    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for performing electrical machine electromagnetic analysis in the frequency domain. SOLUTION: The method and apparatus are applicable to both poly phase and single phase electrical machines whether balanced or unbalanced (source, windings, magnetics, harmonies). In an exemplary embodiment of the method, magnetic analysis includes selecting and loading (104) electrical machine manufacturing data, such as a stator and rotor geometry and winding design, for example. If the power supply is a voltage source, stator currents are estimated (108). If the power supply is a current source, stator currents are computed. Using the stator current, estimated or computed, a magnetomotive force spectrum is computed (110). From the spectrum, a permeability distribution is computed and tested for magnetic convergence. When there is both magnetic and voltage convergence, the analysis is complete, otherwise the process is repeated.

    Abstract: A wind turbine generator includes a stator having a core and a plurality of stator windings circumferentially spaced about a generator longitudinal axis. A rotor is rotatable about the generator longitudinal axis, and the rotor includes a plurality of magnetic elements coupled to the rotor and cooperating with the stator windings. The magnetic elements are configured to generate a magnetic field and the stator windings are configured to interact with the magnetic field to generate a voltage in the stator windings. A heat pipe assembly thermally engaging one of the stator and the rotor to dissipate heat generated in the stator or rotor.

    Abstract: A system for speed-sensorless control of an induction machine includes a flux regulator and torque current calculator for operating the machine in a heavily saturated state to produce a saturation induced saliency; a saliency tracker for tracking an angle of the saturation-induced saliency; a signal injector for injecting an AC signal aligned with a saliency axis; voltage and current determiners for determining stator voltages and currents; and a rotor flux calculator for using the saturation-induced saliency angle, the determined stator voltages, and the determined stator currents to determine a magnitude and a location of a rotor flux vector. The flux regulator and torque current calculator is adapted to use the rotor flux vector to control the induction machine.
