DC motors are relatively easy to control, both direction and speed. Motor rotation direction is determined by power supply polarity and H-bridge driver is often used when DC motor is controlled by microcontroller. text/html 2020-07-20T12:00:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.robolabor.ee/homelab/en/examples/motor/dc?rev=1595235600&do=diff DC motor Necessary knowledge: [HW] User Interface Module, [HW] Combo module, [AVR] Counters/Timers, [AVR] Analog-to-digital Converter, [LIB] Motors, [LIB] Analog to Digital Converter Theory Permanent magnet DC motors are very common in different applications, where small dimensions, high power and low price are essential. Due to their fairly high speed, they are used together with transmission (to output lower speed and higher torque). text/html 2020-07-20T12:00:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.robolabor.ee/homelab/en/examples/motor/servo?rev=1595235600&do=diff Servomotor Necessary knowledge: [HW] User Interface Module, [HW] Combo module, [AVR] Counters/Timers, [AVR] Analog-to-digital Converter, [LIB] Motors, [LIB] Analog to Digital Converter Theory RC (radio-controlled) servo-motors are very common actuator devices in robotics and model building. RC servo motors are consisting of small DC motor, reduction gear and control logic device. Usually the rotor of the servo motor moves to a certain position and tries to maintain that position.

Unlike DC motors, stepper motors do not have brushes nor commutator – they have several independent coils, which are commutated with exterior electronics (drivers). Rotating the rotor is done by commutating coils step by step, without feedback. This is one of the faults in stepper motors – in case of mec…
