The KOSTAL INVEOR variable frequency drives control process

Our motor-mounted variable frequency drives of the INVEOR series use the pulse injection process that we developed and patented in-house. This enables a drive controller design without encoder sensors, allowing you to benefit from numerous advantages:

  • Fewer failures since delicate encoder sensors are not needed
  • Due to the elimination of sensors, reduced bills too
  • More application options in harsh environments, since the most sensitive component is eliminated with the encoder
  • Longer product life due to reduced components and cable connections

Yet you do not have to compromise on performance in any way. This is because the pulse injection process offers outstanding performance parameters, including the elimination of the overload limit.

Learn more about this smart process of sensorless control technology today.
