Rotor support method for generator of hybrid application

A drivetrain for an electric or hybrid vehicle comprising:

• an engine including a crankshaft;
• and
• a generator driven by the crankshaft of the engine;
• wherein the generator includes:
• a housing including an end cover having an axially extending center support;
• a stator supported in the housing;
• a rotor assembly supported for rotation in the housing relative to the stator;
• and
• a center shaft coaxial with the rotor assembly;
• wherein the center shaft is supported for rotation at a first axial position by the center support of the end cover;
• wherein the center shaft extends axially from the center support and supports the rotor assembly at a second axial position;
• and
• wherein the rotor assembly is supported at the first axial side of the generator by a support plate extending radially between a carrier of the rotor assembly and the center support of the housing.
