Electric winding impregnation optimizes the product overall performance, increases the coil insulation, the resistance to stress and temperature generated during normal operation. It also minimizes the risk of short circuits in the windings and increases heat exchange, extending motor working life.

Tecnofirma takes care of your products by studying and applying the best impregnation process for each customer. An incorrect method or insufficient impregnation can considerably shorten the working life of your electric motor.

Impregnation Methods / Technologies for Hairpin stators and stators / rotors with traditional winding

Tecnofirma offers a wide range of solutions for the insulation of traditional and new-generation windings. We develop in our lab the best impregnation technology/method, based on the foreseen application type.

Thermal processes

Over the years, Tecnofirma has developed alternative thermal processes used today in various plants as a replacement or in combination with traditional convection ovens according to production needs. In particular, combining multiple methods where are high cadences is necessary.

  • Induction heating: process used for medium and large stators in high production rate plants.
  • Infrared technology: IR lamps installed inside traditional ovens to speed up the entire process or to restore the stator temperature in some process phases.
  • Joule Effect Technology: process used for rotors and stators through the supply of current in some phases or during the whole process.
