8LSA54.R2030D100-3

The B & R Automation 8LSA54.R2030D100-3 synchronous servo motor, part of the 8LS Synchronous Motors series, delivers a balanced combination of power and precision in industrial automation applications. This three-phase synchronous motor provides a nominal output of 2419 W with a rated torque of 2.0 Nm at a rated speed of 3000 rpm, operating on 230 V supply voltage. The robust frame size 8LSA54 is complemented by a flange dimension of 142 mm and a keyed shaft for slip-free torque transfer. Protection to IP65 ensures reliable operation in dusty or damp environments, while the resolver-type encoder technology offers accurate feedback with 6 arcmin precision. The motor’s Configuration Summary (8LSA: standard, no reinforced bearing) and Length Code 4 provide a compact, maintenance-friendly design for tight mechanical layouts.

Performance is optimized through carefully matched electrical characteristics, starting with a voltage constant of 98.44 V/1000 rpm and a torque constant of 1.63 Nm/A, which together yield efficient energy conversion and stable torque delivery under varying load conditions. The stator resistance of 2.16 Ω and stator inductance of 21.52 mH influence voltage drop and current ripple, supporting smooth current flow and improved power factor. A stall current of 5.5 A and a maximum current of 20.9 A allow high torque generation during dynamic start-stop cycles, while the electrical time constant of 10.6 ms ensures controlled transient response. Class-F insulation per EN 60034-1 supports a maximum winding temperature of 155 °C, reducing thermal stress during continuous operation. Connection is handled via a robust connector with an angled (swivel) connection direction to simplify cabling in complex system assemblies.

Reliability is further reinforced by the motor’s insulation class F and sturdy enclosure, delivering consistent performance in industrial environments. The use of a resolver encoder provides high immunity to electrical noise and secure closed-loop control, critical for precision positioning tasks. With no holding brake, the motor is optimized for applications where external braking systems are preferred or integrated. Its compact design and IP65 rating make the 8LSA54.R2030D100-3 ideal for packaging machinery, conveyor systems, and robotic actuators in industrial automation. When combined with B & R Automation servo drives, it supports advanced features such as torque ripple compensation, auto-tuning, and synchronous multi-axis synchronization.
