What is a Micro DC Motor

Micro DC motor refers to a rotating motor whose output or input is DC power, and an electromagnetic device that converts or transmits power according to the law of electromagnetic induction. It is represented by the letter "M" in the circuit. The micro DC motor has two pins, which can be rotated by connecting the positive and negative poles, and reversed when the positive and negative poles are reversed. The DC motor rotates very fast, but the torque is small. Suitable for all kinds of products that require high speed, such as four-wheel drive.

Micro DC motors have 3 different excitation modes: permanent magnet, separate excitation and self-excitation (shunt excitation, series excitation, compound excitation)
