An analytical motor design-based approach is used to evaluate the major loss components of a premium-efficiency (IE3)four-pole squirrel-cage induction machine. In the analytical approach, the geometry of the machine and the material parameters are used to determine the loss components and they are compared with the ones obtained experimentally with IEC segregation of losses -method. The motor loss components under consideration are the stator copper, rotor copper, iron core, mechanical and additional load (residual)losses. The aim is to test the analytical calculation for further numerical optimization to improve the energy efficiency of the induction motors.
