Abstract

The paper deals with the analysis of a new type of single phase claw pole permanent motor with single side axial flux configuration. The compact structure and the adoption of advanced materials are favorable for the use in high speed ventilation and pumping systems, where efficiency represents a key issue. A preliminary analysis is carried out by means of 3D FE magnetostatic simulations to check the main electromagnetic performances at a predefined steady state operation. As a result, a skewed configuration is defined, yielding an appreciable improvement with respect to the initial one. Then a mathematical model is developed to simulate the actual dynamic operation, taking into account the nonlinearity of the electromagnetic parameters. The results obtained confirm the motor suitability to drive low rated loads with high efficiency and constant power operation in a wide speed range.
