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
