Xof1 Photo Artifacts 10: NGM Motor
The Xof1 Solar Car has an amazing electric motor. The motor is an axial flux brushless DC motor that can produce 7 hp, yet weighs less then 40 pounds. A typical industrial 5 hp electric motor weighs 200 pounds. In the picture you can see the stamped flat plat copper coils and further inside the iron laminations of the slotted stator. The copper is covered in a varnish insulation which is why everything looks goopy. This motor is made by New Generation Motors and is specifically designed for solar powered cars.

Xof1 Photo Artifacts 9: Electronics compartment test assembly
This is a picture of an early test assembly of the electronics compartment. The big black box is the motor controller. There is also a telemetry radio, the telemetry computer, various patch panels, and a Vicor DC DC converter.
There were probably 100 of these test assemblies. The final system did not include the telemetry computer or radio.
The (scary looking) little brown board in the upper right is a board with calibrated shunts for doing current monitoring.
Observe the tape on the one side of the box. "NO METAL TOOLS....". Dropping a metal tool in this box with the power on would be a very expensive and dangerous light show. When working on an electric vehicle its good practice to completely cover metal tools with fusion tape to ensure they cant short various things.
