Product Description:

The 8LSA26.E4045D000-0 synchronous servo motor is produced by B&R Automation and belongs to the 8LS Synchronous Motors series. It uses a three-phase synchronous design and carries the 8LSA designation, which indicates a standard configuration without a reinforced bearing. Designed for flange mounting, the unit drives axis positioning and speed control in industrial automation where compact, high-speed rotary motion is required. Its operating role suits machines that need repeatable movement with closed-loop feedback rather than simple constant-speed rotation.

With a length code of 6, the stator package uses an extended active iron stack to support continuous torque in high-duty applications. The motor reaches a rated speed of 4500 rpm, supported by self-cooling with free air circulation that removes heat without external blowers. A square interface of 58 mm across the flange helps align the motor on compatible machine faces, and a sealed connector reduces direct exposure of power and feedback wiring. Position information is generated by an optical EnDat encoder that provides 13/0 resolution data for closed-loop operation. This feedback arrangement supports accurate speed regulation and stable position monitoring during repeated motion cycles.

The connection exits the housing in an angled swivel orientation, which helps cable routing in confined spaces. The motor uses a smooth shaft end for clamp or friction-based couplings, and it is supplied without a holding brake, so static holding must come from the drive or an external device. Feedback communication follows EnDat version 2.1, allowing deterministic serial data exchange between the motor and the control system. Because no oil seal is fitted, the motor is better suited for installations where surrounding fluids are limited and the shaft area remains clean during operation.
