Product Description:

The 8LSA25.D8060S100-3 is a synchronous AC motor engineered by B & R Automation, with an input source requirement of 3x 400 to 3x 480 VAC, ±10% voltage tolerance. It is designed as a self-cooling unit and its mounting system is flange-based, though it can be fitted vertically or horizontally depending on the system.

The 8LSA25.D8060S100-3 motor features a top located connector with a 270-degree rotatable angular outlet. It delivers a rated torque of 0.52 Nm and a stall torque of 0.6 Nm. The motor’s peak torque reaches 2.4 Nm to enable high dynamic performance and its supported top speed reaches up to 9000 RPM. It consumes a rated power of 327 W and make use of an EnDat inductive encoder, designed for safety compliant feedback. The 8LSA motor possess a torque constant of 0.73 Nm/A and the voltage constant is measured as 43.98 V for every 1000 spins. It operates at a rated current of 0.71 A, with a peak current capacity of 3.7 A and its winding impedance is 34.63 Ohms at 20°C along with an inductive value of 49.6 mH, that contributes in smooth and controlled functionality. The 8LSA motor’s rotor inertia is 0.16 kg·cm² to provide fast response and it weighs about 1.3 kg, without a holding brake.

The 8LSA25.D8060S100-3 motor is IP65 protected, that makes it suitable for harsh and derated industrial environments. Its class F electrical insulation allows operations up to 428.15 K temperatures and its maximum installation elevation ranges up to 3300 ft. Further extension from these values derates the torque and current by 5%. The 8LSA motor’s integrated holding brake provides 2.20 Nm of static torque to maintain position during power loss or shutdown.
