Product Description:

The 8LSA26.R0006D000-3 is a compact synchronous servo motor built by B&R Automation within the 8LS Synchronous Motors series. As a three-phase motor, it converts electrical power into precise rotary motion for indexing tables, packaging lines, and other closed-loop automation axes. The unit serves as a controlled torque source that can be coupled directly to gearboxes or load shafts, allowing accurate motion without belts or hydraulic transmission. Its compact format suits machines where installation space is limited and direct-drive response is important.

Electrically, the motor uses a three-phase synchronous design, so stator excitation and rotor position remain coordinated for stable speed control. Thermal management relies on self-cooling with free circulation, so no external fan or liquid circuit is required. Position feedback is provided by an integrated resolver, allowing the controller to monitor rotor position during operation. The stator face has a 58 mm flange that mates with IEC size-58 gearboxes. Power and feedback lines exit through an angled swivel connector assembly, which helps reduce cable strain in tight spaces. The motor has no holding brake, so standstill torque must be supplied by the drive or by external mechanical restraint.

Mechanically, the rotor uses a smooth shaft, which supports backlash-free clamp or keyless hub connections. Positional repeatability is maintained within 10 arcmin, making the motor suitable for pick-and-place heads and other axes that need moderate accuracy. The front face includes a mounting flange, and the shaft area has no oil seal, so it should be kept away from pressurized fluids or heavy contamination. It is supplied in a standard configuration without reinforced bearing, which keeps inertia low but reduces radial load capacity for belt-driven arrangements. If an application applies higher side loads, external bearing support should be used at the driven element.
