In summary, IPMs achieve high levels of integration by incorporating around 30 discrete components in one package. This allows for a simpler layout, reduced BOM cost, and already implemented protection functions. IPMs always come with gate drivers. As motor power increases, IPMs tend to be substituted with PMs. PMs are typically designed to handle higher current/voltage levels. While PMs do not incorporate gate drivers, their topology is not fixed. Finally, ST offers development tools, applications notes, and evaluation software to help engineers get up and running quickly.
