8LSA34.R2030D000-3 by B & R Automation

B&R Automation builds the 8LSA34.R2030D000-3 for its 8LS Synchronous Motors series. The unit is a compact three-phase synchronous motor intended to drive positioning or feed axes inside automated machinery. Belonging to the 8LSA configuration, it carries the standard bearing set without reinforcement and relies on a flange interface for straightforward insertion into mechanical frames. The absence of an internal brake makes it suitable for systems where the holding function is provided by the drive amplifier or an external clamp.

The motor reaches a rated speed of 3000 rpm, giving cyclic equipment enough velocity while remaining within the thermal limits of the winding. Rotor position feedback is supplied by a resolver, so the associated controller receives absolute angle information even during power-up. A square mounting surface with a flange dimension of 91.3 mm sets the bolt circle and eases interchange with similar IEC sizes. Heat is removed through self-cooling with free air circulation, so the machine builder does not need forced ventilation, but free airflow around the housing is required. Power and signal lines exit through an angled swivel connector, allowing cable runs to be oriented parallel to the machine bed and minimizing strain during routing.

The output end is a smooth shaft, so couplings must rely on friction clamping rather than keys. Repeatable bidirectional motion is maintained within 6 arcmin of mechanical backlash, supporting moderate positioning accuracy without external gear compensation. A rigid mounting flange transfers torque directly into the host frame, and the overall build follows revision 3 of the product design, which aligns with the current B&R cable and resolver pinout standard. Length code 4 sets the active stack height, the connector hardware is pre-installed for quick hookup, and no oil seal is fitted at the nose because the motor is intended for clean, dry environments.
