A generator system having an auxiliary forced cooling-oil lubrication system in which a second pump for the fluid is driven in a self sustaining cooling and lubricating cycle, despite the failure of a primary pump action. The second pump can be electrically or mechanically driven to cause a reserve portion of the cooling-oil lubricant to recycle from a secondary reservoir. This secondary reservoir reserves a fluid capacity not circulated by gravity feed in a primary fluid circulating path, which normally returns the fluid to a primary reservoir. A primary pump circulates the fluid through a primary portion of a heat exchanger with an oil-to-fuel heat exchange transfer to sustain the cooling and lubricating functions of the generator system and the failure mode, second pump sustains cooling operations of a permanent magnet generator, despite the failure of a primary pump or loss of fluid circulating in the primary circulation path.

A generator system adaptive, auxiliary forced cooling-oil lubrication system, comprising: a heat exchanger having primary and auxiliary cooling paths; a primary reservoir compartment and a power generation compartment in fluid communication with said primary reservoir compartment, said primary reservoir compartment being adapted for pressurizing cooling-oil through an oil line to said power generation compartment, said cooling-oil lubricant normally being passed through said primary heat exchanger path to dissipate heat; a power generation section of said power generation compartment including composite rotor means with a main rotor section and a permanent magnet section between the ends of a rotor shaft, said rotor shaft being supported by bearings and rotationally coupled to stationary means including a synchronously AC rotating main electric field winding section and a magnet generator winding section for producing main and auxiliary electrical power generation output for said power generation section; first pump means for scavenging the cooling-oil lubricant from said primary reservoir compartment in order to pressurize the cooling-oil lubricant for a forced entry passage to said power generation compartment, with return being to said primary reservoir during normal operational cooling and lubricating of vital rotational and electrical components of said power generation section, when fluid pressure in the forced entry passage is within an established operational range; a residual reservoir section of said power generation compartment in a casing adapted to normally cause a primary recirculated fluid passage of the cooling-oil lubricant from said first pump means, with return to said primary reservoir compartment, and to cause a secondary or auxiliary recirculated fluid passage of a reserve portion of cooling-oil lubricant through an auxiliary fluid passage, upon said first pump recirculation pressure failing to achieve a predetermined level; second pump means adapted for pressurizing the cooling-oil lubricant from an auxiliary exit path from said residual reservoir section for the amount of the reserve quantity of cooling-oil lubricant remaining when the cooling-oil lubricant is no longer being pumped by said first pump means from said primary reservoir compartment; said second pump means being coupled to said composite rotor means of said power generator section when fluid pressure from said first pump means falls below a predetermined minimum pressure in the input passage of said power generation compartment.
