Product Description

The 8MSA4S.E2-73 is similar in application and basic design to the servomotor torre due to its many potential applications. This device is three-phase and has a bipolar supply of 330 volts alternating current with a salient feature of varying frequency, allowing it to adapt to different operating conditions. The 3000 RPM motor functions with efficiency and consistency, making it highly suitable for fast yet accurate operations.

The manufacturer of the motor indicates torque and power rating values, as well as the type of encoding, which can be plastic, brass, steel, or aluminum, depending on the application. It offers a variety of strong housing, with protection levels ranging from IP54 to IP65, safeguarding against dust and water in different environments. The format of the 8MSA4S.E2-73 can be standard or special in design, making it capable of being mounted in various industrial systems, ensuring easy and comfortable installation. The motor operates within a temperature rating of -20 degrees C to +40 degrees C, beyond which the motor becomes inefficient or may fail. For a capped amount of pressure and water, an activator makes the motor more resistant to adverse environments, ensuring that the outer casing remains intact when used under such conditions.

This servomotor also passed the CE and UL certifications as a Controllers, Devices, and Sensors component, assuring it meets worldwide safety and quality requirements. This makes it highly relevant to industries that face motion control challenges, providing a reliable solution for their needs.
