Design and Performance of a Converter Optimized AC Machine

Abstract
The design and performance of a unique concentrated winding machine specifically designed for operation with a static power converter is described. When operating in tonjunction with a converter supply, the machine is theoretically capable of 15 percent more power output for the same active copper and iron than a conventionally designed synchronous machine of the same rating. The performance of the machine operating as a generator feeding a rectifier load is described, the theoretical predictions are compared with test. The potential of such a machine operating as a motor is also described.
