Abstract:
The results of experimental and analytical studies of the wind energy system with permanent magnet eddy current heater are presented. Power generated in the ferromagnetic solid steel by eddy currents is proportional to the square root of the rotation speed of the wind turbine to the third power. Heater efficiency exceeds 90%. In the 3…50 kW power range, i.e. wind turbine rotation speed 400…100 rpm, is appropriate to use the eddy current heater. For power less than 3 kW Joule machine has advantages.
