Abstract
This article analyzes the magnetomotive forces (MFFs) created by fractional coil windings with number of coils per pole and phase q < 1 in slotless synchronous electric machines with permanent magnets. The harmonic composition of the MMF created by these windings is given. The influence of the coil width on the amplitude of the operating harmonics of the MMF is shown.
