    The steady-state theory of eddy-current couplings with homogeneous ferromagnetic drums is derived and shown to be valid by tests on an experimental coupling. The effect of machine parameters on peak-torque conditions and a normalized torque-speed relation are given. The flux-density distribution across the pole face under load was measured and correlated with measured torque and speed. Measurement... View full abstract»

    Basic expressions are derived for the relationships between excitation current, speed, and torque of an eddy-current coupling with a solid iron eddy-current member. This paper is concerned only with eddy-current couplings of the inductor or unidirectional flux type; however, the method has been applied also to other types of eddy-current machinery. Necessary approximations are made for the theoret... View full abstract»

    The equivalent circuits applicable to many power system switching conditions can frequently be reduced to one or more series or parallel RLC (resistance-inductance-capacitance) circuits. It is shown that the responses of these circuits to a variety of stimuli can be expressed on a per-unit basis, as families of dimensionless curves involving one parameter. Such curves are presented and are then us... View full abstract»

    Power transmission load flow studies are generally based on the assignment for each bus of either voltage or reactive volt-amperes. Reduced system loss may be obtained by more critical voltage adjustment. For each variable voltage bus an optimum voltage is found which gives minimum loss in the neighborhood of the bus. An iterative procedure with a damping factor appropriate to the system is used i... View full abstract»

    The components of the magnetic vector potential are determined for current elements in radial, peripheral, and axial directions existing between two parallel planes of infinite permeability and resistivity. The total potential due to a closed distribution of currents can be found by integrating the elementary contributions. Flux density is given by the curl of the magnetic vector potential.
