Product Description:
The 8LSA36.S1045C200-0 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. It delivers rotary motion for axes that require accurate speed and position control in automated assembly cells, conveyors, and robotic systems. The motor converts electrical commands from a compatible servo drive into controlled mechanical movement at the connected load. Its digital feedback system supports closed-loop operation, while the compact frame helps conserve installation space in machinery with closely arranged motion components.
Thermal management relies on self-cooling through free air circulation, eliminating the need for an external blower. The rotor reaches a rated speed of 4500 rpm, supporting applications that require fast movement and short cycle times. A mounting flange measuring 91.3 mm allows attachment to compatible gearboxes or machine plates that use the corresponding mounting pattern. Position feedback is generated by an optical EnDat encoder that uses the EnDat 2.2 protocol to transmit absolute position data over a bidirectional serial connection. The measuring system provides 25-bit single-turn and 12-bit multi-turn resolution, enabling precise position tracking within each mechanical revolution and accurate counting across multiple revolutions. This feedback allows the connected drive to monitor rotor position without relying solely on estimated movement from commanded speed.
A standard holding brake secures the shaft when power is removed, helping prevent vertical or suspended loads from moving unexpectedly. The smooth shaft connects directly to backlash-free clamping hubs without requiring a keyed coupling. Power and feedback cables exit through a straight top connector, which supports direct cable routing in compact machine assemblies. The encoder provides a multi-turn range of 4096 revolutions, preserving absolute position information across power cycles within that operating range. The motor has no oil seal, so shaft protection must be provided by a suitable external housing or by operating the unit in dry conditions. This arrangement avoids seal friction at the shaft while requiring the surrounding machine design to limit exposure to oil, moisture, and other contaminants.
