  1. What is a servo drive? Answer: A servo drive is an electronic controller used to control the position, speed, and torque of a servo motor with high accuracy. It supplies power to the motor and continuously corrects its motion using feedback. 2. What is the difference between a servo motor and a servo drive? Answer: Servo Motor: Converts electrical energy into mechanical motion Servo Drive: Controls the motor by providing power and control signals A servo motor cannot operate without a servo drive. 3. What are the main components of a servo system? Answer: Servo Motor Servo Drive Feedback device (Encoder / Resolver) Controller (PLC / CNC) Power Supply   4. What is the main function of a servo drive? Answer: The main function of a servo drive is to: Supply controlled power to the motor Read feedback signals Calculate error Correct motor movement in real time   5. On which princi...

1. Question: What is an electric circuit? Answer: An electric circuit is a closed loop through which electric current can flow, composed of various components like resistors, capacitors, and inductors. 2. Question: Define voltage? Answer: Voltage, also known as electric potential difference, is the force that drives electric charges to move in a circuit. It's measured in volts (V).  3. Question: What is Ohm's Law? Answer: Ohm's Law states that the current through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance or V=IR.  4. Question: Explain the concept of resistance? Answer: Electrical resistance is defined as the property of an electrical component to resist the flow of electric current. It's measured in ohms (Ω). 5. Question: Differentiate between AC and DC? Answer: AC (alternating current) changes its direction periodically, while DC (direct current) flows in one direction consistently.   6. Question:...
