Product Description:
The 8LSA56.S0045D200-1 is an AC servo motor produced by B&R Automation within the 8LS Synchronous Motors series. Designed to couple directly with the manufacturer’s AC drives, the unit converts electrical commands into repeatable mechanical rotation for indexing tables, packaging axes, and material-handling gantries. Its stator and rotor geometry permit high torque density, while the encoder channel provides absolute feedback for precise motion profiles in industrial automation cells. The motor also integrates with common IEC gearboxes, allowing it to serve applications that require compact and accurate rotary motion.
In its standard configuration, the motor is a three-phase synchronous machine, so it develops constant torque proportional to the current supplied by the drive. A nominal shaft speed of 4500 rpm establishes the gearing ratios needed to achieve the required cycle times. Heat is removed through self-cooling with free air circulation, and convection over the housing fins eliminates the need for a blower or liquid cooling circuit. A mounting face with a 142 mm flange provides direct attachment to gearboxes or machine frames without adapter plates. Power and feedback lines exit through an angled swivel connector, which permits cable routing to follow the machine envelope and reduces stress on the harness during axis movement.
A standard holding brake locks the shaft when the drive is disabled, preventing load drift on vertical or safety-critical axes. Position is measured by an optical EnDat encoder that operates with protocol revision 2.2, delivering bidirectional communication with the controller for calibration and diagnostic functions. The single-turn encoder provides 25/0 bits of resolution, with 25 bits for position within one mechanical revolution and no multi-turn position storage. The motor has a smooth shaft without an oil seal, a length code 6 stator stack, and compact connector hardware. The absence of multi-turn storage means the controller receives precise angular position within a single revolution without retaining the number of completed shaft revolutions.
