The design of any electrical machine is highly interdisciplinary. As highlighted in the foundational chapters of the text, a successful design must simultaneously balance four interconnected subsystems:

The heart of any electrical machine is its magnetic circuit. Designers must calculate the flux density in the core, teeth, and air gap. Selecting the right magnetic materials (such as silicon steel laminations) is critical to minimizing core losses (hysteresis and eddy current losses) while ensuring the machine does not saturate under operating conditions. 2.

Balancing the ratio of length to pole pitch to optimize commutation and minimize cost.

This involves the calculation of windings, slot dimensions, and insulation systems. Designers must determine the correct conductor size to handle the rated current without overheating, while optimizing the slot fill factor to maximize power density. 3.
