- Q1. What is servo drive?
- Ans.
A servo drive is an electronic amplifier used to power and control the motion of a servo motor.
Converts low-power control signals into high-power electrical currents to drive the servo motor
Provides precise control over speed, position, and torque of the motor
Commonly used in robotics, CNC machines, and industrial automation systems

- Q1. What is UPS/inverter ? How it works.
- Ans.
UPS/Inverter is an electronic device that provides backup power during power outages or fluctuations.
UPS stands for Uninterruptible Power Supply while Inverter converts DC power to AC power.
UPS provides instant backup power during power outages while Inverter provides backup power after a few seconds of power outage.
UPS is commonly used for computers, servers, and other critical equipment while Inverter is commonly use...
- Q2. Tell about IGBT/MOSFET
- Ans.
IGBT/MOSFET are types of transistors used in power electronics.
IGBT stands for Insulated Gate Bipolar Transistor and is used for high voltage and high current applications.
MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor and is used for low voltage and low current applications.
Both IGBT and MOSFET are used as switches in power electronics.
IGBT has a higher switching speed than MOSFET but MOSFET has a...
- Q3. Basic component of electronics
- Ans.
The basic component of electronics is the resistor, capacitor, and inductor.
Resistor: limits current flow
Capacitor: stores electrical charge
Inductor: stores electrical energy in a magnetic field
Diode: allows current to flow in one direction
Transistor: amplifies or switches electronic signals
- Q4. Transformer working
- Ans.
Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They consist of two coils, primary and secondary, wound around a magnetic core
When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil
This voltage can be stepped up...
- Q5. Why you want to join this field/ company

- Q5. How many io card use in machine
- Ans.
The number of IO cards used in a machine varies depending on the specific machine and its requirements.
The number of IO cards used in a machine depends on the complexity and functionality of the machine.
Different machines may require different types and quantities of IO cards.
IO cards are used to interface between the machine's control system and external devices or sensors.
Some machines may require multiple IO cards t...
