Abstract:

This paper reports on the study of winding asymmetries in small synchronous generators. These types of generator are commonly used in diesel generator or back-up systems and are usually no more than a few or few tens of kilowatts with two, four, or six salient poles. The three-phase winding is 120 deg pitched, but often, lap windings are not used, rather, a hybrid of concentric winding and double layering is utilized. There are sound manufacturing reasons for this, and these are explained. This leads to small asymmetries in the phase-belt inductances and field-induced voltages. This is examined and validated experimentally. This paper discusses the techniques that are used to analyze the machine. These are analytical methods. The methods address the correct positional coil groupings in the slots to obtain back electromotive forces, mutual and self-inductances, and line currents. These are obtained over a varying load range. © 2006 IEEE.
