title = "A General Airgap Permeance Model Applicable to Integer and Fractional Slot Permanent Magnet AC Machines",
abstract = "The airgap permeance function plays an important role in rotating electrical machines, and permanent magnet AC machines in particular. It allows the prediction of the spatial airgap flux density distribution, which in return enables calculation of important performance metrics such as torque, phase voltages and core loss. This work studies and compares different analytical airgap permeance functions and then proposes a modified permeance function which is shown to be more general and applicable to machines with both integer and fractional slot/pole combination. The analytical results are benchmarked against Finite Element Analysis models to check for their accuracy, with good matching results reported using the proposed model for three different permanent magnet AC machines configurations.",
