- Q1. What is the teransform
- Ans.
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are commonly used to step up or step down voltage levels in electrical systems.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.
The primary coil is connected to the input voltage source, while the secondary coil is connected to the outpu...
- Q2. What is the current
- Q3. What is the voltage
- Ans.
Voltage is the difference in electric potential between two points.
Voltage is measured in volts (V).
It represents the potential energy per unit charge.
Voltage is the driving force that pushes electric current through a circuit.
- Q4. What is the ohm's low
- Ans.
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
Ohm's Law is represented by the formula V = IR, where V is the voltage, I is the current, and R is the resistance.
It helps in calculating the current flowing through a circuit when the voltage and resistance are known, or determining the r...

(3 Questions)
- Q1. What's your country current frequency
- Q2. 1 kilovolt-ampire what volt
- Q3. 1 hp what kilo watt
- Ans.
1 horsepower is equal to approximately 0.746 kilowatts.
1 horsepower (hp) is a unit of power commonly used in the field of engineering.
1 kilowatt (kW) is a unit of power commonly used in electrical systems.
To convert horsepower to kilowatts, multiply the horsepower value by 0.746.
For example, if you have 2 horsepower, it would be equal to 1.492 kilowatts.

- Q1. VFD output formula
- Ans.
VFD output formula calculates the output voltage and frequency of a variable frequency drive.
The formula is Vout = Vin x (2/√3) x (Fout/Fin)
Vout is the output voltage, Vin is the input voltage, Fout is the output frequency, and Fin is the input frequency
The formula assumes a three-phase system
The output frequency can be adjusted to control the speed of the motor
Example: If Vin is 480V, Fin is 60Hz, and Fout is 30Hz, th
- Q2. How output VFD drop
- Ans.
Output VFD drops due to various factors such as overloading, voltage fluctuations, and motor issues.
Overloading of the motor can cause the VFD output to drop.
Voltage fluctuations can also cause the VFD output to drop.
Issues with the motor, such as a faulty winding, can cause the VFD output to drop.
Inadequate cooling or ventilation can cause the VFD output to drop.
Incorrect programming or settings can cause the VFD outp
- Q3. How to communicate plc and hmi
- Ans.
PLC and HMI can communicate through various protocols such as Ethernet/IP, Modbus, Profibus, etc.
PLC and HMI can be connected through a physical cable or wireless connection
PLC sends data to HMI through the chosen protocol
HMI displays the data received from PLC and sends commands back to PLC
Programming software is used to configure the communication settings
Examples of protocols used for communication are Ethernet/IP,
- Q4. Diff between VFD and servo
- Ans.
VFD is used to control the speed of AC motors, while servo is used for precise control of position, speed, and torque.
VFD is used for variable speed control of AC motors
Servo is used for precise control of position, speed, and torque
VFD is typically used in applications where speed control is the primary concern
Servo is typically used in applications where precise control of position, speed, and torque is required
VFD i...
- Q5. How encoder work's
- Ans.
Encoders are devices that convert motion into an electrical signal.
Encoders can be rotary or linear
They work by detecting changes in position or motion
They can be absolute or incremental
Examples include optical encoders and magnetic encoders
