8LSA35.R0045D000-0

The B & R Automation 8LSA35.R0045D000-0 servo motor from the 8LS Synchronous Motors series is a flange-mounted, three-phase synchronous drive designed for industrial automation. It delivers a continuous torque of 1.8 Nm and a peak stall torque of 2.3 Nm while operating on a 400 V three-phase supply. With a frame size of 35, the motor achieves a rated speed of 4500 rpm across four poles and is protected to IP65 standards for dust and water ingress. Feedback is provided by a resolver system ensuring a positioning precision of 10 arcmin for high accuracy motion control tasks. The motor’s thermal class of F and RAL-coated housing enable reliable operation in ambient temperatures up to 40°C and at installation altitudes above 1000 m.

The technical construction of the 8LSA35.R0045D000-0 features a Mounting Availability: Mounting flange interface with a Flange Dimension: 91.3 mm, providing secure attachment in modular machine designs. Electrical connection is made via a robust Connector and the stator inductance is specified at 21.7 mH for controlled current response. The Length Code: 5 and Product Revision: 0 define the overall motor depth and manufacturing iteration, while a smooth shaft end offers compatibility with standard couplings or pulleys. No oil seal is present, streamlining maintenance procedures and reducing frictional losses at the shaft entrance. The motor configuration summary is noted as 8LSA: Standard, no reinforced bearing, emphasizing a balance between performance and cost in factory automation systems.

Operational performance of the 8LSA35.R0045D000-0 is characterized by its maximum angular acceleration of 102222 rad/s², enabling fast start-stop cycles in pick-and-place and indexing applications. The rated power output of 0.85 kW ensures efficient drive of conveyor belts, rotary indexing tables, and CNC positioning axes. A recommended motor cable cross-section of 1.5 mm² supports consistent power delivery and minimizes voltage drop over moderate cable lengths. The absence of an oil seal reduces mechanical drag and contributes to lower heat generation, complementing the Thermal Class F insulation that handles elevated winding temperatures. Environmental resilience is further enhanced by the IP65 housing and RAL paint finish, which resist corrosion and particulate buildup in harsh shop-floor conditions.

System integration with the B & R Automation ecosystem is streamlined through compatibility with standard servo controllers and motion libraries in Automation Studio. The resolver feedback eliminates homing cycles and battery backup requirements, reducing system complexity and maintenance points. Its compact frame size 35 and flange-mount design make it ideal for robotics joints, compact CNC spindles, packaging machinery, and automated assembly platforms. This motor is optimally suited for industries requiring precise, high-density motion control under demanding environmental conditions.
