Product Description:

The 8LSA55.S0030D900-3 synchronous motor is produced by B & R Automation as part of the 8LS Synchronous Motors series. Carrying the 8LSA designation, it is supplied as a standard unit without reinforced bearings and is used to drive precision axes in automated assembly cells, material-handling stations, and packaging equipment where constant velocity and accurate positioning are required. When paired with a suitable inverter, the motor converts commanded electrical input into controlled rotary motion for repeatable axis movement. Its configuration is suited to servo-driven machinery that requires accurate starts, stops, and speed changes over repeated production cycles.

Mechanically, the motor follows length code 5 and bolts to machinery through a mounting flange that has a 142 mm register, and the shaft end is equipped with a key for positive torque transfer. Cooling is handled by self-cooling through free circulation of ambient air, so no external blower or liquid circuit is needed. Electrically, the unit is a three-phase synchronous machine with a rated speed of 3000 rpm, enabling stable speed when supplied by a matched inverter. Position feedback is provided by an Optical EnDat encoder that delivers 25 bits of single-turn resolution and no multi-turn data. The feedback and power leads exit through an angled swivel connection, and fixed connector hardware helps keep cable routing orderly in compact machine spaces. An oil seal protects the interior against lubricant ingress, and the motor is revision 3.

The motor has a standard holding brake, which clamps the rotor when supply power is removed and helps hold the shaft at standstill. The feedback channel uses EnDat 2.2 protocol, allowing drive electronics to access position data and diagnostic information while recognizing the encoder’s single-turn format. All power, brake, and signal conductors are routed through a swivel connector, and the angled exit direction helps maintain cable clearance in tight installations. This layout supports compact mounting spaces where nearby guards, panels, or machine framing limit straight cable runs.
