AC motors for high-performance drives: a design-based comparison

Three AC motors are compared for application in high-performance controlled drives: induction, brushless, and synchronous reluctance motors. Their design is optimized under common design assumptions, Then, the given stall-torques are compared to each other. In addition, the quadrature reactances are compared, as affecting overload and flux-weakening performances. Finally, applicative considerations are given, thus defining the most suitable solution for each field.
