Compared to a poor analog solution, an MCU-based drive shows many
advantages. Some of them are:
Universal motors are still used where brushes are accepted, and
universal motors driven by power switches are used where a low price
is required. This section contains information and descriptions about all
features of a suitable MCU, IGBT, and diode.
