8LSA74.E0030D000-0 by B & R Automation

The 8LSA74.E0030D000-0 is a three-phase servo motor produced by B&R Automation within the 8LS Synchronous Motors series. As a drive component for industrial automation, it converts electrical power into controlled mechanical rotation for positioning or speed-regulated tasks. This unit follows the 8LSA configuration, which indicates a standard housing without a reinforced bearing, and it uses a smooth shaft for direct coupling to the load. That layout suits machine designs that need precise rotary motion without added shaft features or auxiliary mechanical elements.

The stator is wound for a nominal operating point of 3000 rpm, making it suitable for applications that need consistent mid-range speed. Its electromagnetic layout is that of a three-phase synchronous machine, so rotor position remains locked to the supplied frequency during operation. Rotor feedback is delivered by an optical EnDat encoder that uses protocol version 2.1; this combination provides position data with a single-turn and multi-turn resolution of 13/0 bits. Length code 4 indicates the fourth stator stack size in the family. Electrical connection is made through a swivel angled connector, and the detachable connector shell carries the power and signal conductors at the motor interface.

Mechanical integration is handled by a mounting flange with a face dimension of 190 mm. Heat generated in the windings is removed by a self-cooling design that relies on free air circulation, eliminating the need for external blowers or liquid circuits. The cable exit uses an angled swivel orientation so harnesses can be routed parallel to the machine frame. The motor has no holding brake, so static load locking must be provided by a separate brake or gear stage when required. Additional details include the absence of an oil seal, the use of standard connector hardware, and flange-mount construction only.
