🔍 What is a Servo Motor?
A Servo Motor is a high-performance electric motor that offers precise control over speed, position, and torque. It’s commonly used in automation systems where exact movement is essential — like CNC machines, robotics, packaging lines, and injection molding equipment.
🔌 What is a Servo Drive?
A Servo Drive (or Servo Amplifier) is the controller that manages the power and signals sent to the servo motor. It receives commands from the main control system (like a PLC or motion controller), processes feedback from the motor, and adjusts performance in real-time for precise motion control.
