Digital prototyping – digital rewind

Digital prototype is an easy way to check the coil fit in the armature before the first conductor is cut. Digital rewind of armature allows to check the spaces between coils. Appropriate space required for easy coil insertion to armature comes from experience with more than 30 different coil products we designed using 3D modeling software. The final 3D coil model after corrections is used for design of tooling we need for production. Manufacturing data comes from native 3D model.

Prototype manufacturing, check and testing

During prototype manufacturing, all the tooling is production tested to produce excellent bending and shaping of the conductors without damaging the insulation. Corrections are made on tooling to get excellent coil shape, continuous evolvents. Coils are checked in armature model. Spaces between coils are compared to CAD model of the winding. Coil behavior during inserting in armature model shows the next steps in final coil tuning. The whole project is evaluated and Know-How is increased.

Value added coils

We supply Traction motor coils with excellent properties and geometry for faster and easyer rewind of traction motor armatures. The Use of our coils brings reduced rewind time, increases quality of repair work.
