Product Description:
The 8LSA54.R0045D000-0 is a rotary motor manufactured by B&R Automation and supplied within the 8LS Synchronous Motors series. Intended for servo axes on packaging lines, pick-and-place arms, or material-transport stages, the device converts controlled AC power from a drive inverter into precise mechanical rotation. By integrating with an electronic drive, it serves as the actuator in a closed-loop motion system, delivering repeatable speed and position so automated equipment can maintain production tolerances and cycle times.
This model uses a mounting flange measuring 142 mm across, providing a footprint compatible with common gearbox adapters. Length code 4 indicates a rotor-stator stack designed for mid-range torque without excessive inertia. Operating as a three-phase synchronous motor, it reaches a rated speed of 4500 rpm for rapid indexing duties. Heat is removed through self-cooling with free circulation, eliminating the need for external fans or separate liquid-cooling equipment. Power and feedback cables leave the stator through an angled swivel connector, which supports flexible cable routing and strain relief. The motor uses standard bearings without reinforcement and does not include an oil seal, making it suitable for clean, enclosed applications where the shaft is not exposed to lubricants or process fluids.
Rotor position is monitored by a resolver, an analog feedback device that resists electrical noise and high temperatures. Its feedback signal supports a system precision of 10 arcmin at the mounting flange, allowing the drive to regulate angular position during controlled motion. Because the motor is supplied without a holding brake, vertical or overhung loads must be secured by drive-applied torque or an external clamp when power is removed. A smooth shaft simplifies attachment to collets or clamping sleeves and avoids the localized stress associated with a keyway at high rotational speeds. The mounting flange centers the housing against the machine interface to support accurate alignment, while the circular connector allows the power and feedback cables to be disconnected without opening the motor housing.
