The 380 series AC servo motor is a type of servo motor commonly used in industrial automation applications. It is a high-speed, low-torque motor that is designed to operate at high speeds while maintaining a constant torque output. This makes it well-suited for applications such as robotics, machine tools, and other precision equipment where precise control is required. The 380 series AC servo motor is typically powered by an AC power source and controlled using a servo controller or other electronic control system.
