Abstract
The present invention provides a single piece machined rotor comprising a shell having an upper lip and a lower lip, with a pocket formed between the upper lip and the lower lip for mounting magnets therein. The magnets are fixed in place within the inner sidewall of the rotor with an adhesive and spacers. The spacers are positioned between the magnets and are held in place on the shell of the rotor by fasteners. The spacers may be of any type of non-magnetic material that can absorb the heat of the engine. The rotor also preferably includes triggering protrusions and balancing cutouts machined into the shell of the rotor. The cutouts or grooves may be machined into the inner sidewall or the outer sidewall of the rotor. A plurality of timing teeth used for engine speed sensing maybe machined into the single piece rotor assembly. The present invention also contemplates a method of machining the entire rotor out of a single piece of material.
