Product Description:
The 8LSA55.E3045D000-0 is a rotary motor manufactured by B&R Automation for the 8LS Synchronous Motors series. The device integrates with compatible servo drives to deliver controlled torque and speed in automated packaging lines, handling equipment, and assembly stations. As part of the 8LSA configuration, it is intended for installations where a compact envelope and standard bearing set are suitable. Its synchronous operation supports accurate motion profiles during repeated acceleration, positioning, and deceleration cycles.
Rated for 4500 rpm, the motor is suitable for medium-speed indexing or spindle applications that require fast cycle times. Its three-phase synchronous architecture keeps rotor movement synchronized with the stator field, allowing the drive to command torque with precise electrical phasing. Heat generated during operation is removed by self-cooling through free air circulation, so no external fan or liquid cooling jacket is required. Installation is guided by a flange face that measures 142 mm, providing a consistent mounting interface for frame alignment. Power and feedback leads exit through an angled swivel connection, helping reduce cable strain when the motor is mounted near moving joints or within confined machinery. The adjustable connection direction also allows cables to be routed away from nearby couplings and structural components.
The standard 8LSA build uses a bearing without reinforcement, making it appropriate for standard couplings rather than applications with heavy radial loads. The magnetic stack has a length code of 5, providing the active iron volume needed for the motor’s torque characteristics. The unit attaches to machinery through an integrated mounting flange, eliminating the need for foot brackets and supporting concentric alignment with a gearbox or machine plate. Output torque is transmitted through a smooth shaft, which is suitable for clamping couplings that do not require a keyway. The motor is supplied without a holding brake, so an external mechanism or drive-applied torque must secure the load when the axis is stationary. It also has no oil seal, so the installation must prevent lubricants and contaminants from reaching the shaft opening. A keyed circular connector provides a secure connection for the motor’s power and feedback wiring without requiring access to an internal terminal box.
