Product Description:
The 8LSA45.DA030S200-3 is a three-phase synchronous motor manufactured by B&R Automation within the 8LS Synchronous Motors series. Intended for precision motion tasks in automated assembly, packaging, and material-handling cells, the unit converts electrical power into regulated rotary motion for actuators that require repeatable speed or position. The motor operates with a compatible servo drive that regulates current in response to motion commands and changing loads. This arrangement supports controlled acceleration, steady rotation, and accurate stopping during repetitive machine cycles.
The motor has a rated speed of 3000 rpm, providing a predictable operating point for motion applications. Its 100 mm flange supports direct attachment to a compatible gearbox or machine plate. Power, feedback, and brake conductors use a single-cable hybrid connection, so only one cable needs to be routed to the axis. Rotor position is reported by an inductive EnDat encoder that communicates through an EnDat 2.2 interface for digital feedback. A factory-installed standard holding brake locks the shaft when power is removed, helping prevent load drift on vertical or indexing axes. The brake can secure a stationary load when drive torque is unavailable, while the encoder supplies the position information required for closed-loop motion control.
Thermal regulation relies on self-cooling through free air circulation, allowing the housing to dissipate heat without forced ventilation. Feedback has a 19-bit single-turn and 0-bit multi-turn resolution, providing precise angular position data without multi-turn revolution tracking. The motor is equipped with a smooth shaft, which avoids keyway stress concentrations and supports clamp or friction couplings. It also has no oil seal, making the shaft interface suitable for dry applications that do not require an external oil barrier. Proper spacing around the housing allows ambient air to carry heat away during operation. Coupling alignment and shaft loading should remain within the limits of the connected equipment to reduce unnecessary bearing stress and preserve consistent rotary motion.
