ROTORS & STATORS FOR ELECTRIC MOTORS AND GENERATORS

Materials used in Rotors and Stators range from Silicon to Cobalt Iron, and in varying thicknesses from 0.5mm to 0.1mm in order to support demanding increase of efficiency for Aerospace applications.

The size range for Stacks is from 250mm diameter and 20Kg down to 10mm and 25g.

Typically we take care of the full supply chain starting from raw materials and delivering finished products. If needed we can use customer's pre issued laminations.

Typical manufacturing methods are:
Bonding
– using an applied thermosetting adhesive to bond each lamination to the next.
Welding – TIG weld to join each lamination together.
Impregnation – where adhesive resin is drawn into the stack under vacuum.
Mechanical – using tie-rods or similar for mechanical retention of laminations.

Completed Stacks can be assembled onto Armature Shafts with Commutators, or fitted with End Plates or Coil Supports. Copper Damper Bars can also be installed.

The bores and diameters of Rotors and Stators can be finished machined to Customer drawings and supplied direct for winding.

We can advise on suitable production methods for various project volumes, and can supply the initial prototypes as wire cut stacks from raw block material. Then progress with short life stamping tools before final  production tooling is required.

Our manufacturing engineers can support you in identifying tolerances and geometries for cost effective manufacture.
