8LSA43.E3030D000-0 by B & R Automation

The 8LSA43.E3030D000-0 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. Carrying the internal designation 8LSA, the unit is intended for precise position and speed control on servo axes used in packaging machines, pick-and-place gantries, and other automated stations that require repeatable motion profiles. This motor is suited to applications that need stable closed-loop motion and consistent response during indexing or synchronized travel. Its overall body size follows length code 3, which keeps the housing compact enough for installations with limited axis space.

The motor reaches a rated speed of 3000 rpm, allowing direct coupling to gearless transmissions in medium-inertia loads. Heat is removed through a self-cooling with free circulation design, eliminating the need for external fans or liquid circuits. A square flange measuring 100 mm on each side sets the mounting pattern and mates to standardized machine frames. Power and feedback cables exit the housing through an angled swivel interface so conductors can be routed along linear guides without sharp bends, and termination is handled with a screened connector. This layout supports compact cable routing where moving axes require controlled bend paths and reliable shielding continuity.

The A-type configuration uses a standard bearing set, so no reinforced bearing option is fitted, and the assembly ships without a holding brake, so static torque must be provided by the drive when power is removed. It is also supplied without an oil seal, which suits clean, dry environments where lubricant migration is not expected. Mechanical attachment relies on the integrated mounting flange, while the smooth shaft supports backlash-free clamp couplings and avoids the stress concentration associated with a keyed journal. The lack of reinforced bearings also helps keep rotating inertia low for rapid dynamic response.
