8LSA44.EA030D100-3

The 8LSA44.EA030D100-3 is a high-performance servo motor from B & R Automation in the 8LS Synchronous Motors series. This compact unit features a Rated Power (PN) of 1.45 kW and delivers a Rated Torque of 10.0 Nm with a Holding Torque of 13.5 Nm, making it ideal for precision industrial automation. With a Frame Size of 44 and a robust design, it maintains exceptional accuracy and efficiency even under demanding conditions. The motor’s Protection Class IP65 rating ensures reliable operation in harsh environments, while its Rated Speed of 3000 rpm supports dynamic motion requirements.

This three-phase synchronous drive excels in technical capability through its advanced construction: it employs Inductive EnDat encoder technology with EnDat Version 2.1, offering absolute feedback without batteries. The Connection direction angled (swivel) design simplifies installation, and the Mounting Availability flange option facilitates versatile mounting configurations. With a Length Code 4 and Flange Dimension of 100 mm, integration into existing machinery is straightforward. Electrical performance is defined by a Stall Current of 2.77 A and stable thermal behavior under full load. The Configuration Summary 8LSA: Standard, no reinforced bearing underscores its balance of rigidity and dynamic response.

Operational reliability is delivered through a combination of self-cooling technology and durable materials. The Cooling Principle self-cooling, free circulation ensures optimal thermal management, complemented by a thermal time constant ranging from 15 to 30 minutes depending on size. Vibration is classified as R severity per IEC 60034-14, reducing wear and acoustic noise. Insulated to Class F with a maximum winding temperature of 145 °C and a thermal protection limit of 110 °C, the motor withstands extended duty cycles. Additionally, its high overload capability and optional oil seal upgrade to Protection Class IP65 offer maintenance-free performance in dusty or wet environments.

Integration is seamless thanks to its precise shaft design: the Shaft End with key meets DIN 748 standards and supports optional holding brake functionality to secure load position on power loss. The compact weight of 3.1 kg and a moment of inertia of 0.9 kg·cm² facilitate rapid acceleration and deceleration in automated systems. Maximum installation altitude of 2000 m and a tolerance to 10% voltage drop above 1000 m ensure global usability. Ideal for machine tools, packaging equipment, and robotic applications, the 8LSA44.EA030D100-3 offers engineers a dependable solution for complex motion control challenges.
