Feature 









Structure diagram



Coreless DC motors differ from traditional DC motors in significant ways. The most obvious and important difference is the rotor winding. Instead of coils wound around a stack of iron laminations, the coil is formed as a thin hollow cylinder . The stator with its permanent magnets  supplies the magnetic field flux and fits in the hollow center of the winding. It's rigidly affixed to the outside motor housing, which completes the magnetic circuit. The rotor is supported by bearings and rotates around the magnetic core.
