EXCITER HAVING THERMALLY ISOLATED DIODE WHEEL AND METHOD OF REMOVING DIODE WHEEL

摘要

The exciter includes an exciter rotor shaft (30), a thermal insulation layer (40) mounted to the exciter shaft (30), and a diode wheel (25) having a wheel hub (26). The wheel hub (26) of the diode wheel (25) is mounted by an interference fit to overlie and abuttingly contact the thermal insulation layer (40) positioned on the exciter rotor shaft (30). The thermal insulation layer (40) is positioned on the exciter rotor shaft (30) and between the shaft (30) and the diode wheel (25) in a location where electrical insulation is not necessary.
