Coreless motors are a type of DC motor that carries its advantages in its ability to operate in fast and dynamic movements thanks to its hollow rotor. This design removes inner laminations and an iron core which in turn eliminates iron losses, reduces mass and increases speed and efficiencies. Because of this, these ERM motors are often found in applications that require the fast movements and high efficiency output.
