We have developed and tested a new shape of permanent magnet synchronous generator (PMG) rotor for a large scale wind turbine generator system. The new rotor structure has ventilation flues between poles that provide two advantages: (1) effective cooling of the permanent magnets, and (2) reduced eddy current loss.
A fast calculation method for parametric survey is needed when designing motors. We propose a new method for analyzing the harmonic components of air-gap flux density distribution in three-phase wound rotor induction motors. The proposed method is based on analytical equations for permeance and magnetomotive force distribution, considering the influence of the circumference slot arrangement and winding...
This paper describes a method to analyze harmonic components of the air-gap flux density distribution and the torque of 3-phase cage induction motors, considering the influence of circumferential slot arrangement, stator winding pattern, and distribution of air-gap permeance due to leakage flux. The proposed method is based on an analytical model of the permeance and magnetomotive force distributions...
Accurate determination of field currents and reactances is important for design of doubly fed induction generators for wind turbines. An analysis method using finite elements for the saturated reactances and field currents at any balanced steady-state conditions of the generators has been developed, dq-axis equations with cross magnetization are shown and all the reactances in them are calculated...
