Magnetic Moment Motor: The Core Power of Leading Precision Guidance Kits
In this article, we focus on the magnetic moment motor within guidance kits, unveiling its mysterious veil and delving into its crucial role in ballistic correction.
The magnetic moment motor is a key component of the projectile guidance kit, with a complex structure and function. Comprised of components such as the airfoil, magnetic cylinder, winding, bearings, and more, its role is not only to provide energy to the system but more importantly to achieve roll attitude control of the airfoil and generate the torque required for trajectory correction.
Its operating principle is exquisite: the magnetic moment motor is integrated with the airfoil design, controlling the magnetic resistance torque by adjusting the current, thereby precisely controlling the roll attitude of the airfoil. In trajectory correction, the deflecting airfoil generates a deflecting torque, decoupling the airfoil from the projectile's roll, while the correcting airfoil generates lateral force and torque, achieving trajectory correction through the magnetic moment motor. This precision control capability enables projectiles to accurately hit their targets.
