Cluster analysis in multithreaded design of active parts of induction motors

To speed up the process of designing active parts of induction motors, it is proposed to classify the set of basic applications into three basic groups: harmonious, torque, and torque with limited starting current. The significance of particular optimization criteria is determined for each cluster. The universal set of solutions for the subclass of IM are located inside a region delimited by solutions with the greatest significance of basic particular criteria of each of the three groups of applications. Electromagnetic and technological metrics for low-, medium-, and high-capacity induction motors and the most efficient topologies of rotor and stator slots for each of the clusters are proposed. The applicability of copper or iron machines in different areas is discussed. Cluster analysis is noted to be the next step in the transition from automated to almost automatic design of active parts of electric machines.
