Claim 11:
12. The downhole electric generator of claim 10, further comprising the second alternator assembly coupled to the first alternator assembly, the second alternator assembly including:
a second casing;
a second rotor disposed within the second casing, the second rotor including,
a second cylindrical rotor core;
a second plurality of permanent magnets disposed within or on the second cylindrical rotor core; and
a second drilling fluid channel extending axially through the center of the second cylindrical rotor core; and

a second stator disposed within the second casing, the second stator including,
a second cylindrical stator core concentrically disposed between the second rotor and the second casing;
second conductor windings within the second cylindrical stator core; and
a second plurality of radially distributed fluid channels extending axially within the second cylindrical stator core between the front end of the second cylindrical stator core and the back end of the second cylindrical stator core;

a second coupling joint member coupled with a first coupling joint member of the first alternator assembly; and
a second electrical interface configured to electrically couple the second alternator assembly to the first electrical interface of the first alternator assembly, wherein the second alternator assembly receives the electrical power generated by the first alternator assembly.
