What does the paper present?
Many applications in the field of microcontrollers have the task of driving some motors.
For example, the applications of car - motors from electric windows, dashboard motors, etc. or applications in the field of peripheral equipment - printer, hard disk, etc. Or industrial applications - valve actuators, valves, etc.
The engines can be:
- direct current with or without brushes;
- stepper motors;
- of alternating current with induction;
- motors with switched reluctance.
The first two categories of engines are used more often in microcontroller applications therefore will be addressed in this chapter.
An engine can be controlled by a microcontroller both directly and through specialized, programmable interfaces.
