Product Description:

The 8LSA56.EA045D000-1 belongs to the 8LS Synchronous Motors series manufactured by B & R Automation. This rotary servo motor converts controlled three-phase current from a drive controller into regulated torque and speed for positioning or velocity-controlled axes in automated machinery. It is intended for closed-loop motion tasks where the drive manages acceleration, speed, and position during repeated machine cycles.

The motor uses a three-phase synchronous electromagnetic topology and reaches a rated speed of 4500 rpm, allowing fast indexing cycles. A flange dimension of 142 mm establishes the mounting footprint, and length code 6 indicates the motor's stack length. The mechanical interface is a smooth shaft, which is suited for clamp-style or shrink-fit couplings; because no shaft oil seal is fitted, external sealing is required if the shaft passes through a pressurized chamber. Power and feedback conductors are routed through an angled swivel connector orientation that simplifies cable routing in tight cabinets. The motor uses flange mounting, and it is supplied without a holding brake, so static load retention must be handled by the drive or by external mechanics.

Position feedback relies on an Inductive EnDat system with single-turn reporting, complemented by 19/0-bit encoder resolution for fine incremental control. Communication follows protocol version 2.1, which supports automatic calibration and digital temperature monitoring by the drive. Heat is removed by self-cooling through free circulation, eliminating the need for forced airflow or liquid jackets. The connection hardware uses a standard circular connector that mates directly with B & R hybrid cables, which helps keep wiring compatible with the motor's intended cable system.
