• AC Motor

    Basic AC Motor Operation. An AC motor has two basic electrical parts: a stator and a rotor as shown in Figure 8. The stator is in the stationary electrical component. It consists of a group of individual electromagnets arranged in such a way that they form a hollow cylinder, with one pole of each magnet facing toward the center of the group.

  • How Servo Motors Work

    The guts of a servo motor (L) and an assembled servo (R) Servos are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire. There is a minimum pulse, a maximum pulse, and a repetition rate. A servo motor can usually only turn 90 in either direction for a total of 180 movement.
