Product Description:
The 8LSA46.DB030S300-3 is a synchronous servo motor built by B&R Automation for the 8LS Synchronous Motors series. As a compact rotary actuator, it supplies controlled torque and speed to automated stations that need coordinated motion, such as pick-and-place heads or indexing tables. The model follows the 8LSA configuration and uses a standard bearing arrangement without reinforcement. It attaches to machinery through a mounting flange, allowing accurate shaft alignment during assembly.
The drive section uses a three-phase synchronous design, allowing sinusoidal current from a matched inverter to energize its permanent-magnet rotor with minimal torque ripple. Nominal output is reached at a rated speed of 3000 rpm, which is suitable for midrange positioning tasks that balance dynamic response and mechanical service life. The square front face has a flange dimension of 100 mm, providing a consistent mounting interface for gearboxes or couplings. Position feedback is generated by an inductive EnDat encoder that has low sensitivity to dust and temperature drift. Its resolution is 19/12 bits in single-turn and multi-turn modes, supporting precise electronic commutation and absolute position retention after power cycles.
A standard holding brake is integrated to prevent shaft rotation when power is removed, which helps secure vertical loads and supports emergency stopping. Thermal management relies on self-cooling with free circulation, so no external fan or coolant loop is required and heat dissipates through the aluminum housing. Power, feedback, and brake conductors leave the stator through a single-cable hybrid solution, simplifying cable routing and reducing panel terminations. Communication with the controller uses EnDat version 2.2, enabling advanced diagnostic communication between the motor and controller. The motor has a keyed shaft end for positive torque transfer and does not include an oil seal, making it appropriate for clean applications where the shaft is not exposed to lubricant. Length code 6 identifies the active stack length, while product revision 3 indicates the motor’s release generation.
