  • Abstract
    This paper presents an analytic based eddy current torque analysis procedure. The equations are derived using the second-order vector potential and the magnetic rotor is modeled using the magnetic charge sheet concept. The formulation enables the damping and stiffness equations to be derived. The equations are numerically computed and the accuracy is compared against experimental torque and power measurements.
