Losses occurs in induction motor are
Rotor loss
Stator loss
Mechanical loss
All of above
All of above
In an induction motor, total losses are broadly classified into Stator losses, Rotor losses, and Mechanical (or friction and windage) losses. Hence, all the given options are valid categories of losses occurring during the conversion of electrical energy to mechanical energy.
In an induction motor, total losses are broadly classified into Stator losses, Rotor losses, and Mechanical (or friction and windage) losses. Hence, all the given options are valid categories of losses occurring during the conversion of electrical energy to mechanical energy.
Electrical power is transferred from the stator to the rotor via electromagnetic induction across the air gap. During this process, energy is lost as I2R (copper) losses in stator and rotor conductors, as core (iron) losses in magnetic laminations due to hysteresis and eddy currents, and as friction/windage losses due to mechanical rotation.
