voltage induced on a conductor and on a coil. Introduction to brushless PM motor; sinusoidally excited and square wave

current excited machines; ideal waveforms; driving current needs; torque waveforms. Slot-pole-phase relationships;

induced emf; dependence of induced emf waveform on magnet flux density, conductor distribution and skewing; evaluation

of induced emf waveform for various slot-pole-phase combinations;

Cogging torque; cogging torque waveforms and its source; minimization techniques; skewing effects; effect of cogging

torque reduction techniques on torque ripple; Machine losses; design strategies; demagnetization, efficiency, size and cost

constraints; stator lamination design equivalent circuits and analysis techniques.
