Product Description:

The 8LSN56.EA030D000-0 is a three-phase synchronous servomotor manufactured by B&R Automation for the 8LS Synchronous Motors series. Within the 8LSN designation, this model uses length code 6 and includes a mounting flange for secure installation. It is intended for precise motion axes in industrial automation, where controlled torque, speed, and position are required for packaging lines, pick-and-place modules, and similar equipment.

This standard-configuration motor achieves a rated speed of 3000 rpm, allowing it to support consistent cycle times in high-speed motion applications. The mounting interface uses a 142 mm flange, which permits rigid attachment to compatible gearboxes or machine frames. Power and feedback conductors exit through an angled swivel connector that helps reduce cable bend stress and supports flexible routing within the available installation space. Thermal management relies on self-cooling, so the motor dissipates operating heat without an external fan. The increased rotor inertia helps damp speed fluctuations during load changes and can provide smoother operation in applications with less aggressive acceleration requirements. Because the motor does not have an oil seal, the shaft area must remain protected from lubricants, coolants, and other process fluids that could reach the internal components.

For feedback, the motor integrates an inductive EnDat encoder that uses protocol version 2.1 to transmit absolute position information to the servo drive. The encoder has a 19/0-bit resolution, providing 19-bit position data within one mechanical revolution without multi-turn position tracking. This single-turn arrangement suits indexing, positioning, and electronic camming applications that do not require the encoder to retain the number of completed shaft revolutions. Mechanical power is transmitted through a smooth shaft, allowing the use of a suitable clamping coupling for a secure connection to the driven equipment. The motor is supplied without a holding brake, so vertical or otherwise gravity-loaded axes require drive-applied torque or an external mechanical restraint when stationary. Its electromagnetic design supports linear torque production across the operating range while limiting cogging that could otherwise affect motion smoothness at low speeds.
