Product Description:

The 8LSA55.EA022D000-3 servo motor is a product from B&R Automation that is specifically designed for industrial automation applications. The motor possesses critical performance attributes, including the ability to operate continuously in a variety of environmental conditions.

As per IEC 60034-1, the 8LSA55.EA022D000-3 servo motor is rated for continuous running and is classified as S1. The environmental temperatures range from -15 degrees C to +40 degrees C, and the maximal flange temperature is 65 degrees C. The motor can only work within these limits. When the temperature goes above 40 degrees C, the ratings and stall currents drop by 10% for every 10 degrees C above 40 degrees C. Within a range of 5% to 95% relative humidity, the motor works without condensate. As per IEC 60034-5, IP64 is the standard for safety. An optional oil barrier can be added to raise the motor's security level to IP65, which makes it more resistant to dust and water getting in. When the motor is put at heights above 1000 meters, this barrier also makes sure that both the nominal and stall currents go down. The motor has a strong design that meets international standards for protecting against and managing temperature, so it will work well in a lot of different settings.

The 8LSA55.EA022D000-3 servo motor makes sure that the system always works the same way. The motor can be put up to 2000 meters above the ground. In high places, it still works well and reliably, so it can be used for many different jobs. In places where the weather and height change, the motor works well. The way the motor is built makes it certain that it will work well and last a long time.
