Electric Powertrain System Having Bidirectional DC Generator
First Claim
1. ) An electrical powertrain for use with an engine and a traction device, comprising;
- a DC motor/generator operable to;
receive at least a portion of a first mechanical output from the engine and produce a DC power output for the traction device; and
receive DC power and produce a second mechanical output to drive the engine; and
a drivetrain operable to;
receive the DC power output from the DC motor/generator and use the DC power output to drive the traction device; and
generate DC power directed to the DC motor/generator to drive the enginewhen the traction device is operated in a dynamic braking mode.

Abstract
An electric powertrain for use with an engine and a traction device is disclosed. The electric powertrain has a DC motor/generator operable to receive at least a portion of a first mechanical output from the engine and produce a DC power output. The DC motor/generator is also operable to receive DC power and produce a second mechanical output. The electric powertrain further has a drivetrain operable to receive the DC power output and use the DC power output to drive the traction device. The drivetrain is also operable to generate DC power when the traction device is operated in a dynamic braking mode.
