Ashok Leyland Maintenance Associate Interview Questions and Answers

Q1. How to calculate motor fl current
Ans. 
Motor full load current can be calculated using the formula: FLA = (P x 746) / (V x Eff x PF x 1.73)
• Calculate the power (P) of the motor in horsepower

• Determine the voltage (V) of the motor

• Find the efficiency (Eff) of the motor

• Identify the power factor (PF) of the motor

• Use the formula FLA = (P x 746) / (V x Eff x PF x 1.73) to calculate the full load current

Q2. What is ammeter how it is working
Ans. 
An ammeter is a device used to measure electric current flowing through a circuit.
• Ammeters are connected in series with the circuit in which the current is to be measured.

• They have a low resistance to prevent significant voltage drop in the circuit.

• Ammeters are calibrated in units of amperes (A) or milliamperes (mA).

• They typically have a needle or digital display to indicate the current reading.

• Ammeters can be analog o

Q1. How the start industion motor...??
Ans. 
To start an induction motor, apply a voltage to the stator windings to create a rotating magnetic field.
• Apply a voltage to the stator windings to create a rotating magnetic field

• The rotating magnetic field induces currents in the rotor windings, causing it to start rotating

• Use a starter or a soft starter to control the starting current and reduce stress on the motor

• Ensure proper maintenance of the motor to prolong its
