ABSTRACT:
The present invention relates to a generator system connected to an external A.C. power source for supplying electrical A.C. power to a load for prolonged periods when the external electrical A.C. power source fails. The system comprises a main A.C. generator unit capable of generating an A.C. potential at a selected frequency and voltage for the load, and an auxiliary A.C. generator is connected to the main generator for generating A.C. at a high frequency. This high frequency A.C. is conveyed to a relatively small high speed motor and flywheel unit in a sealed chamber, which unit at full speed can store large amounts of rotational kinetic energy. The high speed motor has a stator armature with a power winding and an excitation coil, and a cooperating rotor of soft magnetic material having a cylindrical surface with a layer of magnetizable permanent magnet material thereon. When energized with the high frequency A.C., the power winding causes the rotor to rotate as a hysteresis motor. When the external electrical A.C. power source fails, the excitation coil is energized with high frequency A.C. to magnetize the layer of permanent magnet material into a pattern of north and south magnetic poles which will enable the rotational kinetic energy of the rotor and flywheel to generate high frequency A.C. of constant frequency in the power winding which is supplied to the auxiliary generator to cause it to function as a synchronous motor to drive the main A.C. generator so that it will keep on producing the A.C. potential to the load.
