DC Electric Motor
This motor is with much stronger vibration force than other brushed pancake motors. Compare to other typs, coin motor is cheaper. FPC connection is more expensive than wire, however, FPC is better for saving space and more durable than wire.
Electric DC Motor
In an electric motor the moving part is the rotor which turns the shaft to deliver the mechanical power. The rotor usually has conductors laid into it which carry currents that interact with the magnetic field of the stator to generate the forces that turn the shaft
