Abstract

"The elaboration of norms for classifying electric motors in energy efficiency classes has stimulated research on identifying solutions to reduce losses in electric cars in terms of maintaining overall dimensions and functional performance. Variable reluctance synchronous motors are a practical solution for the super premium, IE4, and ultra premium, IE5 energy efficiency classes, in a number of applications of electric drive systems for drinking water supply, wastewater disposal, ventilation and installations in the food industry. The paper presents a study of numerical models regarding the correlation of the number of stator notches with the number of rotor field barriers of a variable reluctance synchronous motor to reduce electromagnetic torque oscillations."
