Product Description

A state-of-the-art AC synchronous servo motor, the 8MSA6S.R0-B400-1 is designed for certain industrial applications and is suitable for use in such applications. The rotor of the motor is made up of a permanent magnet, and it has a nominal torque of 4.00 Nm and a nominal velocity of 3000 revolutions per minute.

In order to function normally, this motor needs a nominal voltage of 400 V and a current of 7.6 A. However, it is capable of reaching 22.8 A when subjected to heavy-duty applications. There is also the possibility of relying on the motor in dynamic conditions, where its stall torque is 4.76 Nm. The inertia of this motor is 1.03 kilogrammes per square centimetre, which enables it to regulate motion rapidly. Through the use of the resolver, which provides feedback for the 8MSA6S.R0-B400-1, it is possible to accomplish precise motion placement and control of automated systems. Natural convection is the cooling method used for the motor, eliminating the need for external devices whose reliability cannot always be guaranteed. Additionally, the motor is protected from dust and water by being housed in a casing that has an IP65 rating, enabling it to be used in heavy industrial settings.

This particular motor, which has a braking system weighing 0.9 kilogrammes, makes it easier to exercise more control in situations that call for retaining torque. Having received CE certification, the 8MSA6S.R0-B400-1 meets worldwide safety and quality norms. As a result, it can be relied upon to carry out a variety of automation duties in an effective and efficient manner.
