8LSA26.R0060D000-0 by B & R Automation

The 8LSA26.R0060D000-0 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. Within the type code, the 8LSA designation indicates a standard build without a reinforced bearing, and length code 6 identifies the active stack height. In industrial automation, the unit converts drive current into precisely timed rotary motion for indexing tables, packaging spindles, and other high-speed axes where compact dimensions and repeatable positioning are required. Its synchronous design supports accurate speed control when it is operated from a compatible servo drive. This makes it suitable for applications that need fast response during repeated start-stop motion and stable rotation at elevated speed.

Power and feedback conductors leave the housing through an angled swivel interface, reducing cable bend radius in tight enclosures. A flange face of 58 mm supports direct coupling to gear stages while preserving a small footprint. The rotor is rated for continuous operation at 6000 rpm, enabling quick acceleration and deceleration cycles without exceeding standard servo speed limits. Heat is removed by self-cooling through free air circulation, so no fan or liquid circuit is needed. Position and velocity are returned to the drive by a resolver, which tolerates electrical noise and high shock better than optical encoders. Because no oil seal is installed, shaft surface speed and ambient cleanliness must be considered during application use. The cable outlet can also be turned to ease routing around nearby machine frames and guarding.

A smooth shaft eases the press fit of couplings or pulleys and avoids keyway stress concentrations. The internal alignment of stator and rotor is held to 10 arcmin, providing adequate precision for general-purpose servo loops. Fixing is carried out through the integral mounting flange, so no foot plate is necessary. The motor ships without a holding brake, making external locking devices necessary where power-off position retention is critical. The standard bearing set supports general machine duty, and the design is best suited to clean, dry production zones. The flange-mounted format also helps keep the motor body compact for direct machine integration.
