Product Description:

The 8LSA34.E3030D200-0 is a three-phase servo motor built by B&R Automation for the 8LS Synchronous Motors series. It uses the 8LSA configuration, so it is supplied in standard form without reinforced bearings. As a rotary actuator for industrial automation, the unit converts drive current into controlled mechanical torque and speed so that machine axes can follow motion commands with precision. In typical use, it serves as the motion source for compact machine axes that require accurate starts, stops, and speed changes.

Electrically, the motor is a three-phase synchronous design, allowing sinusoidal commutation and tight velocity regulation. Its rated speed is 3000 rpm, which is the shaft velocity it can maintain continuously under nominal load. Thermal management relies on self-cooling through free air circulation, so the housing dissipates heat directly into ambient air without external blowers or liquid jackets. This arrangement keeps the motor package simpler and avoids the added hardware associated with separate cooling systems. Power and feedback conductors exit the stator through an angled swivel arrangement, and the mating interface uses a sealed connector for quick cable changes and flexible routing.

Mechanical attachment uses a flange with a pilot diameter of 91.3 mm, aligning to a standard mounting flange pattern on gearboxes or machine frames. A standard holding brake is integrated to secure the load whenever the drive is disabled, helping prevent uncommanded motion on vertical or indexing axes. The keyless shaft end uses a smooth shaft style, which simplifies coupling to clamped hubs and helps minimize backlash. This shaft arrangement also supports direct connection to components that rely on friction-locking hubs rather than keyed interfaces. Because no oil seal is present, the motor should be installed in environments where external contamination is already controlled.
