Abstract
An electrical generator for mounting on a railroad car axle end which utilizes the rotation of the axle to generate electricity. The generator includes a housing assembly bolted to the end of a railroad car axle, preferably using the bolt holes that are present on conventional axle ends. The housing includes a tubular rim along which is mounted a plurality of spaced permanent magnets. A stator fastened to a stationary part of the car, typically the outer race of the axle bearing, mounts a plurality of coils in a circular array, closely spaced to the magnets. Electricity is generated whenever the car axle is rotating.
