HYBRID ELECTRIC POWER SYSTEM WITH DISTRIBUTED SEGMENTED GENERATOR/MOTOR
First Claim
1. A hybrid electric power system for powering a multi-wheeled hybrid electric vehicle comprising:
- a thermodynamic engine powered by a fuel, said engine mechanically connected to drive a first electrical machine;
a second electrical machine adapted to drive at least one driven wheel of said vehicle; and
at least one electrical energy storage system operable to store electrical energy generated by at least one of said first or second electrical machines;
wherein at least one of said first and second electrical machines is a segmented electrical machine comprising;
(a) a plurality of pairs of stator segments, each said pair comprising first and second stator segments, each first and second stator segment of each said pair comprising at least one stator winding; and
(b) a rotor segment comprising at least one magnet;
wherein each of said pairs of stator segments are physically separate from and substantially magnetically decoupled from each other said pair of stator segments.

Abstract
An apparatus is disclosed for a hybrid electric power system for use in a multi-wheeled hybrid electric vehicle, and particularly for use in hybrid electric vehicles designed for operation in hostile environments where reliability and survivability of the propulsion system of the vehicle are important. The hybrid electric power system advantageously comprises at least one segmented electrical machine having multiple pairs of parallel stator segments with a magnetic rotor segment between each pair, for generating power from a thermodynamic engine, or for providing power to a driven wheel of the hybrid electric vehicle. A hybrid electric power system is also provided which comprises at least one distributed segmented electrical machine which comprises a distributed electrical energy storage system.
