| - | There are several ways to classify electrical motors. The most important is dividing them as alternate current (AC) and direct current (DC) motors. In addition there are electrical motors with brushes and brush-less motors, linear motors and rotary motors, nano-motors and large motors and so on. On the other hand, some of the segmentations are provisional. For example, linear motion is achieved usually using rotary electrical motor, which is integrated into unitary body with screw mechanism and treated so as linear actuator. In this chapter, three most common types of electrical motors in robotics are covered: DC motor with permanent magnets, RC servos and stepper-motor. | ||

De plus il existe des moteurs électriques avec balais, des moteurs linéaires et rotatifs, nano-moteurs et moteurs larges et bien d' | ||
