(5 Questions)
- Q1. What is speed difference between stator's rotating magnetic field and rotor's rmf?
- Ans.
The speed difference between stator's rotating magnetic field and rotor's rmf is called slip.
The slip is necessary for inducing current in the rotor and producing torque.
The slip is typically around 1-3% in most induction motors.
Higher slip values can indicate issues with the motor such as overload or mechanical problems.
- Q2. What is induction motor
- Ans.
An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.
Induction motors are commonly used in various applications such as industrial machinery, pumps, fans, and compressors.
They do not require brushes to transfer power to the rotor, making them more reliable and maintenance-free compared to brushed DC motors.
The speed of an induction motor is determined by the frequen...
- Q3. What is synchronisation
- Ans.
Synchronisation is the process of coordinating multiple systems or devices to work together in harmony.
Synchronisation ensures that different components or processes are aligned in time.
It is commonly used in electrical systems to ensure that multiple generators are running in phase with each other.
In data communication, synchronisation is important for ensuring that data is transmitted and received at the correct timi...
- Q4. What is the speed of a rotor with respect to the stator magnetic field in an induction motor?
- Ans.
The speed of a rotor with respect to the stator magnetic field in an induction motor is known as slip speed.
The slip speed is the difference between the synchronous speed of the rotating magnetic field in the stator and the actual speed of the rotor.
It is necessary for the rotor to operate at a speed slightly slower than the synchronous speed in order to induce current and generate torque.
The slip speed allows the roto...
- Q5. What is slip? Per unit slip?
- Ans.
Slip is the difference between synchronous speed and actual rotor speed in an induction motor. Per unit slip is the slip expressed as a fraction of synchronous speed.
Slip is the difference between synchronous speed (speed of the rotating magnetic field) and the actual rotor speed in an induction motor.
Per unit slip is the slip expressed as a fraction of synchronous speed, typically denoted as a percentage.
For example, ...

- Q1. Electrical mentenanc work experience
- Q2. ElCB full form and MCB full form
- Ans.
ELCB stands for Earth Leakage Circuit Breaker and MCB stands for Miniature Circuit Breaker.
ELCB is a safety device used to protect against electrical shock caused by earth faults.
MCB is a type of circuit breaker that automatically switches off electrical circuits during abnormal conditions.
ELCB detects current leakage to earth and disconnects the circuit, while MCB protects against overloads and short circuits.
- Q3. Earth leakeg circuit breaker and menutur current breaker
- Q4. ElCB sefty protection
- Q5. MCB over load protection
- Ans.
MCB (Miniature Circuit Breaker) provides overload protection by automatically switching off the circuit when current exceeds the rated capacity.
MCB trips when current exceeds its rated capacity to prevent overheating and potential fire hazards.
Overload protection is essential to protect electrical appliances and wiring from damage.
Examples of MCB overload protection include tripping when too many devices are connected ...
