Moving ahead in industry 4.0

With the advent of Industry 4.0, intelligent production is assuming a bigger and bigger role. Servo motor controllers play a vital part in this trend with their ability to provide precise angular positioning of the motor shaft. 

Avnet’s the STM Servo Motor Controller is a servo motion control solution for robots, automation equipment and servo control in industrial applications. This solution comes with an FOC arithmetic that enables servo position control with high efficiency, high reliability and low noise. Its servo position controller also features a sensor with an encoder resolution of 0.09 degrees. The STM32 Servo Motor Controller offers a simple solution that helps developers accelerate their design process.
