8LSA35.E2030D200-0

The 8LSA35.E2030D200-0 synchronous servo motor from B & R Automation is part of the 8LS Synchronous Motors series and is engineered for precision motion control in industrial automation. This three-phase synchronous motor delivers a rated voltage of 230 V and a rated power of 2.0 kW, providing a rated torque of 6.37 Nm at a rated speed of 3000 rpm. Featuring an IP65 protection class (except shaft), the unit is sealed against dust and water ingress under normal industrial conditions. The design incorporates a mounting flange with a diameter of 91.3 mm, ensuring straightforward mechanical integration and acting as an additional cooling surface. With a product revision of 0 and a compact form factor (Length Code 5), this motor balances high performance with installation flexibility.

Performance is driven by a robust self-cooling free circulation system that dissipates heat through natural convection across the mounting flange and housing. The motor employs a single-turn EnDat 2.2 absolute encoder for high-resolution position feedback, enabling precise closed-loop control. Connection is facilitated through an angled swivel connector compatible with standard industrial cabling, while the absence of an oil seal simplifies maintenance without compromising protection. The standard holding brake is integrated directly behind the flange, offering secure load-hold capability when power is removed. With a smooth shaft end and a configuration summary of standard bearings, the device supports continuous S1 operation as per EN 60034-1, providing consistent torque under sustained load conditions.

Reliability is further enhanced by the three-phase synchronous design, which minimizes vibration and extends lifespan under continuous-duty cycles. The robust connector hardware guarantees secure electrical interfaces, while the motor’s self-cooling principle reduces the need for external fans or liquid cooling circuits. Regular cleaning of the flange and housing surfaces is recommended to maintain optimal thermal performance and prevent brake torque degradation due to contamination. Integration into existing drive systems is simplified by its standardized connector, flange dimensions, and revision compatibility, ensuring seamless replacement or upgrade paths. Ideal applications include CNC machinery, packaging lines, pick-and-place systems, and other industrial automation scenarios where precise torque control, long service life, and IP65-level protection are essential.
