8LSA35.DB030S200-3

The 8LSA35.DB030S200-3 synchronous servo motor from B & R Automation is a precision drive solution in the 8LS Synchronous Motors series, designed for demanding industrial automation tasks. This motor delivers a Rated Speed of 3000 rpm and a Nominal Torque of 2.1 Nm, with a stall torque rating of 2.3 Nm. It provides an output power of 660 W, while its design supports a maximum rated power of up to 4.5 kW. The compact frame size of 35 and a stator length coded as S ensure compatibility with space-constrained installations. Protection to IP65 standards guarantees robust performance in harsh environments, and the motor length of 200 mm balances torque output with a streamlined footprint.

The motor’s dynamic characteristics are optimized through an Electrical Time Constant of 5.2 ms and a stator inductance of 63 mH, which facilitate rapid current response during transient load conditions. A Voltage Constant of 87.96 V/1000 rpm and a Torque Constant of 1.45 Nm/A ensure efficient energy conversion and consistent torque delivery across its speed range up to a maximum of 9000 rpm. Current demands are modest, with a Nominal Current of 1.4 A and a Stall Current of 1.6 A, reducing thermal stress in continuous operation. The motor’s stator resistance of 12.22 Ω and moment of inertia of 0.9 kg·cm² contribute to controlled acceleration profiles and precise motion control. Four pole pairs enhance electromagnetic smoothness and low cogging torque, enabling high-resolution positioning.

Reliability and integration are assured through a standard Holding Brake offering 4 Nm of brake torque, and a keyed smooth shaft interface for secure mechanical coupling. Connection is managed via robust flying leads and a dedicated connector, while the flange dimension of 91.3 mm aligns with common industrial mounts. Feedback is provided by an inductive EnDat 2.2 multi-turn absolute encoder, supplemented by an onboard resolver for redundancy and high-precision feedback. The thermal time constant of 34 minutes and product revision 3 status reflect refined thermal management and component maturity. Engineered for real-time control in complex positioning systems, this motor integrates seamlessly with advanced drive electronics for high-end CNC machines, pick-and-place robots, and precision assembly lines.
