The working principles and characteristics of the following electric motors

4 important questions on The working principles and characteristics of the following electric motors

At what other motortype is the BLDC motor often compared? And why?

A stepper motor. Because we can make a rotation step by step and there is no magnetic fields that fits in between the two steps

What happens when adding a ferromagnetic core?

The amount of field lines (or magnetic flux) increase

Why do a-synchronous motors need an inverter?

Synchronous motors need an inverter in order to make them start from 0 rpm
