Coreless Motor

記事 Coreless Motorのアイキャッチ画像

A cylindrical permanent magnet is used inside, the outside rotor has no core, and the coil is integrally formed.

Run the current through the coil and rotate the rotor.


① Quick responses are possible because the rotor is light and the moment of inertia is small.

② Since there is no core in the rotor and it is not affected by the permanent magnet, there is little cogging,Rotation is smooth, vibration and noise are small.

③ Since a compact rare-earth magnet with high magnetic properties is used and the rotor is formed of a coil,It is possible to reduce the size and weight of the motor.
