8LSA34.E1030D100-0 by B & R Automation

The 8LSA34.E1030D100-0 is a three-phase synchronous motor produced by B&R Automation as part of the 8LS Synchronous Motors series. The 8LSA designation indicates a standard build without reinforced bearings, making the unit suitable for general-purpose motion systems. Integrated within automated machines, the motor supplies controlled torque and speed to linear or rotary actuators, supporting precise positioning tasks on packaging, assembly, and handling equipment. Its mounting flange simplifies installation, while the keyed shaft provides direct mechanical coupling to pulleys or gearheads. This standard configuration is appropriate for applications that do not require reinforced bearing support for unusually high mechanical loads. It also fits compact axis layouts where predictable servo response is more important than specialized mechanical options.

The motor reaches a rated speed of 3000 rpm, aligning with common servo drive outputs for moderate-inertia loads. Thermal management relies on self-cooling with free air circulation, so no external fan or liquid loop is required as long as ambient airflow is available. The motor has a flange diameter of 91.3 mm, which sets the mounting footprint and matches compatible couplings. Power and feedback conductors exit through an angled swivel connection, and the wiring uses a preinstalled connector that helps on tight machine panels. The swivel connection also helps route cables away from nearby guards, frames, and moving assemblies. The motor uses length code 4, which corresponds to a specific stack height and continuous torque range within the 8LS family.

Position feedback is provided by an optical EnDat encoder that communicates through the EnDat 2.1 protocol. The device captures shaft angle with 13 bits per revolution and retains 12 additional bits for revolution counting, giving a combined 13/12-bit resolution to the drive controller. Continuous tracking over power cycles extends to a multi-turn capability of 4096 revolutions, supporting homing-free machine startup. Because position is retained across multiple revolutions, the axis can resume controlled operation without an immediate reference run after power returns. The absence of a holding brake and oil seal reduces mass and keeps the motor layout simple, while the keyed shaft and swivel connector hardware fit standard couplings and cable sets used across the 8LS series.
