About AC, DC & Servo Motors
Pololu AC, DC & Servo Motors
AC, DC, and Servo motors are all types of motors commonly used in electronic circuits. AC (alternating current) motors are driven by an alternating power source, typically from a wall outlet. They have a simple design and are commonly used in home appliances such as fans and refrigerators.DC (direct current) motors, on the other hand, are driven by a direct power source, such as a battery, and are commonly used in electronics such as robots and drones. They have a more complex design with brushes and commutators.Servo motors are specialized motors that use feedback control to precisely control the position, speed, and direction of the motor shaft. They are commonly used in robotics and automation, as they offer high precision and accuracy.In terms of electronic components, AC and DC motors require a power source and a controller such as a motor driver to function. Servo motors, in addition to these components, also require a feedback sensor, such as a potentiometer, to accurately control the motor's position. All three types of motors play essential roles in electronic devices and are chosen based on the specific requirements of the application.
