Product Description:
B&R Automation’s 8LSA37.SB030S000-3 is a three-phase synchronous servo motor in the 8LS Synchronous Motors series. The 8LSA designation indicates a standard configuration without reinforced bearings, making the unit suitable for general-purpose positioning in packaging lines, assembly cells, and material-handling systems. The motor converts electrical input from a compatible servo drive into controlled rotary motion for precise speed, torque, and position regulation. Its synchronous design supports repeatable movement during indexing, conveying, and other automated machine cycles.
The motor reaches a rated speed of 3000 rpm, supporting applications that require sustained high-speed operation. Its 91.3 mm flange dimension provides the mounting geometry needed for attachment to compatible gearheads or machine plates. Position feedback is supplied by an optical EnDat encoder that communicates through protocol version 2.2, allowing the drive to receive high-resolution absolute position data. A single-cable solution combines the power conductors and digital feedback cores in one shielded cable, reducing the number of separate connections required between the motor and drive. Electrical wiring terminates at a molded connector, which provides a compact and secure interface. This connection arrangement also reduces cable congestion around closely spaced machine axes.
The motor uses a self-cooling design that dissipates heat through natural air circulation without an external blower. The encoder provides a 19/12-bit resolution for detailed single-turn and multi-turn position data. Its multi-turn tracking range of 4096 revolutions allows absolute position information to remain available across repeated shaft rotations. The unit is produced as Revision 3, which indicates its internal component generation. Length code 7 identifies the active stack depth, while the smooth shaft supports installation with suitable clamping couplings. The mounting flange serves as the attachment surface for the motor housing. The motor is supplied without a holding brake, so stationary load retention must be provided by drive-applied torque or an external mechanism. It also has no oil seal, which reduces shaft friction and makes the motor better suited to clean operating areas where liquid contamination is not expected.
