Product Description:

The 8MSA3M.R0-B4 servo motor by the company B&R Automation is used in rotational and heavy-duty tasks and control solutions. B&R Automation is the producer of this motor and it develops efficient designs to meet rigorous industrial automation standards with high-class performance.

The 8MSA3M.R0-B4 servo motor works under three-phase electricity supply. Being a synchronous motor, it has a fixed speed regardless of the load conditions providing reliable and constant performance. It does not need outside ventilation and is cooled by self-cooling by making installation and maintenance demands easy. This model comes with size 3 of the series which produces medium-rated torque with 1.2 Newton meter output which can be very assistive to an application with rotational force requirement. It has a resolver that provides feedback required in proper detection of rotor position which is essential in maintaining synchronization in motion control tasks. The rated speed is which stands at 3000 rpm and it can perform other duties that require steady rotation. It also weighs 2.5 kg which is very easy to handle during replacement or storage conditions.

The 8MSA3M.R0-B4 servo motor uses an input current of 0.95 A that is drawn through it and aids efficient power usage as well as dynamic torque generation. It has an IP64 rating which prevents dust and water drop entry to protect the unit against any harm. There is no matched fan or brake and it is a fanless structure which is useful in a situation where noise reduction and less air contamination are a priority. The lack of a brake implies that it is not to be used in systems where holding torque in the powered-off condition is controlled externally.
