8LSA34.R0030D000-0 by B & R Automation

The 8LSA34.R0030D000-0 synchronous servo motor is produced by B&R Automation and belongs to the 8LS Synchronous Motors series. It is a three-phase synchronous unit intended to drive coordinated axes and position loops in general industrial automation. Within the series, the 8LSA designation indicates the standard configuration without reinforced bearings, and the motor is supplied in length code 4. Paired with a mounting flange, the motor integrates easily into compact machinery where accurate speed and torque regulation are required.

Its mechanical interface starts with a flange that measures 91.3 mm across, allowing the motor to align with common gearheads and couplings. Power and feedback cables exit through an angled swivel connector, reducing strain in tight control cabinets, and the connection hardware is a sealed industrial connector rated for repeated mating cycles. Position feedback is provided by a resolver, which supplies rotor position information for closed-loop control without requiring a digital encoder. Thermal management relies on self-cooling with free circulation, so no external fan or coolant piping is needed. Under nominal load, the rotor reaches a rated speed of 3000 rpm, making it suitable for packaging, pick-and-place, and indexing axes.

This length-4 variant uses a stator package identified as 4, which balances torque density against cabinet depth. Motion accuracy at the output shaft is held within 10 arcmin, a value suitable for material-handling gantries that do not require sub-arcminute alignment. Because the shaft is a smooth shaft, custom couplings or pulleys can be mounted without keyway limitations, and the motor is supplied without an oil seal, so the installation must remain free of pressurized lubrication. The motor ships with no holding brake, so vertical axes require external mechanical locking when power is removed.
