EC Technology
Advantages of EC Technology
Made in Germany
Our energy-saving EC motors are developed and manufactured entirely on our modern production line at our Kü nzelsau headquarters. Through the combination of know-how and innovative manufacturing techniques, we achieve quality that meets high standards.
Functional Principle
The motor position depends on the voltage supplied by the frequency converter module (similar to the principle of the frequency converter). EC commutation electronics differ from frequency converters in that they decide how to supply current (commutation) to the motor phases in the stator depending on the position, direction of rotation and default values. The permanent magnets in the rotor will generate the magnetic field required for full load production. This allows for low noise and continuous motor speed control.
Fan with EC-Drives
Rosenberg offers a large number of energy efficient fans with EC drives in the fields of standard fans, OEM application fans and ventilation fans. EC-fans are used wherever economical energy use and simple control according to actual ventilation needs are required. The integrated electronics enable the EC fan to perform well every time. All that is needed is a control signal.
Calculation Examples
Rosenberg EC fans have a high energy saving potential at full load, especially at part load. Under the same airflow, the efficiency loss is significantly lower than that of traditional AC motors. The improvement in energy efficiency has led to a 2-year reduction in carbon monoxide emissions. In addition, the investment cost of fan speed control is low. No control transformers, frequency converters or phase angle controllers are required. All necessary components are included in the EC motor electronics. Rosenberg modern EC technology is not only wallet-friendly, but also very friendly to the environment.
