Tooth arc 32 ° (mech) Stator axial 200 mm length (2×100) Airgap 1 mm length Magnet 2 mm thickness Stator 136 mm outer diameter Stator 64 mm inner diameter Motor Rotor outer 62 mm dimensions diameter core 10 mm thickness body 12 mm width Stator core 12 mm thickness Rotor core 10 mm thickness Tooth tip 1.0 mm edge thickness Slot 20.5 mm The predicted variation in the open-circuit flux density along a path at the mean radius of the airgap is shown in Figure 328, for the particular case of a rotor angular displacement of 0º. The mean value of the flux density under the tooth of phase 1 is 0.69T, a value which in reasonable agreement with the 0.65T predicted by equation (3) which forms the basis of the analytical force constant calculations.
