I applied via Walk-in and was interviewed before Feb 2020. There was 1 interview round.
3ph induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
Three-phase AC power is supplied to the stator winding, creating a rotating magnetic field.
This rotating magnetic field induces a current in the rotor, which in turn creates its own magnetic field.
The interaction between the stator and rotor magnetic fields causes the rotor to rotate, converting e
1 HP is equal to 746 watts.
HP stands for horsepower, a unit of power used in the automotive and manufacturing industries.
Watt is the SI unit of power.
The conversion factor between HP and watt is 746.
I applied via Recruitment Consultant and was interviewed in Jul 2020. There were 3 interview rounds.
Incremental encoder measures relative position changes while absolute encoder measures absolute position.
Incremental encoder generates a series of pulses as the shaft rotates, which are used to determine the relative position change.
Absolute encoder generates a unique digital code for each shaft position, providing absolute position information.
Incremental encoder is simpler and less expensive, while absolute encoder i...

Questions
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
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
