A random-wound winding for an electrical machine including interconnected wire layers, wherein the interconnected wire layers include randomly wound wires and are configured upon placement in the electrical machine to have substantially the same impedance. Accordingly, the random wound windings can include a first coil having layers of wires randomly wound on the first coil with the layers configured in a first layering order, a second coil having layers of wires randomly wound on the second coil with the layers configured in a second layering order transposed relative to the first layering order, and at least one electrical interconnection configured to serially connect the layers of the first coil to the layers of the second coil such that an average axial position of all interconnected layers is substantially the same. The random wound windings can include a coil having layers of wires randomly wound on the coil with one side of the coil having the layers configured in a first layering order and an opposing side of the coil having the layers configured in a second layering order transposed relative to the first layering order, wherein an average axial position of the layers substantially the same.

A magnet machine includes a magnet rotor. The rotor includes a sleeve and a magnet. The magnet is positioned within the sleeve. A highly electrically conductive, nonmagnetic shield surrounds the magnet. The shield reduces rotor eddy current losses and lowers rotor operating temperature, thereby improving efficiency of the machine.

An electric machine may include a housing having a front end and a back end where the front end is the primary mechanical coupling end. The electric machine may include a stator and a rotor arranged within the housing and a shaft connected to the rotor. The shaft may extend out of the front end of the housing and the shaft may be configured to be rotationally driven by the rotor or to rotationally drive the rotor. The electric machine may also include an electronic controller configured to control operations of the rotor and stator and the electronic controller may be mounted on the front end of the housing.

The present disclosure relates to a system for sourcing and sinking power. The system may have a bi-directional system of electrical components configured for placement in electrical communication with a power source and a load. The bi-directional system may further be configured to source AC and DC power from the power source to the load and sink AC and DC power from the load to the power source. The system may further include a high frequency isolation transformer. In some embodiments, the system may have four input/output channels. The bi-directional system of electrical components may include a line filter configured to reduce harmonic content, a line converter configured for converting between AC power and DC power, a load converter configured for converting between AC power and DC power, and a load filter configured to reduce harmonic content.
