Case Studies: Salient Pole Rotors

NEC has the experience to address the full range of electro-mechanical issues associated with salient pole rotors.
Mounting salient poles to rotor rim.

NEC is experienced with cast and fabricated rotors, including those with segmented rims. NEC has manufactured new field poles for more than a dozen units whose frequency was increased from 25 cycles to 60 cycles, as well as cases where pole laminations were damaged in some way. We have also repaired casting cracks in older rotors and made modifications to rotor rims and pole key assemblies to allow more pole weight and resolve distortion and re-fit issues. Because of the long lead time required to fabricated replacement rotors, our ability to fully rehabilitate almost any component of these rotors can benefit your project budget and schedule.
