Product Description:

The 8LSA55.R2030D100-3 servo motor is manufactured by B&R Automation as part of the 8LS Synchronous Motors series. Classified under the internal 8LSA designation, it follows the standard build that omits reinforced bearings, making it suitable for a wide range of general motion axes. Within an automation cell, the motor converts electrical power into controlled rotary motion for indexing tables, pick-and-place units, and other position-critical devices. A keyed shaft end and a flange mounting surface allow direct coupling to mechanical loads, while a resolver inside the housing provides real-time rotor position feedback to the drive.

The unit reaches a rated speed of 3000 rpm, providing a balance between torque and cycle time. Thermal energy is dissipated through self-cooling by free circulation, so no external blower or liquid circuit is required. Power and feedback leads exit through an angled swivel connector arrangement that eases cable routing in tight cabinets, and the mating interface is a standard industrial connector. Mechanical integration relies on a square mounting face with a 142 mm flange dimension, matching many gearbox and frame standards. Internally, Product Revision 3 and Length Code 5 identify the present stack length and recent design update.

As a three-phase synchronous design, the motor develops constant torque over the entire speed range and accepts sinusoidal current from a matched inverter. The built-in resolver supports positioning accuracy of 6 arcmin, which meets requirements for packaging and machining lines. Installation is done with a rigid mounting flange, and torque is transmitted through the shaft end furnished with a key to help prevent slip under load. Because no holding brake is installed and an oil seal is not present, external restraints or sealing elements are required when stop-state torque retention or fluid exclusion is necessary. The standard bearing configuration further emphasizes applications where radial impacts remain within normal service limits.
