Product Description

The 8MSA4S.R0-30 servo motor is a three-phase motor that is exceptional in its efficiency and provides precise movement. It was developed specifically for use in industrial applications. Due to the fact that it has a rated torque of 0.5 Nm and a peak torque of 1.5 Nm, it is suitable for use in a variety of automation activities and maintains a consistent torque even when subjected to heavy loads. Furthermore, in order to maintain its stability under situations of static load, there is a provision for continuous stall torque of up to 0.8 Nm.

In terms of energy efficiency, this servo motor operates at voltage ratings ranging from 200 to 240 volts alternating current (AC), with a current rating of around 3.2 amperes. This comprises incremental encoders as well as absolute encoders, making it possible for complicated automation systems to provide precise feedback on position and control in a fluid manner. The 8MSA4S.R0-30 has a protection grade of IP65, which guarantees that its operations are not affected by water or dust, making it appropriate for demanding conditions found in industries. In addition, the natural convection cooling approach avoids the need for extra cooling systems, resulting in long-term durability with minimal maintenance requirements.

It weighs only 2.6 kilogrammes and has a flange size spanning 80 millimetres by 80 millimetres. Additionally, it has a shaft diameter of 14 millimetres, which makes it easy to integrate into tight setup requirements. The rotor inertia is about equivalent to 0.65 kilogrammes per square centimetre, enabling faster response times, thus making the motor more dynamic. Through its mix of strength, precision, and energy-saving characteristics, it has been approved by the Underwriters Laboratories (UL), making it a perfect choice for industrial automation applications that need precise motion control.
