The Steinmetz’s parameters are essential for calculation of the losses in soft magnetic materials. However, due to the non-uniform flux density distribution in the soft magnetic material cores, the fitting error of the original Steinmetz equation (

This paper proposes a method to measure the proximity losses of the Litz wire. A test bench is built to produce uniform alternating magnetic field in two air gaps. When the Litz wire are put into the air gaps, the proximity losses of the Litz wire ar

This paper presents feasible slot/pole number combinations of machines with two slot-pitches. They are becoming popular since they not only exhibit the low torque ripple but also the low harmonic content of the magnetomotive force. Some examples of s
