8LSA55.R2030D000-3 by B & R Automation

The 8LSA55.R2030D000-3 is a three-phase synchronous motor engineered by B & R Automation within the 8LS Synchronous Motors series. In the model code, 8LSA indicates a standard configuration without a reinforced bearing, making the unit suitable for general-purpose positioning and velocity control in packaging axes, gantries, material transfer stations, and similar automated machinery. The three-phase synchronous design supports closed-loop operation where the drive must maintain accurate speed and position during repeated motion cycles. Supplied without a holding brake or oil seal, the motor mounts by its flange and is intended for applications that do not require integrated load holding or additional shaft sealing.

The motor attains a rated speed of 3000 rpm, enabling high cycle rates on equipment that demands rapid acceleration and steady servo response. That operating speed suits machinery with short indexing times and frequent start-stop movement. Heat is removed through self-cooling by free air circulation, eliminating the need for external fans or liquid loops and simplifying installation in enclosed machine spaces. Power and feedback leave the housing through an angled swivel outlet that terminates in a connector, easing cable routing in confined control cabinets and tight machine frames. The motor uses a 142 mm flange with a smooth shaft for direct coupling to standardized machine interfaces and backlash-free couplings.

Motion feedback relies on a resolver, and internal repeatability is specified at 6 arcmin, which supports moderate accuracy requirements in indexing conveyors, transfer units, and pick-and-place heads. Resolver feedback provides rotor position data across the operating range for common servo control tasks. The active stack length code 5 balances continuous torque and overall motor length for installations that need compact dimensions without giving up servo performance. Product revision 3 indicates the current mechanical and electrical release used for this version. The motor uses standard bearings for applications where axial load and contamination are controlled.
