Claims

[Scope of utility model registration request]

A satellite despin section that rotates in the opposite direction to the main body of the satellite, a ring-shaped magnet attached to this despin section and magnetized in the direction of the spin axis, and a ring-shaped magnet that is divided into upper and lower sections to sandwich the ring-shaped magnet of this despin section, and that is attached to the spin axis. A spin-stabilized type comprising a ring-shaped magnet magnetized in the direction attached to the satellite body, a motor coil attached to the center of the ring-shaped magnet, and a cylindrical magnet arranged on the circumference of the motor coil. Artificial satellite.
