چکیده

Recently, the industry is more and more interested in fractional slot concentrated windings (FSCW), because of many advantages such as high power density and low manufacturing costs. Novel FSCWs often consist of several winding systems. This structure allows the creation of good MMF distributions with low space harmonic contents and reduces undesirable side effects, such as localized core saturation, eddy current loss in the magnets, noise and vibration. Good examples for this are 18teeth/10-poles and 30-teeth/14-poles combined wye-delta windings. In this paper, a new three phase single tooth concentrated winding with a simple wye connection for induction machines is presented. The combination of this winding with a squirrel-cage rotor is especially suitable for low cost applications.

General Closed-form Analytical Expressions of Air-gap Inductances for Surface- mounted Permanent Magnet and Induction Machines

General closed-form analytical expressions for airgap inductance of surface-mounted PM and induction machines are derived without the assumption of sinusoidally wound windings. The expressions are suitable for all singleor doublelayer, concentrated or distributed windings, and demonstrated to be identical with the winding function approach and share the same advantage that all the harmonics are...

Improvement of Electromagnetic Forces in a Single-Phase Induction Motor by Providing a New Winding Distribution

Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
