An analytical method is presented for calculation of no-load magnetic field distribution in the slot-less and slotted air gap of a spoke-type permanent magnet (PM) motor. The slot-less air-gap field and the relative air-gap permeance considering the effects of the slots are derived from the conformal transformation. The analytical field solutions are used to predict the cogging torque of an 8-pole,...
The torque constant, together with the back-EMF constant, was originally used in permanent magnet DC commutator motors (PMDC motors) to couple the electric circuit equations with mechanical equations. But it is still an open question whether the concept of the torque constant and the back-EMF constant can be applied to brushless DC (BLDC) motors and permanent magnet (PM) AC machines. This paper presents...
