Product Description:

The 8LSA44.EB022D000-3 is a three-phase synchronous motor produced by B & R Automation for the 8LS Synchronous Motors series. It carries the 8LSA designation, ships as product revision 3, and uses length code 4 to indicate the stack depth of its active core. Built for servo axes in automated assembly, packaging, and handling machines, the motor transforms drive output into precise rotary motion while reporting absolute rotor position through an onboard inductive encoder. The absence of an internal holding brake makes it suitable for systems that lock the load externally during power-down events.

At a rated speed of 2200 rpm, the motor sustains continuous operation without exceeding its thermal limits. The square mounting interface measures 100 mm across the flange, giving it a direct fit with standardized machine frames. Position data are produced by an inductive EnDat sensor that communicates with the drive using protocol version 2.1. This interface delivers an absolute resolution of 19/12 bits for single-turn and multi-turn measurement, supporting tight speed and position loops. Power and feedback lines terminate at a detachable connector, and the stator winding is configured for balanced three-phase excitation.

Thermal management relies on self-cooling through free air circulation, so no external blower or liquid circuit is required. The cabling exits through an angled swivel connector that can be rotated to align with the routing path and limit bending stress. Output torque is transmitted through a smooth shaft. Because an oil seal is not present, the surrounding gearbox or coupling must provide the necessary barrier against contaminants. Encoder memory retains position over power cycles through its multi-turn capability of 4096 revolutions, allowing the feedback system to restore the recorded position without requiring a homing move after startup.
