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...read more

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...read more

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...read more

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, ...read more

Q3. Electrical panel with braking system
Ans. 
An electrical panel with a braking system is a safety feature that automatically stops the flow of electricity in case of an emergency or malfunction.
• The braking system in an electrical panel is designed to prevent electrical accidents and protect both people and equipment.

• It works by detecting abnormal conditions such as short circuits, overloads, or ground faults, and immediately cutting off the power supply.
