Intrinsic losses are of two types: fixed losses - independent of motor load, and variable losses - dependent on load . Fixed losses consist of magnetic core losses and friction and windage losses. Magnetic core losses (sometimes called iron losses) consist of eddy current and hysteresis losses in the stator. The major loss components of the induction motor; stator copper losses, rotor copper losses, iron losses, mechanical losses and additional
A method is presented in [10] to predict core losses produced by the harmonic contents of the power supply. Using FEM model of IM, a technique The tests show that both losses are less than would be obtained by the Institute method. The true fixed loss should be taken as the power input, when the motor
Usually, five kinds of losses are considered—losses in stator windings, losses in rotor windings, friction and windage losses, iron losses, and
The model of main losses of an induction machine (IM) consists of stator and rotor losses, mechanical losses, and core losses. Additional losses

What are the losses in induction motor? This type of losses occurs in the stator and rotor cores of induction motor. This type of loss is also called core or magnetic loss. This loss consists of hysteresis and eddy current loss . Both these losses depend on supply frequency and on flux density in the core.
PDF | In this work, an accurate formulation and estimation of stray power losses in induction machines are proposed.
