Electric motor of alternating current has as principle of operation the magnetic flux

The alternating current electric motor has as its principle the magnetic flux both in time and space (sinusoidal), so as to produce a force in the air gap and this causes the rotor to rotate with defined torque.

By analyzing the loss equations, it is necessary to verify that there are ways to reduce the magnetic losses in the electric motor and this can decrease both losses through hysteresis and dynamic losses.

The reduction of this hysteresis loss in the electric motor involves metallurgy and materials, but there are processes in the production of electric machines that have a direct influence on the loss as the stamping of the blades, the heat treatment, the pressure exerted on the blades and many others.

When losses in the electric motor skf 61905 2rz are called dynamic losses, you can reduce reducing the thickness of the blade or even increasing the electrical resistance of the electric motor by incorporating silicon into the steel. When all these factors are optimized, all that remains is to improve all the details that are considered constructive in the electric motor.
