor has length code 3, which indicates the stack depth associated with the torque capability of this frame.
