Product Description:
The 8LSA46.EB030D100-3 is a synchronous servo motor produced by B&R Automation within the 8LS Synchronous Motors series. This standard 8LSA configuration is engineered for positioning and velocity control tasks that require accurate rotary motion. Suitable applications include packaging equipment, assembly systems, and material-handling axes in industrial automation.
The unit uses a three-phase synchronous motor design, allowing balanced torque generation from a three-phase supply while simplifying drive selection. Its nominal shaft speed reaches 3000 rpm, providing the operating speed required for a range of controlled motion tasks. A square mounting interface with a 100 mm flange aligns the housing with machinery that follows compatible IEC frame patterns. Position feedback is handled by an inductive EnDat encoder that operates with the EnDat 2.1 protocol and delivers absolute position information to the drive without batteries. The encoder transmits 19/12 bits of resolution for single-turn and multi-turn position data, providing fine angular granularity for interpolated motion profiles and repeatable axis control.
Thermal management relies on self-cooling through free air circulation, so ambient airflow around the housing dissipates heat without auxiliary fans or liquid circuits. The motor has no holding brake, so vertical axes or applications that require load retention must use an external braking device. Its output interface consists of a shaft with a key, providing positive torque transmission to pulleys, gearboxes, or rigid couplings. The integrated encoder supports multi-turn counting across 4096 revolutions, allowing absolute position tracking over multiple shaft rotations and position recovery after power is restored. Connection wiring exits the stator through an angled swivel connector, which allows the cable direction to be adjusted for the available installation space. The motor attaches to a machine plate through its mounting flange, and its shaft arrangement does not include an oil seal.
