“…In addition to the losses in the part of the housing directly adjacent to the stator yoke, additional power losses can also occur in parts of the housing not adjacent to the stator core due to stray fluxes around the stator's winding end connections. So far, this problem has been considered when analyzing losses in the front parts of the core and structural parts, such as the clamping plate and fingers in high-power turbogenerators and induction motors, as well as in the case of canned induction motors [38][39][40][41][42][43][44][45]. These phenomena will be the subject of further work for the authors.…”

Induction motors are a significant consumer of electricity. Therefore, their energy efficiency level plays a vital role in the world’s energy balance. The world’s markets strive to produce motors of efficiency class IE3 or IE4 while maximizing the use of wire and magnetic materials. However, high induction values in the motor core can also lead to significant losses in construction materials, especially in the magnetic motor housing. This article aimed to show how it is possible to determine the distribution of the magnetic field and additional losses in the yoke and the cast-iron motor frame using field-circuit methods to model the motor and to refine the analytical method for calculating these losses at the motor design stage.
