Product Description:
The 8LSA26R0045D100-0 is an AC servo motor built by B&R Automation within the 8LS Synchronous Motors series. It converts drive inverter output into controlled rotary motion for positioning duties in automated handling, packaging, and assembly stations. By delivering precise speed and angle commands directly to the load, the unit can reduce the need for mechanical belts and gear reductions. This arrangement also helps maintain repeatable process sequences within modern production cells. The synchronous motor design provides responsive motion when paired with a compatible servo drive and control system.
Its electrical and feedback lines terminate in a connector, so cabling can be attached or removed without rewiring fixed terminal strips. Heat generated during operation is dissipated through the housing by a self-cooling principle that relies on free air circulation. This cooling method eliminates auxiliary fans and reduces the number of moving components requiring maintenance. The motor face has a flange dimension of 58 mm, providing a consistent mechanical interface for aligning the shaft with gearheads or load couplings. The mechanical stack depth uses length code 6, which indicates a longer stator section than those associated with shorter length codes. The additional stator length accommodates a greater active winding length and supports higher continuous output than smaller frame lengths.
The electromagnetic configuration is three-phase synchronous, which allows the permanent-magnet rotor field to remain synchronized with the stator’s rotating magnetic field. This operating principle supports accurate speed tracking under inverter control and provides predictable torque response during acceleration, steady motion, and deceleration. The frame includes a rigid mounting flange, so the motor can be fastened directly to a compatible machine plate without separate foot or face adapters. Front-side mounting also supports direct shaft alignment with a coupling or gearbox during installation. The 8LSA designation identifies the A variant of the motor family and indicates the associated housing shape and electrical interface. Units that share this letter code use the corresponding physical arrangement for integration with compatible cables, drives, and mounting components.
