FAQ - Keppe Motor

1.3. How does a Keppe Motor work?

Answer: Electric motors transform electric energy into mechanical energy, and electric generators do the opposite, i.e., transform mechanical energy into electric energy.
The Keppe Motor comprises a motor feature (electricity being transformed into mechanical energy) and a generator feature (mechanical energy being transformed into electricity) in balance at the point of resonance of the system.

System’s highest efficiency is reached when the resonance between the two components of action (motor feature) and complementation (generator feature) takes place. The resonant point of this system includes the electric power supply (domestic grid or battery) and the load on the shaft.

The Keppe Motor contains a magnetic rotor with permanent magnets which rotates inside the stator coils. When the magnet is set in motion by the supply voltage applied to the coil (motor feature), it creates additional voltage in the coil terminals (generator feature), increasing the magnetic energy stored in it. This energy enters in resonance with the power grid’s energy through pulses of varying intervals determined by the Keppe Motor itself and this is the nature of its high efficiency. As consequence, one of the best advantages of the Keppe Motor is that it runs cold, which is an indication of its high efficiency and guarantee of durability.

Nevertheless, for all this to occur, it is not enough to make a motor with a different design – you must also change the power supply, otherwise, resonance cannot be achieved.

The best way to reach resonance is to let the motor interrupt its own power supply according to its own structure, without interfering with its operation. Because of that, the typical and necessary power supply of the Keppe Motor is PDC (Pulsed Direct Current), the only supply that allows the system to reach resonance. Depending on the motor design and parameters, such as wire gauge, presence or absence of an iron core, type of magnet, coil inductance, etc., the entire system will automatically search for its point of resonance for the load and voltage specified. At this point the electrical current decreases to the minimum necessary to perform the desired work. This minimum is always lower than that required by conventional direct or alternating current to perform the same task.
