Abstract

From the existing literature, the open circuit field due to different magnetisations of the rotor magnets is known. This includes field due to parallel, radial and Halbach magnetisation. This paper presents the generalised analytical model to represent the open circuit fields due to these three magnetisations for a slotless machine. With the armature reaction field, the vector summation of the open circuit field and armature reaction field in the air gap gives the airgap flux density field, which is crucial for evaluating performance parameters and machine behaviour.
