8LSA43.R0022D100-0 by B & R Automation

The 8LSA43.R0022D100-0 is a servo motor manufactured by B & R Automation for the 8LS Synchronous Motors series. The 8LSA configuration denotes a standard build that omits reinforced bearings and suits general-purpose motion axes. Paired with a compatible drive, the unit converts commanded currents into controlled rotation, enabling precise positioning in packaging lines, pick-and-place modules, and conveyor systems. Its compact form factor allows installation in tight electrical enclosures without dedicated cooling ducts.

Its nominal operating speed is 2200 rpm, allowing the motor to deliver rated torque continuously at that speed. The square four-bolt interface uses a 100 mm flange dimension, aligning the stator housing with gearboxes or direct-drive frames that share this bolt circle. Position error is limited to 10 arcmin, enabling tight registration for printing or indexing duties. Thermal energy exits the housing by self-cooling, using free air circulation instead of forced fans or liquid jackets, so installation does not require auxiliary chillers. Rotor feedback is provided by a resolver, giving analog sine-cosine signals that remain readable during shock or temperature excursions. Additional characteristics include connector-style power terminals, a length code 3 stator stack, and no integrated holding brake or oil seal.

The stator windings form a three-phase synchronous system, allowing the drive to apply vector control for smooth torque across the speed range. Mechanical attachment uses a mounting flange, simplifying alignment within compact machine frames. The shaft end is supplied with a key, giving a positive lock to couplings or pulleys. Cabling exits the housing through an angled swivel connector so harnesses can be routed parallel to the motor body and away from moving links.
