Tata Cummins Diploma Trainee Interview Questions and Answers for Freshers

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.

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...read more

Newtons law of motion describes the relationship between an object and the forces acting upon it.

• First law states that an object at rest will remain at rest and an object in motion will remain in motion with a constant velocity unless acted upon by an unbalanced force.

• Second law states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.

• Third law...read more

There are two types of satellite communication: geostationary and low earth orbit.

• Geostationary satellites are placed at a fixed point above the earth's equator and are used for TV broadcasting, weather forecasting, and military communication.

• Low earth orbit satellites are placed closer to the earth's surface and are used for GPS, satellite phones, and remote sensing.

• Satellite communication is important for global conn
