Product Description:

The 8LSA56.S1045D200-1 is a three-phase synchronous servo motor produced by B&R Automation as part of the 8LS Synchronous Motors series. It converts commanded current from a drive into controlled torque and speed for positioning axes and continuous-duty transport tasks on automated machinery. With integrated encoder feedback and a mounting flange, the motor supports closed-loop motion control and straightforward installation in packaging equipment, material handling stations, and other industrial systems. Its synchronous design also supports repeatable motion where stable speed and accurate positioning are required over long operating cycles.

The motor has a rated speed of 4500 rpm, and it delivers motion through a smooth shaft that couples directly to the load. A flange diameter of 142 mm matches the mounting face commonly used on mid-frame gearboxes and is paired with the standard bearing arrangement for this version. Electrical and signal conductors leave the housing through an angled swivel connection with a sealed connector, which helps route cables in compact machine spaces. Cooling is provided by self-cooling with free air circulation, so no external blower or liquid jacket is required, and position feedback is supplied by an optical EnDat encoder for high-resolution commutation and absolute position tracking.

The feedback system uses EnDat version 2.2 communication and a 25/12-bit single-turn and multi-turn resolution to provide precise absolute position data. Its multi-turn counter retains indexing for up to 4096 revs, which helps the axis return to a known position after a power interruption without an additional reference run. The shaft is secured by a standard holding brake when control power is removed, and the motor has length code 6 for its housing depth. Because no oil seal is present, the front bearing should be protected from process fluids in washdown environments.
