8LSA35.R0022D100-0 by B & R Automation

The 8LSA35.R0022D100-0 synchronous motor is produced by B&R Automation within the 8LS Synchronous Motors series. It is a three-phase synchronous unit intended to generate controlled torque and velocity for positioning axes, conveyors, and packaging machinery. The internal designation 8LSA identifies the standard build type, while length code 5 indicates the active stack size selected for medium power ranges. Using this motor allows a servo drive to match rotary loads without external gear reduction, which improves responsiveness in automated assemblies.

The motor reaches a rated speed of 2200 rpm, allowing servo control to remain stable up to that limit. Its square mounting interface uses a flange dimension of 91.3 mm, which aligns with IEC-compatible gearheads and machine frames. Position feedback is handled by a resolver, providing analog sine and cosine signals that remain usable at high ambient temperatures and in electrically noisy environments. Power and sensor leads exit through an angled swivel connector arrangement, which helps reduce cable strain in compact installations. The connector hardware allows connection without soldering or terminal screws.

The housing uses self-cooling with free circulation, so ambient airflow removes heat losses without external fans or liquid loops. Mechanical accuracy is supported by a precision rating of 10 arcmin, which is suitable for moderate indexing duties on printing or pick-and-place stations. The shaft end is machined with a key for torque transmission to pulleys or couplings, and the front face includes a mounting flange for attachment to the machine frame. The motor uses a standard bearing without reinforcement, which is adequate for belt or light gear loads. No holding brake or oil seal is installed, so position retention and environmental sealing must be handled at the application level.
