IMPREGNATION MACHINES
FOR ELECTRIC MOTORS

Impregnation machines for electric motors

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.

Potting and Dispensing: Methods, Machines and Applications

Dispensing, in industry and production contexts, represents an impregnation and encapsulation process with the aim of applying resins in the windings of electrical and electronic components. This technology is used in a vast range of sectors, but it is in the automotive industry where Tecnofirma has invested, and continues to invest, in research and development of specific solutions designed to give the treated piece extremely high-quality standards.

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.
