8LSA35.E3030D000-0 by B & R Automation

The 8LSA35.E3030D000-0 belongs to the 8LS Synchronous Motors series produced by B&R Automation. Classified under the 8LSA designation, it is intended for positioning and velocity control on packaging lines, pick-and-place gantries, and other motion axes that require accurate electrical commutation instead of mechanical gearing. In operation, it responds to servo drive commands with controlled rotation for indexing, transfer, and coordinated axis movement in automated equipment. This layout suits automated stations where repeatable starts, stops, synchronized speed changes, and accurate following of controller commands are more important than fixed-speed operation from line power alone.

The motor reaches a rated speed of 3000 rpm, giving the drive a common operating point for many servo applications. Its flange measures 91.3 mm, so the housing can mount to standard metric frames while keeping the stator length within the size-5 footprint associated with length code 5. Heat is removed through self-cooling by free circulation, which eliminates external fans and simplifies airflow around the machine. Power and feedback leave the housing through a sealed connector, supporting quick cable removal when the motor must be disconnected. A smooth shaft transmits torque to couplings or pulleys without a keyway, which helps avoid local stress concentration at high speed. The outlet position keeps cables close to the motor body and helps routing in tight enclosures.

The standard configuration uses standard bearings, so radial loads must remain within the permitted range for the motor. Mechanical fixation is handled by a mounting flange that aligns the stator face to the machine plate and sets axial position tolerance. Because the motor uses a three-phase synchronous design, torque delivery remains smooth and helps reduce velocity ripple on precision axes. There is no holding brake, and the oil seal is also omitted, which reduces inertia and friction during rapid direction changes. The cable outlet uses an angled swivel connection, providing strain relief and keeping the bend radius consistent during repetitive motion cycles.
