8LSA55.D0030D000-1 by B & R Automation

The 8LSA55.D0030D000-1 belongs to the 8LS Synchronous Motors series produced by B&R Automation. It is a brushless AC motor intended for position and velocity control on machine tool axes, packaging stations, and material-handling gantries. The motor follows the 8LSA configuration, which indicates a standard construction without reinforced bearings. It serves as a direct-coupled drive element that can reduce the number of gearboxes in modular automation layouts.

The stator is wound as a three-phase synchronous system, so torque is generated through continually commutated electromagnetic fields. A nominal speed of 3000 rpm matches drive regulators that use typical 400 Hz excitation, allowing rapid indexing while staying within thermal limits. Heat is removed by self-cooling with free air circulation, eliminating external blowers and simplifying enclosure layout. The square mounting face measures 142 mm, providing ISO-compatible bolt spacing for rigid attachment to machine frames. Position feedback is delivered by an optical EnDat encoder with protocol version 2.2, which supports simultaneous data transmission and electronic motor data transfer to the drive.

The encoder provides 25/0 bits of single-turn/multi-turn resolution, and this motor uses single-turn capability, which suits short-stroke axes where cumulative revolution tracking is unnecessary. Power and feedback leads exit through an angled swivel connection that reduces cable bend radius inside dynamic drag chains, and a sealed connector housing completes the interface. The housing uses flange mounting, and torque is delivered by a smooth shaft that mates to backlash-free clamp couplings. There is no holding brake or oil seal, so vertical loads must be restrained by external devices and the shaft area should be kept away from contaminated lubricants. This layout is better suited to clean, dry installations where the shaft end is not exposed to process fluids.
