Mmf waveform generated by a single/three phase winding with a sinusoidal current supply:

• slider "" enables to switch from single-phase to three-phase winding
• slider "" enable to select from 1 to 4 slots per pole per phase
• move slider "" to see how the waveforms change as functions of time
• check boxes "single coil mmf", "stepwise waveform" and "fundamental harmonics" enable to show the corresponding components

N.B.: with the single-phase winding is assumed to span over (2/3 of the pole pitch)
