Description
Summary:Electromagnetic field analysis based on the analytical solution of Maxwell's equations in two dimensions, is used to predict the torque capability of the reaction sphere; a novel momentum exchange spacecraft attitude control actuator. The performance with three different sphere materials and different supply frequencies is considered together with the sensitivity to changes in the clearance between the sphere and the electromagnetic actuators.
