Product Description:
The 8LSA86.E0020D100-0 is a servo motor produced by B&R Automation for the 8LS Synchronous Motors series. Designed for closed-loop positioning and speed control in industrial automation, this unit supplies precise torque to conveyors, pick-and-place axes, and similar machine modules when paired with a compatible drive controller. The motor converts regulated electrical power into controlled rotary motion while its feedback system reports shaft position to the drive. This arrangement allows the controller to correct speed and position errors as operating loads change. The 8LSA baseline configuration provides a conventional industrial form factor for integration into automated machinery.
The motor is a three-phase synchronous unit, allowing it to lock rotor speed to the drive’s output frequency while maintaining smooth torque delivery. Its nominal shaft speed is 2000 rpm, making it suitable for applications that operate within a moderate velocity range. Heat is removed through self-cooling with free air circulation, eliminating the need for an external fan. Power and feedback conductors exit through an angled swivel connector, simplifying cable routing where installation space is limited. The mounting flange measures 240 mm across and provides a stable reference surface for alignment with the machine frame. Length code 6 indicates the active stack height used in this motor configuration. The standard build does not include a reinforced bearing, so applied radial and axial loads must remain within the limits of the standard bearing arrangement. An oil seal is not installed at the shaft opening.
Position feedback is supplied by an optical EnDat encoder that transmits digital position information to the controller. The communication protocol uses version 2.1 to support fast and accurate feedback exchange during controlled motion. The encoder provides 13-bit resolution in single-turn mode, allowing the drive to distinguish fine angular increments within one shaft revolution. It does not store multi-turn position data, so the system may require a reference procedure when absolute position across multiple revolutions is needed after power is restored. Torque is transmitted through a shaft end with a key, providing positive engagement with compatible couplings, pulleys, or gears. The motor does not include a holding brake. External mechanical restraint or drive-applied torque must secure stationary loads when power is removed.
