Product Description:

B&R Automation 8MS Three Phase Synchronous Motors module, 8MSA5M.R0-Y1, is a small but strong servo motor designed for performance in multiple automation systems.

Rated output power is 300 W, with a rated voltage of 200 V, being optimal in energy efficiency to carry out light-to-medium duties in motion control. Its motor has a rating of 2.1 A and delivers a torque of 0.95 Nm. It runs at 3000 rpm to give a smooth and responsive low-power drive, such as pick-and-place machines, small-scale robotics, and conveyor drives. To provide dynamic performance, it has a peak torque of 2.8 Nm, which allows acceleration and precise positioning in rapid or sudden load changes as well. The motor is fitted with a high-resolution absolute encoder of 23-bit resolution to provide a reliable and accurate position feedback that is needed in a complex task of automation. It has an IP65 degree of protection that is fully shielded against dust intrusion and water jets, so it is not concerned with unpredictable environments or environments with contaminants.

The self-cooling ability, which is based on an air convection mechanism, makes it easier to install without externally requiring any outside cooling, which generally stabilizes temperatures. Flange pressing allows the easy and safe mounting of machinery. Boasting a top speed of 6000 rpm, this motor can handle any high-speed application. When executing high-dynamics jobs, the rotor's low moment of inertia of about 0.15 kg · cm² enables good acceleration and deceleration qualities. With a thermal class rating of 155 (F), it is made to survive high temperatures and operate dependably in a temperature range of 0 °C to +40 °C. The product, which weighs around 1.9 kg, is a space-restricted automation system with exceptional performance, precision, and durability.
