CAPITAL SPARES FOR MOTORS AND GENERATORS

Through its reverse engineering capabilities, Nidec Industrial Solutions can manufacture capital spare parts (Rotor Poles, Stator Windings and Brushless Excitation systems) for any kind of electrical machine.
We cover a wide range of powers on both synchronous and asynchronous machines (installed references on generators for rotor coils up to 300MVA and stator bars up to 180MVA).

ROTOR POLES

  • Complete Finite Element Method (FEM) calculation for rotor poles to ensure component performance and reliability
  • Supply of poles and rotor coils of different sizes and fixing method including dovetails, hammerheads and bolts
  • For older generators we can supply round head coils; replacing only the copper part of each pole

STATOR COILS

  • Vacuum Pressure Impregnation (VPI) of windings
  • Diamond coils and Roebel bars for windings developed in Resin Rich Technology including both design and manufacture

BRUSHLESS EXCITERS

  • Brushless exciters for any kind of generator including design & manufacture
  • Upgrade old static and dynamo generator exciting systems to brushless exciters without impact on other components
