8LSA44.DB060S300-3
B & R Automation produces the 8LSA44.DB060S300-3 as part of the 8LS Synchronous Motors series. It is a three-phase synchronous motor built for flange mounting so that it can deliver precise rotary motion in automated packaging, material-handling, and light machining axes. The 8LSA designation indicates a standard configuration without reinforced bearings, while the keyed shaft simplifies mechanical coupling to belts, gears, or direct drives in compact assemblies.
The motor’s maximum working velocity reaches 6000 rpm, a rating that supports fast indexing cycles when paired with compatible B & R servo inverters. A flange that measures 100 mm across fits directly to standardized machine plates, keeping alignment repeatable and limiting the need for additional adapters. Feedback comes from an Inductive EnDat system that communicates over EnDat 2.2, giving absolute position data with high noise immunity. Heat is dissipated by self-cooling through free circulation, so no external fan or liquid circuit is required; this lowers maintenance needs and permits installation inside sealed electrical cabinets.
Cabling is simplified through a single-cable solution that carries both power and encoder signals in one hybrid connector, reducing wiring points and drag-chain weight. A standard holding brake secures the shaft whenever the drive is disabled, preventing load drift on vertical or suspended axes. The encoder provides 19/12-bit resolution for single-turn and multi-turn data, and it supports multi-turn tracking up to 4096 revolutions without losing count after power loss. The motor has no oil seal, so the shaft passage should be protected from fluid ingress if the motor is placed in lubricated environments; this detail should be considered alongside the length code 4 build and product revision 3 for new or retrofit machinery.
