8LSA44.DB060S300-3 by B & R Automation

The 8LSA44.DB060S300-3 is a three-phase synchronous motor manufactured by B & R Automation within the 8LS Synchronous Motors series. As part of an electrically commutated servo system, it supplies tightly regulated torque and speed for automated packaging, material-handling, and assembly axes that rely on rapid positioning accuracy. In operation, it converts electrical commands from the drive into controlled rotary motion for coordinated axis movement. The motor is intended for applications that need rapid acceleration, controlled deceleration, and accurate stop positioning during repeated production cycles.

A rated output speed of 6000 rpm sets the upper continuous operating range and suits high-throughput machinery. Mechanical coupling uses a flange with a diameter of 100 mm and a shaft end with an integral key for positive torque transmission. The flange-mounted format also supports direct installation on machine plates or gearbox faces. Thermal energy leaves the housing through self-cooling with free air circulation, so no forced ventilation is required. Power and feedback are carried through a single-cable hybrid connection, which keeps cabling compact between the motor and drive. Rotor position is monitored by an inductive EnDat encoder that communicates with drives using EnDat 2.2 protocols. The 8LSA configuration indicates a standard build without reinforced bearings, and length code 4 identifies the stator stack size.

The encoder provides a resolution of 19/12 bits for single-turn and multi-turn tracking, and it stores absolute position across 4096 multi-turn revolutions so reference moves after power cycles are unnecessary. A standard holding brake is fitted to secure the load during shutdown or emergency-stop events. The product is identified as Revision 3. Connection hardware uses a removable industrial connector, and because the shaft has no oil seal, the installation area should be free of pressurized coolant or lubricant spray.
