FAQ - Keppe Motor

1.9. What is the efficiency of a Keppe Motor?

Answer: The typical efficiency of a plain Keppe Motor goes from 50 to 65% in its simplest configuration. Nevertheless, by adding extra coils in strategic points of the stator and using appropriate rotor designs, the Keppe Motor can surpass 90% efficiency.

Household, commercial and exhaust fan prototypes using the Keppe Motor have an average efficiency above 60%, depending on the model. When compared to 20% or less shown by the conventional motors used for the same applications, this difference represents significant economy of energy, worthy of attention of private and governmental entities interested in energy efficiency.
