Nominal power loss on 0.35 mm and 0.50 mm thicknesses of non-oriented steel sheets using Epstein tester frame

Decrease thickness of steel sheets will decrease the total loss especially in core loss and copper loss. This paper presents the effect of thickness in power loss for non-oriented steel sheets. The study was carried out by using an Epstein tester frame for both thicknesses. The data is presented based on 50 Hz. It shows that the thickness of 0.50 mm have more losses compared to 0.35 mm.

The impacts of stator outside diameters on induction motor nameplates: Analysis by using a finite element

Design stimulation by software is important in order to save money and time. This paper is using stimulation software, which is a finite element method, to analyze the stator outside diameter impact on rated current, horse power, power factor and motor efficiency. Then, engineer shall start to build the model after completing the stimulation. The model shall be compare to the stimulation results in order to see the effectiveness.

Efficiency increment of 0.5hp induction motor by using different thickness of rotor lamination steel sheet via FEM

In this paper, the three phase AC induction motor have been thoroughly investigated and analyzed in terms of the induction motor parameter, efficiency and loss segregation. Through out this project, a new rotor which has 0.35mm lamination steel sheet and 10mm rotor bar size is fabricated and compared with the existing rotor which has 0.50mm and 10mm rotor bar size. The comparison is done by software simulation using Motorsolve (IM) Software between existing rotor bar and new rotor bar for the same 0.5HP stator slot design and winding configuration. The Motorsolve (IM) Software is compared in terms of efficiency, power factor and loss fields. Simulation analysis shows that the 0.35mm thicknesses steel sheet has an increment of 1.82% for the efficiency, an increment of 0.03 for the power factor and a decrement of 19.52% lamination eddy current loss as compared to that of 0.50mm steel sheet.

Predicting the localized flux distribution in three phase induction motor between different stator slot size

A three phase induction motor differences of stator slot size is investigated in terms of its localized flux distribution. The search coil induced voltage method is used to analyze the flux distribution in the stator core. For both stator models, the maximum flux density is found near the tooth tip and minimum towards the outer region of the stator core. By saying so, this investigation shows that if there are differences in the stator slot size, the values of flux density differs as well.

Comparison using different thickness of non oriented electrical steel material using FEM software

With market condition today, the economics is such that consumers and engineers are looking for the best fit for the application at the most reasonable cost in purchasing induction motors. This paper compares the performance of torque and rotor loss for two different electrical steel thicknesses (0.35mm & 0.5mm) as designed by FEM Software. Generally, 0.35mm thickness of material can outstand 0.5mm thickness of material in terms of better performance in loss reduction. Simulation analysis shows that the 0.35mm thicknesses steel sheet has a decrement of 18.8% for the rotor loss and an increment of 5.99% efficiency as compared to that of 0.5mm steel sheet.

The impacts of stator materials on induction motor nameplate parameters for high performance

Core materials and magnet wire sizes were analyzed in order to find out the impacts on nameplate for high performance motor. Stack length and back core iron depth of stator geometry design are the parameters involve in these analyses in order to find out the motor model for high performance. The high performance motor is necessary for green energy projects to save electricity and money.
