8LSA55E2030d200-0 by B & R Automation

The 8LSA55E2030d200-0 is a three-phase servo motor manufactured by B&R Automation as a member of the 8LS Synchronous Motors series. In automated production lines, the unit converts drive current into precise rotational motion, allowing gantry axes, packaging mandrels, and pick-and-place heads to follow exact velocity and position commands. Its electromagnetic design delivers repeatable torque while maintaining phase alignment with the supplied sine-wave current, making it suitable for tasks that demand stable speed regulation and accurate indexing. The motor works with a servo drive to respond quickly to changing load conditions while keeping commanded motion smooth.

The motor uses a rear-mounted connector for power and feedback leads, so cabling can be replaced without disturbing the mechanical setup. Internal heat is removed through self-cooling by free air circulation, eliminating the need for external blowers or liquid loops and simplifying panel layouts. The motor has a three-phase synchronous design, so the rotor locks magnetically with the stator field and torque can be controlled directly through drive current. A square mounting interface of 142 mm sets the flange dimension and matches gearboxes or couplings in this size class. The stator stack with length code 5 increases active copper volume, providing higher continuous torque than shorter lengths in the same motor diameter.

In mechanical design, an integrated mounting flange lets the housing bolt directly to a frame or motor plate. The flange-based housing supports rigid alignment at the machine face, which helps maintain coupling accuracy during repeated start-stop cycles. The internal designation 8LSA marks the variant group used with this flange size, winding, and feedback options. Across the broader 8LS Synchronous Motors range, the same electromagnetic platform is used while motor length or winding changes alter torque output without changing the mounting points. Matching drive parameters support commutation, current limiting, and temperature monitoring during operation.
