Product Description:
The 8LSC5B.E0030D100-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. Within that series, it carries the internal designation 8LSC, indicating the standard mechanical layout used for this platform. The unit serves as a compact drive source for positioning axes and speed-controlled conveyor stations where electronically commutated torque and precise encoder feedback are needed for coordinated motion in industrial automation. Its synchronous design supports responsive speed regulation when the motor is paired with a compatible drive controller.
This motor reaches a rated speed of 3000 rpm and removes internal heat through a built-in fan assembly, allowing continuous operation without external cooling ducts. A flange face measuring 142 mm provides the primary mounting surface and aligns the motor with the machine frame through the supplied mounting flange. Its B length code indicates the axial stack used to achieve the listed torque class. Feedback is generated by an optical EnDat encoder that operates with EnDat version 2.1, providing fully digital position data to the drive controller. Power and signal leads exit through an angled swivel connection, and a single mating connector simplifies cable routing around the motor. Product revision 3 identifies the electronics and winding revision used for this model.
The encoder offers a resolution of 13/0 bits for single-turn and multi-turn position data, making it suitable for point-to-point axes that do not require multi-turn position storage. Output torque is delivered through a shaft with a keyway, enabling positive mechanical engagement with couplings or pulleys. The motor uses a standard configuration without a reinforced bearing, which helps limit rotational inertia when operating with moderate radial loads. It is supplied without a holding brake, so static position retention must be handled by the drive or an external clamp. The motor also has no oil seal and is intended for installations where the surrounding machine enclosure controls exposure to oil and other contaminants. Appropriate external guarding can protect the shaft interface when the motor operates near processing fluids or airborne debris.
