Product Description:
The 8LSA36.R2045D000-3 is a three-phase servo motor produced by B&R Automation for the 8LS Synchronous Motors series. It is intended to drive machinery axes that require rapid positioning and consistent velocity regulation in industrial automation. The model follows the 8LSA designation code, indicating the standard mechanical build without reinforced bearings, and it is supplied as product revision 3. The motor connects to a compatible inverter so the control system can command torque and speed precisely during repetitive manufacturing or assembly sequences.
The motor has a rated speed of 4500 rpm, providing high operating velocity for demanding motion profiles. Its square mounting interface has a flange dimension of 91.3 mm, allowing installation in machine frames designed for its mounting dimensions. Rotor position is reported by a resolver, which provides analog sine-cosine feedback suitable for electrically noisy environments. Thermal management relies on self-cooling with free air circulation, so ambient air moving around the housing removes heat without an external blower. Positional repeatability is maintained within 6 arcmin, supporting indexing tasks that require moderate precision. The motor is supplied without a holding brake, so an external holding mechanism may be necessary when a load must remain stationary after power is removed. It also lacks an oil seal, making an external barrier necessary where fluids or contaminants could reach the shaft opening. Connection hardware consists of a single keyed connector for the motor cabling, while length code 6 indicates the active stack height associated with the motor configuration.
Power and feedback fittings exit the stator through an angled swivel connector, allowing cable routing to clear adjacent components in compact installations. Output torque is delivered through a smooth shaft, which supports tapered or clamping collars when coupling backlash must be minimized. A mounting flange with pilot registers aligns the motor concentrically with gearboxes or driven loads. The motor uses a three-phase synchronous design, which keeps the permanent-magnet rotor synchronized with the commanded stator field. This operating principle supports responsive torque control and stable speed regulation across repetitive motion cycles.
