This paper describes a suspension system in which magnetic actuators are used to simultaneously support and gimbal a flywheel rotor. Through the use of a Large-Angle, Magnetic Suspension (LAMS) system, an array of flyhweels may be used to provide the functions of energy storage and attitude control in a low-earth-orbiting (LEO) satellite. The current state-of-the-art in magnetic suspension technology is examined and candidate LAMS systems are identified. Parametric studies show that, in comparison to suspensions that operate via the attraction of ferromagnetic bodies, a LAMS that employs the Lorentz force is a viable alternative when gimbaling requirements are small (less than 10 deg). When the gimbaling requirement is increased (10-15 deg), a Lorentz-force LAMS shows distinct advantages in terms of reduced mass and power consumption.
