8Lsa57.Eb022d004-1

Product Description:

The 8Lsa57.Eb022d004-1 is part of the 8LS Synchronous Motors series made by B & R Automation, built to deliver consistent motion without overcomplicating things. The shaft is just 14 mm in diameter, so it fits well in tight mechanical assemblies. Weight sits around 8 kg, which is manageable for smaller equipment or frames where loading needs to stay light. This model pushes out 0.37 kW of mechanical power — enough for light-load tasks like positioning stages or conveyor systems. Cooling setup is totally enclosed fan-cooled (TEFC), so airflow is internalized, meaning fewer chances for external contaminants to mess with the internal parts.

Mounting configuration is B3, so it bolts down in horizontal setups without flanges. IP55 protection is built in, blocking most dust and guarding against splashing water from any direction. Duty type S1 means it runs continuous without heat derating, which is helpful in production lines where motors don’t shut off between cycles. Rated speed is 3000 rpm, and the frequency holds steady at 50 Hz. Voltage range is 230/400 V, which allows flexible hookup to common supply systems in industrial regions.

The frame size marked 8LSA57 places it in the compact class of the series, often chosen for systems needing a bit more than stepper-level torque but not big enough for oversized servo drives. Built more for function than for marketing sheets — just solid specs, tight design, and nothing fancy. Most units like this end up in textile equipment, labeling systems, or light automation arms where reliability takes priority over flashy extras. When TEFC, IP55, and clean performance are what’s needed, this motor just fits in and does the job.
