An  Innovated, Patented Technology

Conventional generators can be described as having a fixed quantity and location of magnetic pole sets. These pole sets then interact with copper windings in order to generate electricity at a certain frequency for a given rotor speed. Slowing the rotor speed would then decrease the output frequency. The patented Written-Pole® Technology allows the magnetic pole pattern on the magnet layer to be changed to a desired pattern while the machine is rotating and therefore breaks the relationship between rotor speed and output frequency.

This same technology is used in the motor. Re-magnetizing or rewriting the poles on the magnet layer in the motor enables an optimum torque and high horsepower to be achieved. Additional advantages include low per unit starting current to horsepower ratio, (typically less than 3 times full load current) which greatly reduces voltage sags on the line.
