8LSA44.EB030D000-3 by B & R Automation

The 8LSA44.EB030D000-3 is a three-phase synchronous motor produced by B & R Automation as part of the 8LS Synchronous Motors series. Classified under the 8LSA designation, it serves as a standard rotary actuator without reinforced bearings for positioning, conveying, or spindle tasks in automated machinery. Length code 4 sets the overall housing depth, and the smooth shaft end simplifies coupling to clamping hubs.

This model runs at a rated speed of 3000 rpm, enabling direct coupling to transmission elements without additional gearing for many medium-speed axes. Heat is removed through self-cooling through free circulation, so no external blower or liquid circuit is required. Power and feedback lines exit through an angled swivel arrangement that helps route cables parallel to moving machine parts, and the interface uses a sealed connector. Mechanical integration is handled by a 100 mm mounting flange, with the flange edge size identified as 100 mm; this matches common IEC motor plates and aligns precisely with the machine frame. The configuration is a standard 8LSA version without reinforced bearings, and the lack of an oil seal limits the motor to clean environments where coolant or lubricant ingress is unlikely.

Position feedback is provided by an Inductive EnDat encoder that uses the 2.1 protocol, giving a resolution of 19/12 bits in single-turn and multi-turn modes. Multi-turn capability extends to 4096 revs, allowing absolute position retention across long linear strokes without homing. Because the motor has no holding brake, external clamping devices must secure vertical loads when power is removed. The mounting flange is pre-drilled, and the motor is product revision 3. The internal 8LSA designation remains consistent across the product line, and the connector hardware supports an electrically pluggable design.
