8LSC74.EA045D011-3
The 8LSC74.EA045D011-3 from B & R Automation belongs to the advanced 8LS Synchronous Motors series, designed for precision motion control in industrial applications. This robust three-phase synchronous motor features a Motor Flange Size of 74 mm and an Output Shaft Design with a Keyway for secure coupling. Rated for 400 V AC operation, it delivers high efficiency at a Rated Speed of 4500 rpm and supports a Max Speed of up to 6000 rpm. Manufactured to Product Revision 3 standards, the unit complies with rigorous quality benchmarks, offering reliable performance in demanding environments.
Featuring a reinforced bearing arrangement, the motor’s Configuration Summary is specified as 8LSC: Reinforced A-side bearing, ensuring exceptional load capacity and durability. The integrated Connection Hardware utilizes a high-reliability Connector interface for streamlined installation and maintenance. An inductive encoder with Turn Capability of Single-turn and EnDat Version 2.1 provides absolute position feedback, eliminating the need for homing sequences. The smooth Shaft End design and absence of an Oil Seal further simplify maintenance, while the Length Code 4 configuration ensures consistent mounting dimensions across the 8LSC family.
Operational efficiency is enhanced by a Cooling Principle based on a Built-in fan assembly, effectively reducing the motor’s thermal time constant and enabling sustained high-power output. The Degree Of Protection IP65 rating guards against dust ingress and water jets, ensuring reliable operation in harsh industrial settings. With a Flange Dimension of 190 mm and a Shaft Length of 45 mm, the motor achieves optimal heat dissipation through direct chassis mounting. These features combine to deliver stable torque characteristics, low vibration, and reduced maintenance intervals, maximizing uptime and productivity.
Integration of the 8LSC74.EA045D011-3 into existing automation platforms is straightforward thanks to its standardized mechanical and electrical interfaces. The Connector-based power and feedback connections facilitate rapid commissioning with minimal wiring effort. Its compatibility with B & R Automation control architectures makes it ideal for applications in robotics, material handling, packaging, and machine tooling. By leveraging the motor’s high-speed capability, reinforced bearings, and robust IP65 protection, system designers can achieve compact, high-performance drive solutions tailored to modern manufacturing challenges.
