Product Description:
The 8LSA46.EA045D000-0 is a synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. In automated machinery, it serves as a rotary actuator that converts electrical power into controlled mechanical motion. The motor is suitable for axes that require repeatable speed and position control in packaging equipment, handling systems, and other industrial machines. Its standard 8LSA configuration supports self-contained installation within the machine assembly.
The unit has a three-phase synchronous design that uses permanent-magnet excitation to keep the rotor synchronized with the drive frequency. It operates at a rated speed of 4500 rpm, supporting applications that require rapid and accurately regulated movement. Heat is removed through self-cooling with free air circulation, eliminating the need for an external blower when sufficient airflow is available. Position feedback is supplied by an Inductive EnDat encoder that supports EnDat 2.1 digital, bidirectional communication with the drive. Its single-turn capability provides the angular position within one mechanical revolution, allowing the control system to monitor rotor movement accurately. The motor has a flange diameter of 100 mm, providing an aligned mounting interface for compatible gearboxes and machine frames.
Power and signal cabling exits through an angled swivel connector, which allows the cable direction to be adjusted in confined installation spaces. The sealed connector provides removable terminations instead of fixed pigtails and helps protect the electrical contacts from surrounding contaminants. Encoder resolution is 19/0 bits for single-turn and multi-turn position data, respectively, providing fine angular granularity within one revolution without recording completed revolutions. The motor has no holding brake and no oil seal, so an external mechanism or drive-produced torque must retain stationary loads, and the shaft area must be kept away from lubricant exposure. Length index code 6 indicates a medium magnetic stack that provides a balance between rotor inertia and power density. The smooth shaft end accepts clamp-style or friction couplings for transferring torque without a keyway. The standard bearing arrangement is not reinforced and is intended to carry normal radial loads within the motor’s permitted operating range.
