Product Description:

The 8LSA44.DB030S300-3 servo motor is manufactured by B & R Automation and belongs to the 8LS Synchronous Motors series. Designed for industrial automation, it converts electrical energy into controlled rotary motion for positioning, conveying, and general machine axes. It is suited for servo systems that require repeatable speed regulation and accurate position control during continuous machine cycles. Integration of power, feedback, and brake circuits inside one compact housing allows direct placement on tooling stations while reducing cabinet wiring.

The unit follows the 8LSA configuration, which uses a standard rotor without reinforced bearings and length code 4 for its active magnetic stack. At rated load, the shaft turns at 3000 rpm and is built for three-phase synchronous operation. Electrical connection uses a hybrid single-cable connection that ends in a molded connector, so power, brake supply, and digital feedback share one shielded line. Position data come from an Inductive EnDat encoder that communicates via EnDat 2.2 and provides 19-bit single-turn plus 12-bit multi-turn resolution. A square mounting flange measuring 100 mm provides the locating surface, and the keyed shaft supports direct coupling to gearboxes. The motor is built as revision 3.

Thermal management relies on self-cooling through free air circulation, eliminating external fans for typical duty cycles. A standard holding brake integrated at the rear secures the load whenever the drive is disabled and receives its power through the hybrid lead. The absolute encoder tracks up to 4096 revs across power interruptions, so the controller retains position without a homing cycle after restart. Because the shaft has no oil seal, it should not be exposed to pressurized coolant.
