8LSA55.DB030S000-3 by B & R Automation

The 8LSA55.DB030S000-3 is a three-phase synchronous motor from B & R Automation and belongs to the 8LS Synchronous Motors series. It functions as a servo axis drive element in automated machinery. The motor supplies precise torque and speed control when connected to the manufacturer's integrated motion platform. This design supports coordinated motion on equipment that depends on repeatable acceleration, steady running speed, and accurate positioning through repeated cycles.

This model follows the 8LSA standard configuration without reinforced bearings and uses length code 5, so it is intended for applications that do not require upgraded bearing support. A mounting flange with a face dimension of 142 mm lets the motor attach directly to machine frames, and a smooth shaft end supports straightforward coupling alignment. Rated operation reaches 3000 rpm, which suits packaging, pick-and-place, and indexing tasks that need fast and consistent motion. Power, feedback, and brake leads are combined in a single-cable solution that terminates in a sealed connector, which helps reduce wiring complexity around the axis. Cooling uses the self-cooling principle, so no external blower is required. Because the motor has no oil seal and no holding brake, external sealing or static holding must be provided when the application requires it.

Position feedback is supplied by an inductive EnDat sensor that uses the EnDat 2.2 protocol and provides a resolution of 19/12 bits for single-turn and multi-turn position values. The encoder supports up to 4096 multi-turn revolutions, which allows homing-free positioning over longer motion cycles and helps the drive retain position information across repeated travel sequences. Internal data structures use Product revision 3 for compatibility with current B & R servo inverters. The connection direction is fixed to a hybrid cable, so cable routing must follow that orientation during installation. Because the motor lacks an oil seal, the installation area must stay within the permitted contamination limits.
