MANUFACTURE OF COMPONENTS FOR GENERATORS AND ELECTRIC MOTORS: STATOR, ROTOR AND POLE PACKED CORES

Donako manufactures stator, rotor and pole core packed cores for winding-ready electric generators in the hydro, wind and nuclear power sectors, as well as electric motors of the following types:

Housed stator pack:

• split and unsplit,
• with welded and screwed lugs,
• with straight and angled core grooves,
• with walls or pressure segments,
• pack housed via baking.

Slip-on type stator pack with transversed outer diameters of intermediate and lock rings for subsequent insertion into the frame housing.

Rotor pack

• with pressure rings or segments,
• with or without hub and hub for shaft,
• hub assembly in baked pack,
• shaft mounting in rotor pack without hub.

Dimensions and tonnage of electrical machinery components:

• Inner diameter of stator cores approx. (0.7 – 4 m),
• Outer diameter of rotors approx. (0.5 – 3m),
• Due to crane lifting capacity including machine rotation up to 50 tonnes.
