A work machine using a direct current power system that isolates reactive loads is described herein. The work machine uses a machine power distribution unit that receives direct current power from two or more battery banks of a power unit, whereby each of the battery banks deliver electrical power on a separate direct current bus. A machine power distribution unit of the work machine receives the electrical power from the battery and is used to isolate the power using bus connectors. One of the battery banks provides power to one direct current bus of the work machine and another battery bank provides power to another direct current bus of the work machine. A reactive load serviced by one of the battery banks is electrically disconnected from another reactive load serviced by the other battery bank.

Systems and methods for operating a divided power distribution system

An end plate for a rotor of a switched reluctance motor is disclosed. The end plate includes an annular body and a plurality of ribs. The annular body has a first axial end, a second axial end, and a thickness. Further, the annular body defines an outer surface and a bore configured to receive a shaft of the rotor. The plurality of ribs extends radially outwardly from the outer surface. The plurality of ribs is adapted to respectively abut with a plurality of poles of the rotor.

End plate for rotors of switched reluctance motors

A multi-stage power module is provided. The multi-stage power module may include at least one heat sink having a first surface, a second surface and an edge, a first set of switches disposed on the first surface of the heat sink, a second set of switches disposed on the second surface of the heat sink, a plurality of capacitors disposed adjacent to the edge of the heat sink, and a bus bar assembly symmetrically coupling the capacitors to each of the first set of switches and the second set of switches.

Low inductance power electronics configuration for electric drive systems

A machine having a series electric drivetrain system includes an engine to provide mechanical energy to an electric generator, the electric generator able to convert the mechanical energy received from the engine into electrical energy, the electric generator including an input shaft extending through the electric generator, a rotor to rotate on the input shaft, and the input shaft is able to rotate an input gear, an idler gear, a pump drive gear, and a rotor gear, a motor to receive the electrical energy and to produce a rotational output, a single speed ratio direct drive to transfer the rotational output of the motor to a torque output to deliver to a drive shaft, and power electronics to control the electrical energy between the electric generator and the motor and to regulate the rotational output of the motor.

Electric drivetrain system and method having a single speed ratio direct drive

A cooling jacket for a battery pack includes a first half and a second half. The first half and the second half are substantially identical and flip-ably connected to each other. A channel is provided in between the first half and the second half. Further, a coolant flows in the channel provided between the first half and the second half.
