8LSA86.E1020D100-0 by B & R Automation

The 8LSA86.E1020D100-0 is a three-phase synchronous motor manufactured by B&R Automation within the 8LS Synchronous Motors series. It functions as a rotary drive for industrial automation equipment, supplying commanded torque and stable velocity to positioning tables, gantries, and other servo-controlled axes. The internal designation 8LSA denotes a standard configuration that omits bearing reinforcement, making the motor suitable for general-purpose duty cycles encountered in packaging, printing, and material-handling lines. Its synchronous design supports accurate speed control and repeatable motion when it is paired with a compatible servo drive.

This model delivers a rated speed of 2000 rpm, which sets the nominal operating speed for the motor under rated conditions. Heat is removed through self-cooling with free air circulation, eliminating the need for external blowers or liquid jackets. Rotor position is captured by an EnDat 2.1 optical encoder, allowing precise feedback to the servo amplifier during speed and position control. The mounting interface follows an IEC flange dimension of 240 mm, which suits machine layouts built for that flange size. Power is transferred through a shaft end supplied with a key, so torque can be passed to pulleys or couplings without slipping during acceleration and braking.

The feedback chain provides a resolution of 13/12 bits for single-turn and multi-turn tracking, while absolute position across multiple revolutions is maintained up to 4096 revs so position data remains available after power loss. Electrical and signal conductors exit through an angled connector that can swivel, helping cable routing in confined enclosures. The motor has no holding brake, so static load retention must be handled by the drive or by external mechanical means. The unit also has no oil seal, which makes it better suited to installations where shaft-area contamination control is handled by the surrounding machine.
