Two different types of semi-analytical models for outer rotor slotless Halbach array PMSMs with teeth for cooling channels are introduced. The first model considers the coils and the teeth for cooling channels as a continuous region while the second model define separate regions for the (virtual) slots and teeth. The accuracy and computational time with respect to a commercial Finite Element Method (FEM) package for the models are compared for static and transient analysis with a 14 pole fractional slot concentrated winding (FSCW) machine.
