- Abstract
- This paper presents the design of an Interior
permanent magnet (IPM) synchronous machine to improve
machine performance by increasing saliency ratio and
minimizing the leakage flux through the ribs and air
barriers of an IPM machine. A bar-type IPM basic model is
taken and two variables, variable 1 as factor-A and variable
2 as factor-B are analyzed. Factor-A is the radial distance of
the rotor air barrier and factor-B is the rotor tangential rib
angular distance in degrees. The two variables greatly affect
the targets of the designed IPM i.e. saliency ratio and
leakage flux. A 3-step design process is followed to achieve
the desired targets. In step-1, the design variables, factor-A
and B, are evaluated and the effect of each variable is
examined on machine performance individually. In step-2,
the best combinations of design variables are taken and an
iterative optimization is performed for checking the
combined effect of both variables on output torque and
power factor. In step-3, the model is optimized using the
Kriging method and Genetic algorithm (GA) for improved
torque characteristics compared to the basic IPM model. All
models are analyzed with the same machine size, operating
conditions, and magnet volume using 2-D finite element
method (FEM).
