8LSA34.R0030B000-0 by B & R Automation

The 8LSA34.R0030B000-0 is a compact servo actuator produced by B & R Automation within the 8LS Synchronous Motors series. Classified as a three-phase synchronous motor, it converts drive current directly into rotary motion for positioning axes, conveyor segments, and tooling spindles in automated machinery. Its compact housing suits equipment that needs a servo motor close to moving mechanisms without using excessive installation space. The 8LSA type code indicates the standard build without reinforced bearings for general industrial duty.

During operation, the unit reaches a rated speed of 3000 rpm, allowing rapid cycle completion while staying inside typical servo loop bandwidths. A flange face diameter of 91.3 mm sets the mounting envelope and mates with standard gearboxes or frames. Power and feedback cabling exits the housing at a 270° rightward angle so cable loops remain clear of moving parts. This routing can help keep the cable path orderly when the motor is installed beside slides or rotary tables. Rotor position is reported by an integrated resolver, enabling closed-loop control in electrically noisy zones and giving the drive continuous angle information. Heat generated by copper losses is removed through self-cooling with free air circulation, eliminating the need for external blowers. Under these conditions, the mechanical backlash error stays within 10 arcmin, supporting mid-level precision tasks such as indexing tables and pick-and-place heads.

Drive power is routed through a connector mounted on the stator end cap, which keeps electrical connection points compact at the motor housing. The rotor uses a smooth shaft, favoring clamp or hub couplings and avoiding keyway stress risers. Because there is no holding brake, static loads must be secured by the drive or an external lock when power is removed. The mounting flange follows length code 4 dimensions, and the oil seal is omitted, so the motor should be installed in dry zones or paired with an external shaft seal when fluids are present. This layout is suitable for applications where the machine already provides the needed load holding and sealing at the driven end.
