Fast Method for the Iron Losses Prediction in Inverter Fed Induction Motors [PDF]

, 2009
In this paper an easy method for the iron loss prediction in PWM inverter fed induction motors is presented. The method was initially proposed and validated for the prediction of the iron losses in non-oriented soft magnetic material with PWM supply ...

Iron Losses Prediction with PWM Supply Using Low and High Frequency Measurements: Analysis and Results Comparison [PDF]

, 2008
In this paper, two different methods for iron loss prediction are analyzed. The first method is based on the classical separation of loss contributions (hysteresis, eddy-current, and excess losses).

Finite-Element Modeling and Characterization of Iron Losses in 12 mm Thick Steel Laminations Including the Effect of Cutting

IEEE Access, 2021
Iron losses in laser-cut toroidal samples of 12 mm thick steel laminations used in large synchronous motors are studied. Eddy currents in the lamination cross-section are solved with the 2-D finite element method while applying a constitutive law based ...

The Dermal Loss of Iron.

Experimental Biology and Medicine, 1950
Summary“Cell poor” and “cell rich” sweat samples from 25 normal subjects have been analyzed (total of 118 determinations). The iron content of “cell poor” sweat was negligible. On the other hand “cell rich” sweat contained a high concentration of iron.

Calculation for stator loss of high-speed permanent magnet synchronous machine in torque-speed envelope and restraint approach for circulating current in windings

CES Transactions on Electrical Machines and Systems, 2018
Iron loss and copper loss are the significant parts of electrical loss of machines, which are the major parts particularly under high frequency condition. High-speed permanent magnet synchronous machines (HS-PMSM) have the benefits of high power density,
